This will guide you on how to play musical notes of any song on a piezoelectric buzzer, using Arduino Uno R3, a resistor and some connecting wires.

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

If you’ve done 3D printing, you’ve probably at least heard of Tinkercad. This popular CAD package runs in your browser and was rescued from oblivion by Autodesk a few years ago. [Chuck] recently did a ...

Electronic systems can help the visually impaired. This innovative project combines an Arduino Nano, a TCS34725 color sensor, and a buzzer to assist users who have trouble seeing colors. How can a ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
