The 555 timer is arguably the most famous integrated circuit ever invented. Created by Hans Camenzind in 1971 for Signetics (now NXP), the 555 timer is still widely used and in production. These devices are so common that over 1 billion are made each year. But what makes the 555 timer so useful? Why is this tiny little 8 pin device still be mass produced despite being over 40 years old? In this kit you will be making a 555 astable circuit which is one of the most common uses for this chip. This kit is available in either single packs, group packs, or class packs with larger packs having a bigger discount per kit.

The 555 Astable Kit is highly ideal for use in the classroom as it is a small kit that can be constructed in under an hour. It can be used as a teaching aid for learning how to construct electronic kits as well as an example of how the 555 astable oscillator works. The potentiometer provided with the kit has a nut which allows for mounting to a plinth for design and technology related courses while the LED can easily be mounted remotely from the PCB and wires used to connect the LED to its associated pads. The 555 Astable Kit is also ideal for use as a stand alone module for projects and applications including fake car alarm signals, signal indication, low-frequency gate control for audio, and as a clock source for digital logic circuits. If you require a one-shot signal then the 555 monostable is an ideal alternative to this product and the Voltage Controlled Oscillator Kit is more ideal for applications requiring higher frequency waveforms of varying type.
