From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

Overview This project demonstrates how to control the brightness of an LED using a potentiometer (analog sensor) with an Arduino. The potentiometer’s value is read by the Arduino and mapped to control ...

This project monitors voltage using a potentiometer connected to an Arduino. When the voltage reaches 4.8V or higher, the system automatically sends an SMS and makes a phone call using the SIM800L GSM ...
