Ultrasound distance alarm

Materials for this activity: 

Ultrasound Sensor
Jumper Wires
Arduino and USB Connector

These are for part 2

LEDs 
Buzzer
Breadboard

What is Ultrasound?

Several animals send out high-frequency sound that reflects off of other objects. A sound that is a higher pitch than humans can hear is called ultrasound. They then sense their own reflected sound when it comes back. The loudness and time it takes to come back depends on the distance to the object. 

Ultrasound sensor wiring and coding basics

Wire up your ultrasonic sensor like this picture. 

VCC is connected to the 5V Arduino pin 
Trig is connected to Arduino pin 3 
Echo is connected to Arduino pin 2 
Gnd is connected to an Arduino GND pin
Now that you have it wired, you are ready to type in the example code. 
Here is the code with descriptions of what each line does. 

Verify and upload the code to the board

Test it: Serial Monitor

After you upload it to board, see if it works. The text for how far away objects are from the ultrasound sensor is being sent to the serial monitor. To see that, you have to open the monitor by clicking its button. Here is where that button is and what the monitor looks like. 

Making the Arduino Light Up if you get to close

Put this right after the last code's Serial Prints. This makes the light turn on if distances are between 0 and 91 cm, otherwise the light is off. 

We also need to define the LED's location and to define that pin would as an output. Add that to the ultrasound code following this example. ​
We will now add a little bit to our code so that when you get closer than three feet to something, a light will turn on. Three feet is 91 centimeters, we need that number later. You can pick a different difference if you want. Every foot is about 30.5 cm. 

To do this, we have to add what is called a condition. This can be done with an "if/else" statement. 
Here is an example of an if/else we can add. ​

Example Wiring

The only thing we are adding is the LED to GND and pin 13. Depending on the color, you will need to add a resistor. The 220 or 330 Ohm resistor works well for Red or Yellow. Ask your teacher about how to do this if you need to. 

Full Example Code

Verify and Upload Code to the Board, Does it Work?  

Is the code working, what is happening? Ask your teacher for help if you need it. 

Trying the Buzzer

If you got your light to shine when you got too close to the sensor, then you can do the same thing with the buzzer instead.

Replace the light with a buzzer and see if it now buzzes when you get too close! 

After that works, use your breadboard by connecting a wire to GND to - and pin 13 to the + rail. Then you can plug as many lights and buzzers in parallel to the breadboard rail. See if you can control multiple things at once with the ultrasound sensor. Remember to use resistors for the lights.

Seeing your Heartbeat with Light! 

The color of blood

Have you ever heard that blood gets darker if it does not have oxygen in it? Well, that's true. The more oxygen blood has, the more deep red light it absorbs so it reflects less deep red. 
Picture
All sketches for this section come from this source: ​https://www.youtube.com/watch?v=MHPgamGQmDY

Graphing blood's light absorption by wavelength

This is a rough sketch showing how much hemoglobin (Hb) absorbs different light wavelengths  depending on if it is oxygenated.  

Red light at a 660 nm wavelength is used in pulse oximeters. This is because it is the max difference between light absorbance.

The Visible Light Spectrum

White light includes all primary colors (ROYGBV). Remember prisms from elementary school? This prism separates Red, Orange, Yellow, Green, Blue, and Violet from white light! I do want to point out, Violet does not mean purple! It is the "roses are red, violets are blue" color.
Violet is a flower. Click here to see some. https://en.wikipedia.org/wiki/Viola_(plant)
Picture source: ​http://blogs.nature.com/ofschemesandmemes/files/2015/02/Week-2-Blog-Dispersive-Prism.jpg

ROYGBV is just the visible light wavelengths! 

Light penetration

You can see red light penetrate through your finger if you put it in front of a flashlight. You see red on the other side because most of the other colors were absorbed in your finger. Try this at home! Put your phone flashlight, or any white flashlight, on one side of your finger. Then look at what color makes it to the other side!

Red light can be used to see inside your body.

Let's shine red light on it. Yep, it's darker where something is sitting. That means there is not good blood flow there.
​There is more deoxygenated blood in that spot.  
Click this button see what was taken out after surgery. ​Warning: somewhat graphic image. 

Measuring the Heart Beat

Here is a video that shows a similar sensor to what you will build. This way, you know what to expect. We will use a sensor to get a plot of our heartbeat. Specifically, the sensor measures the IR light going through/off your skin. As blood pumps, this value changes. 

Measuring Pulse

Pulse is one of the simplest and main resources healthcare professionals can use to know if something is wrong with you. This activity will help you learn basic Arduino wiring, how to read data from a sensor, and how to get information to display on your computer monitor. ​

Before we write the code, we need to get the library that runs the SpO2 sensor. 
In Arduino IDE:
  1. Go to Sketch -> Include Library -> Manage Libraries
  2. Type in “max3010x” into the search box
  3. Install/Download the “Sparkfun MAX3010x Pulse and Proximity Sensor Library”
Now we are ready to wire and code the sensor. ​

How to Wire the MAX Pulse Sensor

Flip over your sensor and find the 4 prong labels (Vin, SDA, SCL, GND). You will also need 4 wires to connect the sensor to the Arduino. Use the picture here to help. 

Vin (volts in) to the 5V Arduino pin. 
GND (ground) to the GND Arduino pin.
​SDA to the Arduino A4 pin.
SCL to the Arduino A5 pin. 

Coding for the Pulse Sensor

Here is Mr. Dorsey explaining the sensor and code

Verify and Upload the Code to the Arduino 

After you upload the code to the board successfully, open up your serial plotter.

Seeing your pulse data. Serial Plotter

and see if you see your pulse data. You will have to wait about 10 seconds for the graph to zoom in on the data. ​
Here is a screenshot of Mr. Dorsey's data from the serial plotter.
Here are some tips to get a good reading. 
1) Use your thumb, it is bigger and has more blood flow
2) Do not push down too hard on the sensor (that would restrict blood flow) 

Light blinks when your heart beats.

In this activity, we will turn on a light every time your heart beats. In order to do this, you need to set a "threshold value". That means an upper limit. Whenever your sensor gets a reading above that point and the graph goes above that point, the light will turn on. 

Under development

Supplies Needed

PIR Motion Sensor
Arduino and USB Cord
LED 

What is this sensor? It is a PIR Motion Sensor. 

PIR =Pyroelectric IR (infrared). Pyroelectrics make voltage when heated or cooled. IR light is really good at heating. It detects if incoming IR light, at the same wavelengths body temperature emits, is rapidly changing .

Yes, you emit light, even in the dark! This sensor detects changes in that light. Here is a picture from an IR camera. 
The white dome is a lens to focus light coming from all frontal directions to a central IR pyroelectric crystal. 
IR Light penetrates thin plastics

Displaying Text on a Screen. "Hello!" 

Supplies Needed

Arduino and USB Cable
OLED Screen
4 Pin/Hole Jumper Wire

Part 1: Downloading the OLED Library

Open up your Arduino IDE program. Then go to tools and manage libraries to get the following. 
Install the "Adafruit SSD1306" library. If it asks you to install other ones for it to work, say yes to getting all of them. 

Part 2: Wiring the OLED Display and Graphics Test

The Wiring. 
1) GND to GND 
2) VCC to 5 V
3) SCL to pin A5
4) SDA to pin A4
Download, verify, and upload this code.
This is a graphics test.

Did it work? If not, get help from your teacher. 

Part 3) The Code. Writing Text. Hello World! 

Type up this code to the right. 
After you think you have it, check it (verify) 
Upload it to board if that works and you have the screen wired correctly like the picture above. 

Did it work? 

If you got it to work, then play around with the text size, color, Cursor positions, and actual text you want to type.

Show your teacher if you make something really cool!

Disclaimer: The IR sensor for this activity is not medical grade. It cannot serve diagnostic purposes. If at any point you are concerned about your temperature, use a medical thermometer. If you are still concerned, consider consulting your family physician.

What you will need for this activity: 

Arduino/USB 
Arduino Wires
Infrared Sensor
OLED Screen
You should already have completed the regular IR Touchless Temp Sensor Activity. 
Use the button below to go to that activity if you need to look back at that activity. 

Wiring the Sensors

Both Sensors connect to the same part of the Arduino Board. Use jumper wires to connect one of them to the breadboard, and then put the other device's pins on the same breadboard rows.
The wiring for the sensors is as follows:
1) Vin to breadboard to 5V on Arduino 
2) GND to breadboard to GND on Arduino
3) SCL to breadboard to A5 on Arduino 
4) SDA to breadboard to A4 on Arduino
Both on their own
Example for Connecting Both

Coding for Two Devices

To code for two devices, you really should have done each one on its own successfully first. 
Here are buttons to take you to the independent lessons to check if you have already done them. 

Compare the Two Old Codes

Here are the two independent codes that we need to combine to get both devices to work. 
Hello World OLED Text Code
What are the main code sections in both? 
1) Before setup       2) Setup          3) Loop
Touchless Temp Sensor to Serial Monitor Code
We need to combine those 3 main parts to make this code work. 
I highly recommend loading up one of your old codes and then making a new save file. 
This way you are starting with something you know works, and then have less to add to finish this. 

An Example of Combining the Code

There are many ways we could combine these two coding examples to make it work 

"Calibrating" the sensor

Is your Serial Monitor displaying temperatures that are lower or higher than your actual body's temperature? If so, then you can calibrate the sensor by adding a "correction factor" to your code. 
I used a thermometer to check my temperature. Turned out it was 98.5 F but my sensor was reading about 5 too low :( 
To correct the reading by 5 F, I put +5 on the ObjectTempF row
Here are the the readings after the correction. ​

Display your Temperature on Screen

This lesson combines the code from the Hello World OLED screen lesson and the temperature sensor code. Here are links to those two activities so that you can go back to them if needed. 

Supplies Needed

Arduino and USB Cord
Breadboard
4.7K to 5.3K Resistor 
You likely have a 5.1K in your kit
OLED Screen
Temperature Probe
Jumper Wires

Reminding Ourselves of the Old Codes

We will use the basics of what we learned from coding the screen and temperature sensor to do this activity. We will be combining the two codes so that the LCD screen displays the temperature. Here is the old codes. 

Temperature Sensor Code

OLED Screen Code 

The Wiring

The wiring is combining the two together. Here is what they looked like on their own.
​Just do both together at the same time. 
Except plug the screen into the 3.3 V 
This is because the 5V will be used by the temperature sensor. 

Combine the Wiring

We need two things plugged into  5V? But fun fact, the screen can also run on 3.3 V!
Here is how to wire it. 
1) Screen's GND to Arduino GND
2) Screen's VCC to Arduino 3.3 V 
3) Screen's SCL to Arduino A5
4) Screen's SDA to Arduino A4

5) Temp probe's red wire to Arduino 5V 
6) Temp probe's black wire to Arduino GND 
7) Temp probe's yellow wire to Arduino pin 2 
8) Jump the 5k resistor from yellow to red row on the breadboard 

Combining the code

There are several main parts to the codes. The parts before the setup, the setup, and the loop.

We need to move these parts from one code to the other code. That will look something like this.
​
We do not need the serial begin any more though because we are only using the display  

Go Beyond!

Differentiation day: Students get time with teachers to catch up on activities from earlier this week if they could not finish them. Students that are ahead can try our optional lessons or look through tutorial books and learn how to do more at their own pace.
