Kitronik Buzzer Timer Solder Kit
• Build a timed buzzer kit
• Practise soldering and get familiar with components
• Easy to solder with 21 parts
• Requires four AA batteries (not included - Order Code L43AL)
• Designed and manufactured in the UK by KitronikWhat does this kit do?
Create a circuit that allows you to set off a buzzer after a certain period of time (manufactures code 1004). The time before the buzzer goes off and the time it sounds for are set by you using the variable resistors. You can set a time up to 200 seconds before the buzzer goes off for up to 10 seconds. 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. It’s also a great way to see how components work with each other. Get experience soldering resistors, potentiometers (variable resistors), capacitors, IC holders, LEDs and buzzers. This kit works by using a 556 timer chip (a dual 555 timer chip). You can change the time that the 556 is set for by altering the resistance of the corresponding variable resistor. There are two variable resistors that can be set individually for separate times. This kit requires soldering
and may require wire cutters, a screwdriver and wire strippers (not included). How easy is it to solder?
This is a great kit for beginners as it is easy to solder. It also serves as a brilliant 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 four AA batteries
