[attachment=9965]COUNTER MODULEAn electronic Counter Module with 5-digit LCD display. The display increases by 1 every time a positive-going edge is applied to pin 3. A reset is available, and a tone output which can drive a piezo sounder directly and bleeps on every count and on reset. Square wave outputs at 512Hz and 32768Hz are also provided.COUNTER MODULE Specification:Current: 2µA standby 8µA average when countingCount range: 00000 to 99999 (resets to 00000 after count 99999)Max. input frequency: 7HzInput voltage range: 1V to 15VMin. duration pulse: <100µsOverall size: 68 x 35 x 24mm
I'm new to engineering so can anyone enlighten me please with what type of bcd counter and what type of 7 seg decoder i should choose? the voltage is around 5.1V after being regulated by zener diode. anyway the circuit I'm building is to count tennis balls. which ir emitter and ir detector are needed. once the tennis ball passes through, it cuts the infrare beam from ir emitter and so the active level switches from low to high (or vice versa) and thus triggering the counter to start counting and pass the digit to 7 seg decoder and lastly the 7 seg display lights up. if possible, can anyone tell me how to built the circuit and what type of components should i use? thank you lots lots lots!
