IDM 382: Internet of Things
Fall 2020
Over the past 11 weeks, I worked on developing a device using the Internet of Things to be able to control a series of NeoPixel lights using a web browser in order to promote the use of technology to better the fundamental developmental growth of early childhood education. Through this project, I not only learned about the educational benefits that colors bring to a child’s education but also the process of understanding how to wire breadboards and work with Arduino without short-circuiting any equipment. I learned how to use a variety of different tools to reach my goal of working on my device online and how to adapt my code to each program.
Goals
- TrackAllow online access from online dashboard to control LED lights
- Debug problem with sticky buttons
- Debug problem where clicking onto one button
Final Presentation
Future Plans
- Seeing if it is possible to attach a projector to the Arduino
- Developing an interactive story book projector that reacts to the buttons that are pressed using IoT
Sample Code
void loop() {
ArduinoCloud.update();
// Your code here
//Serial.println("looping");
for(int i=0;i<NUMPIXELS;i++){
// pixels.Color takes RGB values, from 0,0,0 up to 255,255,255
pixels.setPixelColor(i, pixels.Color(redColor, greenColor, blueColor)); // Moderately bright green color.
pixels.show(); // This sends the updated pixel color to the hardware.
delay(delayval); // Delay for a period of time (in milliseconds).
// Serial.println(i);
}
} // END LOOP
void onLEDbuttonChange() {
// Do something
}
void onButton1Change() {
// Do something
Serial.println("virtual button click");
lEDbutton = "Button Color 1 Pushed";
noColor();
} // End Here
void onButton2Change() {
// Do something
lEDbutton = "Button Color 2 Pushed";
setColor();
} // End Here
void onButton3Change() {
// Do something
lEDbutton = "Button Color 3 Pushed";
setColor2();
}
void noColor() {
redColor = 0;
greenColor = 0;
blueColor = 0;
};
void setColor(){
redColor = 0;
greenColor = 255;
blueColor = 255;
Serial.print("red: ");
Serial.print("green: ");
Serial.print("blue: ");
};
void setColor2() {
redColor = 255;
greenColor = 0;
blueColor = 255;
};
