Description: A micro slide switch turns six LEDs ON/OFF. No resistor is needed, since with a resistor either not LEDs would turn ON or they would be dimly lit due to not enough power from the Nerdonic Exen Mini.
Supplies:
1 – Breadboard 400 Points
1 – Nerdonic Exen Mini
6 – LED
1 – Micro Slide Switch
Arduino Code:
#define switch SCL
#define led SDA
#define led2 0
#define led3 1
#define led4 A2
#define led5 A3
#define led6 A4
int switchState = 0;
void setup() {
pinMode(switch, INPUT_PULLUP);
pinMode(led, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
pinMode(led4, OUTPUT);
pinMode(led5, OUTPUT);
pinMode(led6, OUTPUT);
}
void loop() {
switchState = digitalRead(switch);
if (switchState == LOW) {
digitalWrite(led, HIGH);
digitalWrite(led2, HIGH);
digitalWrite(led3, HIGH);
digitalWrite(led4, HIGH);
digitalWrite(led5, HIGH);
digitalWrite(led6, HIGH);
}

digitalWrite(led, LOW);
digitalWrite(led2, LOW);
