Hi Guys
I have a project where i need to interface some sensors with a microcontroller. However the micro runs off 3.3V and so does one of the sensors. However one of the sensors is 5V and gives a voltage output that I need to read in via the microcontroller ADC. Could anyone suggest a way of interfacing this sensor? The microcontroller pins are not 5v tolerant and the only way I could think of doing this would be to do a potential divider but wasnt sure if this would be accurate enough. Hope someone can help
