| Summary: | We use the digital and analog concept in our application. The components involved such as timer, decoder, demultiplexer, Light Emitter Diode (LED) and resistors. The time is use to generate the clock pulse, the counter act as a counting device. While demultiplexer or 1 to 16 decoder will trigger the LED to lit. Switching system is used to control the circuit. When the switch is closed, only LED remains on. Only one current limiting resistor is used for all LEDs, since only one is on at any time. All these component, are cascaded on project circuit board (PCB). Using +5v supply, this circuit is tasted. The trouble shooting is done in order to over come the problems. The objective of the circuit design is met when one of the LED is on the any time once switch is pressed |
