KiCad Electronic Circuit Design - Part 1 Eeschema Schematic Diagram - Model Railway Traffic Lights

Описание: This video goes through the process of designing an Arduino like electronic circuit using KiCAD (Free Open Source circuit design software). This is a guide to creating a printed circuit board for my garden model railway traffic light which I 3D printed after designing in FreeCAD.

I've already explained how it can be controlled using a Raspberry Pi Pico
   • Raspberry Pi Pico - Model Railway Traffic ...   but I wanted to create my own custom printed circuit board.


This circuit is based around the ATmega328P, which is the same microcontroller used in the Arduino UNO and similar boards. As long as the Arduino bootloader is installed then this can still be programmed in the same way as the Arduino using the normal Arduino IDE.

In this first part I show you how to create a schematic diagram using Eeschema. Then in part 2 I will show how you can turn that design into a printed circuit board which can be manufactured by a PCB fabrication company.
