Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

Aiming at sensor fusion application development, Rutronik has created a single Arduino-compatible board with a plethora of sensors from Infineon, Bosch SE and Sensirion. Called ‘RAB1 – Sensorfusion’, ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

The Arduino 101 has the same dimensions as the Arduino Uno, and the pins are compatible. You can stick shields designed for the Uno on the 101. While the optimum voltage for the 101 is 3.3v, the ...

As electronic devices got more complicated in the past few decades, it became increasingly difficult and expensive to tinker with hardware. The 1970s garage engineers who built their own computers ...

The MEAS weather shield with five environmental sensors on an Arduino/Genuino 101- and Uno R3-compatible board from TE Connectivity is available from Mouser Electronics. The five sensors are: the TE ...
