Make LED light up from serial monitor - Programming Questions - Arduino Forum

I want to controll red diode with a comand, blue diode with a comandand same with green. 3 different if statements. I want it as basic as possible so I can understand the code const int RED = 9; const int GREEN = 8; const int BLUE = 7; void setup() { pinMode(RED, OUTPUT); pinMode(GREEN, OUTPUT); pinMode(BLUE, OUTPUT); } void loop() { digitalWrite(RED, HIGH); digitalWrite(GREEN, HIGH); digitalWrite(BLUE, HIGH); }
