complete kit from www.thonk.co.uk. It also assumes no previous knowledge
of electronics. To learn to solder try
Adafruit guide to excellent soldering –
Watch and understand that whole YouTube video! If you're not achieving the
results shown in the video then you need to buy new tools or seek advice.
You will not end up with a working module otherwise.
TOOLS REQUIRED
Soldering iron, snipe nose pliers, wire strippers, small flat head screwdriver
and diagonal cutters AKA snips AKA side-cutters. A Digital Multimeter is
necessary for calibrating this module accurately but you can do it by ear to
