Steps
1. Gather parts
Gather your parts. Note that the capacitors in the picture are actually a 10pF capacitor and a 100uF capacitor. It's recommended that you use 10nF and 0.1uF capacitors as shown in the schematic.
2. Insert 555 timer
Insert the 555 timer in your breadboard. There is a small circular dent on the top of the chip that indicates pin 1. Make sure you put pin 1 on the top left side as shown.
3. Connect 555 timer to +5V
Connect pins 4 and 8 of the IC to the +5V rail on the right side of the breadboard.
4. Connect 555 timer to GND
Connect pin 1 of the IC to the GND rail on the left side of the breadboard.
5. AC couple pin 5 of the timer to ground
Place the 10nF capacitor between pin 5 of the IC and the ground rail. The value of this capacitor is not very important, and the circuit will probably still work without it.
