This was one of the first programs i wrote for the arduino after having it a few days 🙂
we will be making l.e.d police lights with minimal materials
Step 1: You will need.
You will need
Arduino (or suitable clone)
Breadboard
2x 240ohm resistors
1x Clear Red l.e.d
1x Clear Blue l.e.d
Some Jumper Cables
Step 2: Place Components Onto Breadboard
Place the components onto the breadboard as the diagram shows
Step 3: Writing The Code.
The code for this project is very, very basic
// Project 1 – Police Lights by Dave1324
int ledDelay = 50; // delay by 50ms
int redPin = 9;
int bluePin = 11;
void setup() {
pinMode(redPin, OUTPUT);
pinMode(bluePin, OUTPUT);
}
void loop() {
digitalWrite(redPin, HIGH); // turn the red light on
delay(ledDelay); // wait 50 ms
digitalWrite(redPin, LOW); // turn the red light off
delay(ledDelay); // wait 50 ms
digitalWrite(redPin, HIGH); // turn the red light on
delay(ledDelay); // wait 50 ms
digitalWrite(redPin, LOW); // turn the red light off
delay(ledDelay); // wait 50 ms
digitalWrite(redPin, HIGH); // turn the red light on
delay(ledDelay); // wait 50 ms
digitalWrite(redPin, :LOW); // turn the red light off
delay(ledDelay); // wait 50 ms
delay(100); // delay midpoint by 100ms
digitalWrite(bluePin, HIGH); // turn the blue light on
delay(ledDelay); // wait 50 ms
