Hi, I want put a botton for reset the counter, but the way i did it went wrong. import RPi.GPIO as GPIO import time from espeak import espeak GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(26 , GPIO.OUT) GPIO.setup(20 , GPIO.IN) GPIO.setup(19 , GPIO.IN, pull_up_down = GPIO.PUD_UP) espeak....

I think it's related to this: " The input polyfuse may have tripped. It is self-resetting after it cools down and the polymer re-crystallizes, which can take several hours. Set the Pi aside and try again later." https://elinux.org/R-Pi_Troubleshooting#GPIO If that had happened then the Pi wouldn't ...

Is a cheap multimeter. But I did some tests, how: put buzzer, LEDs etc. However, Today, it comeback a working*. * If I use it a some and reboot, usually it doesn't working. So have i that shutdown it and wait maybe until it cools down. I think it's related to this: " The input polyfuse may have trip...

I already tested buzzer, LEDs, measured the voltage and nothing novelty.
Would there be any tests for me to check where the problem is?

Hi, I am using a Raspberry Pi 3B, I created some circuits using the GPIOs. Overnight, the pins are not working properly. For example, the 3.3V and 5V pins are not providing voltage. Everything else works perfectly, such as turning it on and off, accessing the internet, editing files etc. I think it ...

Olá, Eu estou usando um Raspberry Pi 3B, criei alguns circuitos usando as GPIOs. De um dia para o outro, os pinos não estão funcionando direito. Por exemplo, os pinos de 3,3V e 5V não estão fornecendo tensão. Em todo o resto ele funciona perfeitamente, como ligar e desligar, acessar internet, editar...
