Please refer to the picture attached.
When the switch closes the circuit, the buck converter at the bottom of the image turns on (as expected) and the code I have running in the Raspberry Pi detects a low signal going into the Raspberry Pi pin the transistor's emitter is connected to (also as expected). Now here's where things get really confusing for me...
When the switch opens the circuit, I expect the buck converter at the bottom of the image to turn off, but it doesn't! Can someone...
I fried a Raspberry Pis and I have no idea why. Please help me understand.
