What does this kit do?
Build a circuit that sets off an LED for a period of time. When you press the button, the LED changes from red to green and turns back to red after the time you set between 1 second and 4 minutes. The kit uses a 555 timer chip for the timing and a variable resistor (or potentiometer) to change the timing. Time a perfectly boiled egg or set up your own game of countdown with timed rounds – simply set your time and hit the switch.

What is in the kit?
This kit is fun and simple to solder – a great way to see how components work with each other. Get experience soldering resistors, potentiometers (variable resistors), capacitors, IC holders and a tri-coloured LED. This kit works by using a 555 timer chip that you can set by altering the resistance of the corresponding variable resistor. This kit requires soldering and may require wire cutters, a screwdriver and wire strippers (not included).

How easy is it to solder?
Perfect for beginners, this kit is easy to solder. It’s also a great introduction to 555 timer chips which are used in more complicated circuits. Once you’ve built the kit you may want to build an enclosure to protect it (not included), just take care not to block the switch or buzzer. This kit requires two AA batteries (not included).
