Electropepper documented his small SMD digital counter build:
This is a simple digital counter with a serial rs-232 and a 7 segment display, i started this project to count items on some shelfs, but it can be used for anything, it is also, for the exception of the connectors, completely on SMD components.
The circuit is made around a PIC16F88, and takes use of its internall EEPROM to store the number.
Check out the video after the break.
Via the contact form.
Ik really like the simplicity of this project. Simple but effective, could i.e. also used for counting the number of times a door is openened/closed, the number of people entered the shop/room etc.
hello ,, i want some help in my project of infrared counter using 8088 microprocessor , 27160 EPROM and latch 373 … i need coding of EPROM for infrared counter… can u plz help me
