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 
taste. Thonk sell a range of inexpensive tools here -
