There is a power source of 75V and I want my Arduino to acknowledge when a switch has been activated. Such as when a switch closes it can read that it has been closed and perform a certain action. Is ...
There are 2 line followers, TCS3200, and a Bluetooth module, they are all powered with 5volt source, can I power them all with the 5-v pin in an Arduino Uno? Will it take a lot of current or burn the ...
I'm using 1206 0Ω resistors as jumpers, I added them in pcbnew not in the eeschema, pcbnew is asking me to connect the resistor pads together! It is a resistor! Any way to fix that?
I'm curious where should I apply this voltage? If it will change the threshold voltage, but I can't work out where you would attach a wire to for the body terminal of a MOSFET when they only h...
I'm trying to implement an LCD driver. All my pins have been initiated as GPIO output mode. My question is, how do I read a data if all of the GPIOs are in output mode? I mean, we can always chang...
What is negative resistance, how is it related to oscillators?In my understanding, it's something to do with decreasing current vs increasing voltage. Is it a necessary condition for oscilla...
I have a 12V relay that I want to be able to energize with two inputs. These inputs might be on individually, or both at the same time. And they must be isolated from each other completely. How can I ...
I have a problem with bumping the usb cable that powers my RPI3B+ and it wiggles out and kills power. I was curious if I could cut off the USB end, solder those two wires to female GPOI connectors and...
