Build a 555 astable timer circuit Learn about 555 timer circuits A great way to practice your soldering skills Designed and manufactured in the UK by KitronikThis 555 Timer kit from Kitronik is perfect for studying the use of a 555 timer in its astable mode, where it produces a square wave output. The frequency of which is adjustable via the variable resistor. The board has a choice of two outputs. The logic output can be used to drive another IC or a speaker can be connected so the tone is heard (e.g. a door bell). The push button switch connects to the reset line such that the IC is only active when the button is pressed.Kit contains:1 x 555 Timer IC1 x 8 Pin IC holder1 x 3.3KOhm Resistor1 x 10KOhm Resistor1 x 47KOhm Potentiometer2 x 10nF Ceramic capacitors1 x BC547 NPN transistor1 x Push to make switch1 x PP3 clip lead1 x 3AA battery holder0.5m Connecting wire1 x Tone generator PCBPCB dimensions: 40mm x 40mm.Requires:3 x AA Batteries.Soldering Iron.Solder.Wire Cutters.Wire Strippers.(Also depending upon desired use a speaker may be required).This kit is supplied in blister packaging.
