- Introduction - Electronics schematics + PCB Layout - Arduino Code - Application

This project was under development during the first semester of Master's Studies at Warsaw University of Technology (Poland) as a final project for Industrial Communication Protocols. Using the UART adaptation of RS-232, a simple controller was created. Its main goal was to make it possible to control a flow of mains current to the load devices. The device contains of two relays for bi-stable control and one triac for more "analogue" control (e.g., a lightbulb dimmer). The heart is an Arduino Nano board.

34 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mains-Voltage-Device-Controller design files?

From the kkorzen/Mains-Voltage-Device-Controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mains-Voltage-Device-Controller design in my own project?

Yes, under the terms of its MIT license, which kkorzen chose for the repository.

Can I test firmware for the Mains-Voltage-Device-Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
