So possible errors with your circuit. 1. Feeding chip from 6v means you need 4.2V input to be seen as a high input ( pi gpio is 3.3V ). 2. There does not appear to be a ground from the pi connected to your bread board. 3. There does not appear to be a current limiting resistor in the LED circuit. 4...

I am having problems trying to light a led through batteries by giving the signal with my raspberry pi 3B+. This is my current setup. The chip is 74HC08. Doesnt matter if i set output to 1 or 0, the led randomly turns on and off. I even connected the led+ to raspberry GND or 5V but still absolutely ...

Any update on this? Iam also having this problem, suddenly my raspberry pi 3b+ wont boot. 3V3 pins not outputing any voltage, while 5V works fine and i use the official power supply.

I bought a raspberry pi 3B+ some months ago and it worked perfectly for some time. All of a sudden it didnt boot 4 days ago, so i burnt a new raspbian lite image in the sd and the problem persisted. I bought a new sd and again burnt the latest Raspbian Buster Lite and plugged in my pi with the offic...
