GPIO.FALLING INSANELY! sensitive - Raspberry Pi Forums

i had shutdown python script connected gpio pin using gpio.falling. long time getting seemed random shutdowns. started notice turning light switch on , off, turning ceiling fan on or off, , using electric lighter near trigger pi shutdown. switching high or low read of pin solved issue. there way use gpio.falling without being sensitive outside interference? setup: gpio.setmode(gpio.bcm) gpio.setup(17, gpio.in, pull_up_down=gpio.pud_up) wire connected pin 17 connect ground pin when wanted shutdown. thank help. are using pull resistor? try 10k. raspberrypi

Interrupt for measuring time

Image
hello guys, i have tried find suitable had no luck far that's why approach since last hope i have got electrical engine , want measure frequency runs. rotational meter creates rectangle current. want count how there rise in current , want measure time between 2 flanks. but have no idea how overall structure looks like. can please me? you can use interrupt triggered when pin goes low high (voltage) , then, measure time. code: [select] unsigned long lasttime; unsigned long period; void setup() {   attachinterrupt(0, measurefrec, rising);  // arduino pin 2 } void measurefrec() {   unsigned long time;     time = millis();  // beware overflow!!   period = time - lasttime;   lasttime = time; } Arduino Forum > Using Arduino > Programming Questions > Interrupt for measuring time arduin...

Using LEDs

Image
i using hall effect make led turn off.  when magnet approaches hall effect, led turns off.  there way sense when led turn off (stop lighting up) other seeing led off?  guess want program check current state of led. well...   you using arduino in-between hall-effect sensor , led, right?  in case, program (sketch) "knows" if led on or off, since, it's thing turning on/off . if that's not set-up, can connect either hall-effect output, or led-circuit 1 of arduino input-pins, , sketch can read input.  (you need "match" voltages, might need see schamatic.)
