This project is based on Arduino UNO and an ultrasonic sensor. It is designed to measure distance and trigger a buzzer if the measured distance is below a certain threshold. The ultrasonic sensor ...

Slave: Measures distance using an ultrasonic sensor and sends the data via I2C. Master: Receives the distance data, stores the last 10 readings in a simulated EEPROM, and can display stored data via ...

[Kevin Osborn] is making it a bit easier for young programmers to write programs that interact with the physical world. The device he’s holding in the picture is an Arduino based accelerometer and ...

If you’ve always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your ...

This system demonstrates water level and temperature monitoring on a 10.92cm (4.3-inch) TFT LCD using graphics and ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...
