Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

This project utilizes an Arduino Nano along with an ultrasonic sensor to create a distance-based LED color changer. The objective is to demonstrate how the color of LEDs changes based on the proxim ...

This Arduino-based distance meter can be used for measuring the distance between the sensor and object in the range of 2cm to 400cm.

As many Arduino enthusiasts will tell you, they have a million ideas for projects but haven't completed nearly as many as they want. Here are some of the best Arduino projects we have found.

The circuit is built around Arduino Uno (MOD1), ultrasonic sensor HC-SR04 (S1), HC-05 Bluetooth module (MOD2), buzzer (B1), and LEDs. The ultrasonic sensor is used to maintain proper distancing, and a ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...
