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.
