Test the board!
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.
