Build a simple timer circuit with buzzer output Learn about 555 timer circuits A great way to practice your soldering skills Designed and manufactured in the UK by KitronikThis Kitronik Timer kit uses a dual 555 timer, which once started by pressing the button illuminates an LED until the desired time out period has elapsed when a buzzer is sounded. The duration of both the delay and buzzer sound period can be determined by the student and are easily adjusted by PCB mounted potentiometers. This allows the board to be used for a variety of applications, such as an egg timer or a timer for a game (Max time period 200 seconds, max buzzer period 10 seconds).Kit contents:1 x PP3 clip lead1 x 4AA battery holder1 x Slide switch1 x Push to make switch1 x 556 (dual 555) timer IC1 x 14 pin IC holder1 x Piezo buzzer3 x 10nF capacitor, ceramic2 x 100uF capacitor, electrolytic1 x 330ohm resistor2 x 10Kohm resistors1 x 1Mohm resistor1 x 100Kohm potentiometer1 x 1Mohm potentiometer1 x 5mm red LED0.5m connecting wire1 x Timer PCBPCB dimensions: 54mm x 46mm.Requires:4 x AA Batteries.Soldering Iron.Solder.Wire Cutters.This kit is supplied in blister packaging.
