Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

Raspberry Pi also has a broader selection of I/Os, such as an audio jack, more USB ports, and more. And with 40 general-purpose I/O (GPIO) pins, you can even daisy chain multiple Raspberry Pis ...

A Visual programming language called ArViz is proposed in this work. ArViz is an extension of Ardublockly and senseBox Blockly, which are based on Google Blockly. ArViz is designed as a visual ...

The hooter connects to the normally-open (NO) contacts of the relay. When the flame sensor detects a flame, it triggers two actions: the three LEDs light up for visual indication, and the hooter ...

The Arduino Plug and Make Kit provides a 10-minute, cloud-based IoT solution that includes QWIIC and smartphone-based sensors, transducers, and actuators.

MechDog open-source robot dog supports Arduino, Scratch, and Python programming, allowing versatile project development. You can attach various sensors to enhance its perception and AI capabilities.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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.

It’s a simple matter of hooking up the Grid-EYE sensor to the Arduino Uno over I2C, and then spitting out the sensor’s data in a nice visual form on a cheap TFT screen.
