The Conveyor Belt Object Counter using LDR and 7-Segment Display with the 8051 microcontroller is designed to count objects passing in front of an LDR (Light Dependent Resistor) sensor. The system works by detecting light interruptions when an object crosses the sensor, causing a change in the LDR’s resistance. The microcontroller processes this change and increments an object count. The count is then displayed on a 7-segment display.
