How to use analog sensors with the Arduino?

Use analogRead (pin) method to read the signal from an analog input. STEP 1: Connect sensor. Some sensors are supplied in the form of modules with a pin which can be connected directly to an analog input Arduino. Others are resistive sensors that you need to merge with a resistor in order to read its value. STEP 2: Download the test code
