1 Capacitor Radial 10 uF 25v 20% 85c 4x5x1.5mm

1 DECADE COUNTER/DIVIDER DIP-16 (IC 4026)

1 Standard Timer Single 8-Pin Plastic Dip Rail (IC 555)

1 Resistor Carbon Film 1k Ohm 1/4 Watt 5% (In Bags of 10 and 100)

1 POTENTIOMETER,100K OHM,3362P-104LF,SINGLE TURN,.5 WATT,CERMET

What you will need:

Wire strippers and cutter

Needle nose pliers

Wire for connections

Step 2: Showing the Diagram

In this step, you are going to install the mini common cathode LED display, the IC 4026, and the IC 555 timer in your mini breadboard.

Step 4: Mini LED Display Pins

The mini LED display is a common cathode LED display 7-segment and its distribution of pins is showed in the picture attaches in this step whose numeration forms an inverse "U" from 1 to 10 pin of this component.

Step 5: Connecting the LED Display Pins

In this step, I am utilizing a color of wire only. For that, you need to observe carefully the diagram in step #2 to identify the LED display pins and their right connections.

Step 6: Connecting to +5V

In this step, you are going to connect to GND. Note that I am utilizing the following colors: orange, brown, and metallic. It's so that you are following the diagram of your project.

Step 8: Connecting the Capacitor

What is the point of this? The count isn't even in seconds.

braulio777 (author)Silent_Shadow2014-08-24

You can adjust it with the pot of 100K so that the counter counts faster or slower.
