I am using a RPI zero to receive some data from sensors. All these sensors use 3.3V supply.
A teacher gave the idea of using the GPIO pins(not the VCC's itself) to supply power to the sensors, so that I'd be able to turn on and off the devices when I want to. It seems to work for some sensors, but others are working only sometimes.
That raised a question to me, is this a bad practice thing?..to use the GPIO pins (like pin 40) to supply power to other devices.
