These are some great DIY projects that you can do for cheap.

The SparkFun MCP4725 Arduino Library provides full control over Microchip's MCP4725, a 12-bit single-channel I2C digital-to-analog converter (DAC). The MCP4725 is compatible with SparkFun's Qwiic ...

Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s time for something fun. It’s time to turn your skills into entertainment ...

The ESP32-C6 doesn't look like much at first glance. It’s small, cheap, and the kind of thing I tend to lose in a drawer. But if you look closer, you'll find a tiny board that packs almost everything ...

This IoT-enabled system continuously tracks a bedridden patient’s vital signs (ECG waveform, heart rate, and body temperature) from anywhere in the world. By combining a microcontroller (Arduino) with ...

This ADC calculator takes analog input and provides a digital output given the Number of bits, Analog Voltage and Reference voltage. Microcontrollers can only handle binary signals. A microcontroller ...

The DFRobot Fermion: C4002 mmWave Radar Module features a Full Data Access Mode that provides developers with processed micro-Doppler telemetry and displacement vectors. Why do smart home systems ...

We cover so many projects here at Hackaday that lead the author down a rabbit hole of technological investigation that distracts us from the task of bringing them to you. Such a project is ...
