One of the aims in making the circuit was to try and reduce the size as most as possible. I had to if I wanted it to fit inside a small case such as the flashlight case that I used in this project. Because of this I decided not to solder the capacitors connected to pin 2 to the prototype board but directly to the SPDT switch.

Steps:

1. Solder the positive legs of the 100uf cap to the first pin on the switch, the 220uf to the middle pin and the 330uf cap to the last pin

2. Do the same again for the other caps for 555 timer 2. There are different cap values for this timer - you just need to make sure that they are connected in descending order, 10k 22k and 47k

2. For each switch, connect all of the ground legs of the caps together. These will be connected to pin 2 on 555 timers later on

3. The other pins on each of the switches can also be connected together. These will be connected to ground on the prototype board later.
