Arduino Analog Input and Output Pins
Understanding The Arduinos Analog Pins Arduino's analog input and output pins are a crucial part of the platform, allowing you to read analog voltage levels from various sensors and devices. The Analog pins are A0 to A5. First thing you need to understand is the analogRead() and analogWrite() functions do NOT read and write the same thing. The analog read function reads a voltage value which is then converted to an analog value. The analog write function writes a PWM…
