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.

But by the age of nine, a noticeable gap begins to emerge — girls’ confidence and enthusiasm for STEM subjects often start to ...

One of Arduino's biggest strengths is the ability to attach sensor shields to a board. Most shields fit the UNO, but some enterprising companies such as Keystudio make shields for larger boards ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Learn how to create a simple heart rate monitor using an Arduino Pro Mini, PulseSensor, and OLED display. This ...

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’, ...

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.

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...
