Summative Circuit 555-Timer Traffic Light

This is a red blinking light circuit, designed to work somewhat like a traffic light circuit.

Supplies

Tools Needed:

Wires
2 555 Timers
LED
Resistors(330 ohms , 560 ohms x 2, 100k ohms, and 47k ohms)
2 100 microfarads capacitors
Battery & Battery Cap
Breadboard

Step 1: Starting to Build the Circuit

Place 555 Timer IC On Breadboard

Step 2: Adding to 555 Timer

Place wire from Pin 1 of the 555 Timer to negative rail.

Then, place wire from Pin 8 to positive rail.

After, place wire from Pin 4 to Pin 8.

Then, place wire from Pin 2 to Pin 6.

After, place 100k ohms resistor from Pin 3 to Pin 6.

Finally, place a capacitor from Pin 2 to the negative rail.

Step 3: Second 555 Timer

Place another 555 Timer IC

Connect Pin 3 from the first timer to Pin 8 of the second timer.

Pin 1 of second 555 timer goes to negative rail via the wire.

Pin 2 to Pin 6

Place 47k ohms resistor from Pin 3 to Pin 6.

Pin 4 to positive rail via wire.

Finally, place the second capacitor to negative rail via the Pin 2 of the 555 timer.

Step 4: LED & Resistor Placing

Place the LED

Connect the wire from the anode of the LED to the positive rail.

Pin 3 of first timer to the 560 ohms resistor.

Place the resistor to the c41 hole.

Step 5: Attaching Battery to Power Circuit

Attach Battery cap to Battery, then put the positive wire from the battery cap to the positive rail, and the negative wire to the negative rail. Now, the LED should be blinking on and off every 5-7 seconds.
