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.
