Test the board!
UNDER NO CIRCUMSTANCES will troubleshooting help be
offered if you have skipped this stage. No exceptions.
Once you’ve finished the circuit it makes sense to test is before starting on
the switch and LED wiring. It’ll cut down troubleshooting time in the long run.
If the circuit works at this stage, but it doesn’t once you wire up the switch -
guess what? You’ve probably made a mistake with the switch.
Solder some nice, long lengths of wire to the board connections for 9V, GND,
IN and OUT. Connect IN and OUT to the jacks as shown. Connect all the GNDs
together (twist them up and add a small amount of solder to tack it). Connect
the b lead to the 9V wire, same method. Plug in. Go!
If it works, crack on and do your switch wiring. If not... aw man. At least you
know the problem is with the circuit. Find out why, get it working, THEN worry
about the switch etc.
