Here is a simple 4026 manual digital counter circuit with reset and pause this counter circuit applicable for order to count certain events such as people counter product counter etc circuit uses digital counter ic 4026 and 7 segment display. 0 60 counter with start stop and reset functions reply to thread discussion in homework help started by kirinoarashi nov 6 i have done a circuit which is able to count from 0 59 and can recycle the reset button is also working fine however upon adding the start stop button it counts from 00 59 and can pause and resume properly . Advanced led temperature indicator use of a v f converter in monitoring temperature in degrees fahrenheit 0 f electronics counter circuit digital counter counter using ttl ics counts up to 10000 twilight lamp blinker indicate obstruction by blinking in adjusted time. Circuit diagram and explanation the circuit diagram of object counter is quite similar to my previous project digital stopwatch circuit but a little complex in this circuit we have used a comparator ic lm358 and ir transmitter and receiver pair for detecting a object. For a 0 5 counter we use 0110 6 as the reset trigger so again qa is interfaced with input b to get our 4 bit asynchronous counter now qb qc are interfaced with r01 r02 respectively we have our 0 5 counter these circuits are pretty straight forward if you just refer the pin diagram
