Read and Control with the Same Board!
This Analog to Digital Converter allows you to read voltage levels from 0-5 volts using 8-bit or 12-bit resolution. This is particularly useful for reading temperature sensors (one temperature sensor is built into the board, shared with analog input number 8). A/D Inputs are also useful for reading light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of. Built-In Pull-Up/Down Resistors keep the inputs quiet.
