• Set an alert for any time between 10 minutes to just under nine hours in 10 min increments
• LEDs let you know how much time is left
• Simple and fun to make with 41 parts
• Requires three AA batteries (not included Order Code L43AL)What can I do with this kit?
Set a timer for anything – boiling an egg, timing an exercise routine, or knowing how long to cool your 3D models – with this time elapse alarm. Use the two switches to set the hours and minutes from 10 min to 8 hours 50 min, then use the third switch to start it running. Red and yellow LED indicators show you exactly what time is set, and when the time runs down there is an audible buzzer alarm. This kit is an easy to solder with 41 parts and is great for beginners.
How does this kit work?
Practise your soldering and see how different components fit into a circuit with this kit. Learn how to solder LEDs, resistors, capacitors and switches. The 1N4006 microchip controls the output marking time and keeping the LEDs lit to give you an accurate time indicator. This kit requires a soldering iron and solder and may require wire cutters.
How easy is this kit to solder?
This is both a great way to get into electronics and a fun practical project. The kit requires three AA batteries (not included, Order Code L43AL) and comes with a battery box that screws onto the back of the board. You could add an enclosure or display around the board – just take care not to block the LEDs, buzzer or inputs.
