Electric Drills

Electronics

Joining Methods

Soldering (With Components & PCB)

Screws (Need Drill (Need power outlet)) (To secure PCB to wood)

Components

PCB (Printed Circuit Board)

Jack Wire

LED light for on/off

Switch

Efficiency

Don't waste wire with too much. Measure correctly. Also with soldering - don't use too much tin. This will waste energy (power outlet) & Materials

LED light used to symbolise current flowing through curcuit if switch is on or off. This is used to stop battery wastage, as battery replacement is costly.

Measurements (Also linked with 'Environment')

Need to be precise to stop wastage
