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 ...

Arduino Uno: The microcontroller that will process the data from the DHT11 sensor. DHT11 Sensor: A digital sensor capable of measuring temperature in the range of 0°C to 50°C with an accuracy of ±2°C, ...

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 ...

So in this project a basic vibration sensor module is interfaced with Arduino UNO and whenever the vibration sensor detects any vibration or jerk an LED will start blinking.

At its heart is an Arduino UNO, which syncs the RGB LED ‘bubbles’ and a servo-driven aiming arm to the game’s real-time data.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

This smart stick using Arduino can be a huge help for the visually impaired. It uses ultrasonic sensors for obstacle detection.
