Mixing voltage levels is one of the most common headaches in embedded work. Your microcontroller runs at 3.3V, the sensor you want to use is 5V, the display module next to it is 1.8V, and the old Arduino shield in your drawer still expects 5V logic. Connect them directly and in the best case nothing […]
