This circuit uses a breadboard, a red LED, a 150Ω Resistor, a few wires and an Arduino card. To blink the LED I need a C++ Program :
// Project 1 - LED Flasher
int ledPin = 10;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
and now a result of this program can be seen in this video:
