This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011. For the 4017 IC is a 16-pin CMOS decade counter. It takes clock pulses from the clock input, and makes one of the ten outputs come on in sequence each time a clock [...]

This circuit use test waves light receiver signal pulse change LED1. For R1 and C1 be formed control the rate pulse of the circuit. Besides equipment all value in the circuit will give the rate pulse about 600Hz. Other detail see add [...]

A pair of LEDs having different wavelengths can supply the stimulus for a rudimentary spectral analysis during quality-control sorting operations. By measuring the reflectance of each LED, the circuit in Fig 1 can provide information about the spectral response of the object under test. The circuit’s operation is akin to the human eye’s using three [...]
