ACS712 Current Sensor with Arduino The ACS712 is a popular Hall-effect-based current sensor that provides accurate current measurements in both AC and DC circuits. It is widely used in electronic ...

This is an Arduino project using an HC-SR04 Ultrasonic Sensor and LEDs to measure the distance of objects, similar to a scale. When an object comes close to the HC-SR04 ultrasonic sensor, it indicates ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. The ...

I have made considerable progress on this project. I withdraw my initial assessment that this is a dead end. Read on. A friend is very involved with the support of local walking trails. His group ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

This trail use counter is so different in design from my original submission that I decided to resubmit the project. A couple of months ago, I submitted a project designed to use a laser beam ...
