The complexity here is that we need to fix the circuit in a mobile and remote place—the helmet. So, simplifying the circuit is most important to make it compact and reliable. The circuit diagram is ..

Most of us learned to design circuits with schematics. But if you get to a certain level of complexity, schematics are a pain ...

With its isolated circuits, long-cable safety, and smart Ethernet, WiFi, and Bluetooth combination, this system ticks every DIY box. Hackaday has featured other DIY PoE-powered projects ...

In this session, you'll assemble a multiple electronic circuits around an Arduino microcontroller including lights and sensors. You'll learn how to tell such a microcontroller what you want it to do!

Abstract: A carefully planned schematic diagram will simplify the study and servicing of electronic equipment. Whereas a conventional schematic merely shows the electrical components and how they are ...

This is a simple and practical implementation of an RFID-based attendance system using Arduino. It uses the MFRC522 RFID module ... the system marks the user as "Present" and displays a message on a ...
