Digital write and digital read are two different functions in programming for microcontrollers. Digital write is used to send a digital signal to a specific pin on the microcontroller, setting it to either high (5V) or low (0V). On the other hand, digital read is used to read the current state of a specific pin on the microcontroller, returning either a high or low value. In summary, digital write is used to output a signal, while digital read is used to input a signal. **
