Wifi Serial

A project log for Arduino Mega Expansion board

A mini shield-like add-on for the Arduino Mega designed to add wifi/Bluetooth connectivity and more alongside the standard Uno-sized shield.

So, delivery #1 of many arrived today; 3 ESP07-based serial boards.

With only Tx, Rx, power and ground pins broken out, this board is controlled via AT and over a serial connection.

This is perfect for this project - added to the Serial1 port of the Mega it will make wifi comms easy!

I am going to adapt the Arduino sketch of the project I previously shared to process an 'ESP_' command, and forward the following string (which will be the AT command) straight to Serial1.

In addition I am going to write a python based GUI, along the lines of the previous link's C# application. This is to practice writing python GUI apps, and also to write something that works cross platform.

Will post my results Tommorrow, all being well!
