This circuit can be used variety of purposes like for counting persons through the entry gate, counting a large quantity of any. Frequency Counter - This is a circuit that uses IC NE555, five decade counters along with a 7-segment driver IC to form a 5 digit decimal counter. The counter output status can be checked with the examine instructions for use in other rungs in the program. K79 Kit 79 Three Circuits-In-One LDR Circuits We provide 3 complete and separate Light/Dark LDR circuits each with a relay on-board all in the one kit. Main board has the 3-digit counter circuit while the second board has Count and Reset pushbutton switches and debounce circuit. Continuous Up/Down Counter. 3 of IC2 will be pin input for logic “0” and logic “1” that from pin emitter of IC3(H21A1) into Ordered the the micro controller is up or down one number.
