Introduction

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 monostable circuit which is one of the most common uses for this chip.

Included in this kit

• 8 Dip Socket
• NE555
• 10uF
• 100nF Capacitor
• 1kΩ Resistor (x 2)
• LED (Red)
• Switch (Tactile)
• Potentiometer
• PP3 Connector
• PCB (555 Monostable)

What makes this special?

MitchElectronics kits are designed with education in mind and as such use high quality double sided PCBs. The through-hole plating of each pad means that even the most novice of builders will not be able to tear traces or break pads (unlike many other professional kits which only use single sided boards to save costs). These kits are also RoHS compliant which make them safe to use and no kits use non-RoHS components such as LDRs (which contain Cadmium).
