Powering an Arduino has a little magic to it. It wasn’t obvious to me when I first started working with them, but Arduinos have on-board regulation. Taking advantage of this allows for longer power ...

I'm trying a new switch board using an Arduino board. The only issue is I have more switches which required the 'power' supply than female ports available on the board. I understand the way around ...

You can use this solution as a Power Supply Unit controller for Raspberry Pi, Terasic DEx boards or any other SoC projects requiring external power. Initially this project was developed as a part of ...

The circuit above is composed of a 220V to 12V PSU and a 12V to 5V switching power supply The measured output is ~5V. I've connected the ESP to a 5V power source. If I boot up the ESP without ...

USB-C Power Delivery 3.0 (PD3.0) introduces a new Programmable Power Supply (PPS) mode, which allows a device to negotiate any supply of 3.3-21 V in 20 mV steps, and up to 5 A of current in 50 mA ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...
