Step 1: Components
1. 555 Timer IC
2. 1000uF Capacitor
3. 10k Resistors x 2
4. 47k Resistor
5. Tactile Switch
Step 2: Circuit Diagram
Presented here is the circuit diagram of the 555 timer project.
Step 3: Connections-1
First of all mount 555 timer IC on Breadboard.
Now, connect pin no. 4 and 8 of the IC.
Connect pin no. 6 and 7 of the IC.
Step 4: Connections-2
Now, connect a 1000uF Capacitor across pin no. 2 and 6 of the IC.
Then, connect an LED across pin no. 3 and 4 of the IC. Positive Terminal at pin no. 4.
Connect a 10k Resistor across pin no. 2 and 4.
Step 5: Connections-3
Connect a series of 10k Resistor and 47k Resistor across pin no. 7 and 4.
Now, place a tactile switch across pin no. 1 and 2. Use it as a trigger.
