Open Chess project delivers electric shocks for bad moves and costs $22 versus $600 commercial smart boards through open-source DIY design.

BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

In this series I will be documenting my design and testing process for making a 3D printed arduino hexapod. This video sets up the basic premise of the project with a quick test of a servo controlled ...

A hackerspace is a place that generally needs to be accessed by a wide group of people, often at weird and unusual hours.

Arduino, supported by Qualcomm, is partnering with Indian edtech firm Get Set Learn to introduce on-device AI and robotics learning across India's K-12 school system.

The collaboration will help students learn by building real, intelligent devices that run AI locally, reducing reliance on the cloud and making the learning more practical for real-world use.

The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...
