There are several cheap sensors that can help you build incredibly versatile devices without spending a lot. And, you won’t ...

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 ...

Soon to be launching via Crowd Supply is a powerful ESP32 based IR/RF remote taking the form of the aptly named ESP360 Remote. The small open source hackable IR and RF remote features 9 IR LEDs and an ...

The ESP family of microcontrollers is absolutely on fire right now, with a decent chunk of the projects that come our way now based on one of the impossibly cheap WiFi-enabled boards. In fact, they ...

Christopher Robertson has created a new 3D printer filament roller and feeder which offers an all-in-one IR sensor and alarm to detect all filament feeding errors automatically to help stop your ...

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the chip, and its ESP32 data sheet has nearly no mention of the Hall sensor ...
