Bluetooth started as a simple cable-replacement idea in the ’90s — today it powers everything from wearables to IoT sensors.

I just read a great deep-dive on using Bluetooth Low Energy with the CH32 series microcontrollers and the CH9141K module. It walks through wiring, USART remapping, AT-command setup, and sending real commands over a wireless serial link.

If you're building embedded or IoT projects and want an easy way to “cut the cable,” this guide is worth a look.

The Evolution of Bluetooth: How We Got Here Bluetooth started in the early 1990s as a surprisingly modest idea: replace clunky serial cables. Engineers wanted a simple wireless bridge between devices, something that could stand in for RS-232 without adding complexity. What happened next was far bigger. Over the years Bluetooth gained higher d...

Smarter Ways to Handle Buttons in Electronics Design

When your project needs more than one button, wiring can quickly get messy. Should you go for direct GPIO connections, matrix wiring, I/O expanders, or something more creative?

Our latest blog post breaks down different methods for wiring buttons in embedded projects and introduces a particularly clever approach featured by Curious Scientist: using an analog input to handle multiple buttons with just a few components.

It’s a practical look at how to keep your wiring clean, save pins, and design smarter input systems, whether you’re building a simple controller or a production-ready device.

Different Ways to “Button” Your Project Every project eventually needs a way to interact, and sooner or later, that means buttons. But wiring buttons can be surprisingly tricky, especially when you want more than a couple. There are several ways to do it, each with its own strengths and limitations, depending on how many inputs you need a...
