Arduino Based Real-Time Oscilloscope The Oscilloscope is an essential instrument for the workbench of every electronics engineer or maker. It is primarily used for monitoring waveforms and analyzing voltage levels, frequency, noise, and other signal characteristics that can change over time at its input. Embedded software developers utilize it for code debugging while technicians depend […]

LDR Robot with IR and a Servo The LDR/IR Robot is designed to seek out light and avoid obstacles. The robot uses the Light Dependent Resistor to seek out light and the Infrared Sensor to detect and avoid objects in its path. The following are instructions with pictures to show exactly how we built our

A light-dependent resistor (LDR) whose resistance is inversely proportional to the intensity of light is often used as a sensor in electronic projects that involve the use of light. This LDR based DC motor speed control project uses an LDR to control the speed of a DC motor. The objective of this project is to

In this article we are going to make a Solar Panel Tracker using Arduino, in which we will use two LDRs (Light dependent resistor) to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light. Advantage of this project is that Solar panel will always
