(This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest. Another note is the () must be used properly and in sets of 2. void loop() { if ( S1() ) { byte temp = digitalRead(LED1); temp = !
This example shows how to fade an LED on pin 9 using the analogWrite() function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins ...
