With just an Arduino board, a DHT11 sensor, and an I2C LCD, you can create a simple yet effective weather station at home. This beginner-friendly project displays real-time temperature and humidity ...

From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

In this DIY project, we’ll build a super-compact H-bridge motor driver that mounts directly onto the N20 motor itself. No ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

We had already seen OpenClaw-like AI agents for ESP32 targets such as Mimiclaw and PycoClaw, but Espressif Systems has ...

Waveshare UGV Beast is an off-road robot with tracked wheels designed for Raspberry Pi 4 or 5 SBC handling AI vision and ...

Gesture control robotics replaces traditional buttons and joysticks with natural hand movements. This approach improves user interaction and reduces mechanical dependency on physical controllers.

Space vector modulation (SVM) is a sophisticated digital control technique that improves three-phase inverter performance over traditional sinusoidal PWM (SPWM). SVM’s higher DC bus utilization ...

In a deal that surprised some industry observers, chipmaker Qualcomm has agreed to buy Arduino, which is best known for supplying microcontrollers to the DIY community. The acquisition, whose terms ...

Simple linear and switching voltage regulators with feedback networks of the type shown in Figure 1 are legion. Their output voltages are the reference voltage at the feedback (FB) pin multiplied by 1 ...

I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...
