Here is a sample experiment!

Digital Up/Down Counter Experiment  
Now you are going to build a Digital Up or Down Counter with a Seven-Segment display. You will use the 555 Timer chip wired as an Astable Multivibrator circuit to input pulses to cause the counter to count.
Then you will use the 4029B chip as a Decade Up or Down Counter to count in binary, from 0000 to 1001 or from 1001 to 0000. These binary numbers, from the 4029B chip, will be sent to the 4511B Seven-Segment decoder chip. The 4511B will be connected to a common-cathode Seven-Segment display which will readout the decimal equivalents of the binary numbers. 

Wiring of the 4029B
Note that pin 10 of the 4029B is connected to ground to make it work as an Up/Down counter. You already know that when pin 9 is connected to ground the 4029B works as a Decade Counter. 

Circuit Description
This circuit consists of a common-cathode Seven-Segment LED with pin 8, the common- cathode, connected to ground. Note:Pin 8 and pin 3 are connected internally, therefore we do not connect anything to pin 3.
This Seven-Segment Display is connected to an Integrated Circuit CMOS 4511B which is connected to the outputs of a 4029B counter chip. The 4029B chip is driven by a 555 Timer chip which emits clock pulses.
Each time a binary number is present on the inputs of the 4511B, a decimal equivalent number will light up on the Seven-Segment display. 


  • 1. Build the circuit shown, following the schematic or pictorial diagram.
  • 2. Connect power and observe the Seven-Segment LED display count down from 9 to 0, over and over again.
  • 3. Now, disconnect pin 10 of the 4029 from ground and connect it to positive. It should now count up from 0 to 9, over and over.

In this experiment you saw how the Astable Multivibrator, Binary Counter and Seven-Segment Decoder work together to make a Digital Up/Down Decade Counter with Display.
