I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless control to Arduino or ESP8266 projects. In this video, I’ll walk you through ...

It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

When I wrote about a DIY ESP32-S3 internet radio last week, "raspbeguy" commented he'd rather choose an ESP32-based DIY DAB+ ...

Flash Bee is an easy-to-make DIY handheld lightning detector based on an ESP32-C3 board, a round display, and AMS AS3935 ...

Espressif has released the ESP32-H21, a low-power wireless SoC aimed at Thread, Matter, Zigbee, and Bluetooth LE device designs. The new device is positioned as an incremental update to the ESP32-H2 ...

Abstract: Safe and reliable signal transmission across different power domains is critical in high-voltage electronic systems. Analog isolation amplifiers are key in achieving galvanic isolation and ...

The Texas Instruments CC1101 is a very versatile, high quality and cheap transceiver, supporting a wide range of frequencies and modulations. Ready-to-use CC1101 modules are as cheap as 5.00€ and at ...

Environmental analog sensors—such as Light Dependent Resistors (LDRs)—produce inherently noisy and fluctuating voltage signals. When interfacing these raw analog signals directly with digital ...
