Introduction on Product Counter Project:
The main objective of this project is to develop a circuit which enhances the counting process. Industries will be manufacturing many products and they cannot be counted easily. This circuit was developed such that it can be used for counting products going over a belt, and for counting persons passed at a point etc. This can display from three to ten digit numbers and can count unto thousands.
Brief into Design and working :
This system makes use of IC’S , LED, resistors, Variable resistors, LCD, Seven segment display and power supply.LM311 IC is a voltage regulator used for comparing the voltages and generates the output. 4033 IC is a counter and an output decoder. Variable resistors are used for controlling the electrical devices in terms of power.
Resistors are used for controlling the flow of electric current and providing desired amount of voltage in electric or electric circuit. LED is a semiconductor light source which are used as indicator lamps in many devices, and are increasingly used for lighting. light dependent resistor is a resistor whose resistance decreases with increasing incident light intensity.
Seven segment display is used for visual numeric display. The output from opamp is given as the clock for seven segment counter 4033.the 4033 counter counts and displays in seven segment display.
