Any news in the maker hobby concerning Raspberry Pi, ESP, Micro:bit, or any other mainstream projects that we think you should hear about.
With summer soon approaching and bringing rain and lightning with it, this sensor makes for a useful project. The WS16 AS3935 lightning sensor is a handy little board housing the AS3935 chip along with a tiny little antenna – this pairing allows us to detect nearby lightning strikes up to […]
Using opto-isolated relays to control large devices with small 3.3V signals. We previously wrote about how to shift voltage levels here. That article solves a common problem: your MCU (microcontroller) or SBC (single-board computer, think Raspberry Pi) needs to talk to another device, but the two use different voltages — […]
