RGB Human Circuit

When you touch the leads on this circuit it flashes Red, Green, and Blue.

This Circuit was collaboratively built by Me and my Friend Cass.

Step 1: Gather Your Parts

You will need:

Breadboard

Breadboard Wires

Arduino (needs 4 I/0 pins

NPN transistor

3 leds (red, green, blue) or and RGB led

3 560R Resistors

1 10k Resistor

Step 2: Build Your Circuit

Here Is a link to the Schematic:

Step 3: Program the Board

Here is the program:

int readPin = 10;
int ledR = 9;
int ledG = 8;
int ledB = 7;
void setup(){
  pinMode(readPin, INPUT);
  pinMode(ledR, OUTPUT);
  pinMode(ledG, OUTPUT);
  pinMode(ledB, OUTPUT);
}
void loop(){
  
  while(!digitalRead(readPin)) {
    digitalWrite(ledR, HIGH);
    delay(50);
    digitalWrite(ledR, LOW);
    digitalWrite(ledG, HIGH);
    delay(50);
    digitalWrite(ledG, LOW);
    digitalWrite(ledB, HIGH);
    delay(50);
    digitalWrite(ledB, LOW);
  } 
}
