By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, ...

After making the circuit ready, it’s the time to go ahead with designing our PCB using the PCB design software. As stated earlier we are using EasyEDA PCB Designer, so we just need to convert the ...

Contains the 2D layout of the board with Arduino Nano's standard size as well as the routing, alignment, and guide comments.

There are few open source HW board available supporting the SW either designed as shield on top of Arduino Board or stand alone board (all in one board) In the repository you can find my personal ...

Here we outline how to construct a simple and reliable Flame-Sensing Fire Alarm System using an Arduino Nano board. This fire alarm is intended ... 2 presents the circuit diagram for the fire alarm ...
