keyboard - How can I use a toggle switch as a momentary switch on my arduino? -
i have specific switch need use , happens toggle. problem is, need send keyboard stroke computer time button pushed on or off. tried 1 modification of basic example on arduino website, isn't working me:
const int buttonpin = 2; // number of pushbutton pin int prior = 0; int buttonstate = 0; // variable reading pushbutton status void setup() { pinmode(ledpin, output); pinmode(buttonpin, input); keyboard.begin(); } void loop() { prior = buttonstate; buttonstate = digitalread(buttonpin); if (buttonstate != prior) { keyboard.write(32); } }
you can debug issue breaking 2 part. first debug whether able toggle of switch can switch led on/off whenever toggle switch (assuming leds working fine) in loop. once done. debug keyboard.write() send characters pc @ fixed delay may 1sec in loop. if both working fine above program might work. try adding delay after keyboard.write().
