A four digit UP counter module designed using CD4026 ICs which can be used to count from 0 to 9999. Count will increment in each LOW to HIGH pulses applied at the CLK input of counter module. Module can be used to count motion easily by connecting a PIR motion sensor directly to the module. No programming required.
This module will help you to make LED flashers of different speeds by varying the value of R1, R2 and C1. Leave POT1 and R2 unconnected. POT1 is parallel to R1 and POT2 is parallel to R2. Only one from each set need to be connected. R1 is 10K. This module can be used for generating clock pulses for Johnson counters, ring counters. digital clocks etc.

Here, we are using 7805 as the voltage regulator. 7805 will give stabilized 5V output. Replacing 7805 by 7808, we can get stabilized 8V output.
