Light Dependent Resistor Unit (LDR)

Complete with Regulated power supply of + 5V/500 mA. Provided with 4 Logic input switches (bounceless) 4 LED Indicators (Buffered) Functional diagram of :- 1. 3 Input NAND – 6 No. 2. 4 Input NAND – 4 No. 3. 1 Input NOT Gates – 4 No. is printed on board. 4. 12 Interconnection Leads and User’s Manual is provided.

A common anode seven segment module is fitted on a board with 8 bit dip switch to control the each segment of seven segment LED display. The inputs A-D of a display driver are connected to the binary coded decimal (BCD) outputs from a decade counter. A network of logic gates inside the display driver makes its outputs a-g become high or low as appropriate to light the required segments a-g of a seven segment display. A resistor is required in series with each segment to protect the LEDs

To study the AND digital logic gate and verification of the truth table.
