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.
