I've been playing around with a couple of ESP32 microcontrollers, and that experimentation has taught me a lot about sensors and what you can build for really, really cheap. For as little as $4, you ...

When you think of "machine learning," you probably think of GPU clusters crunching terabytes of data, or at the bare minimum, the likes of a singular humble RTX 5090 being used for data processing.

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really small, like ...

The Raspberry Pi Pico is a microcontroller development board powered by the custom RP2040 chip. With its dual-core ARM Cortex-M0+ processor, extensive GPIO pins, and built-in programmable I/O (PIO), ...
