Random Number Generator by IC 4017 and 4011

This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011 integrated circuit. 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 pulse arrives. Usability press S1 forLED Flasherrespectively. By pressure (Close) S1 make LED all stick dim (Dimly). When liberate (open) S1 make LED stick bright at LED any one to one’s fate. Besides value expansion C1 be 4.7uF make LED flasher slow down. The detail is other invite friends see in the circuit leisurely.

Standard Touch Switch by Gate of IC 4011

This circuit uses a 4011 logic gate digital as the bases of the touch switch.
It are Standard and very easy because I used a Gate of IC 4011.
In circuit at pin 2 of 1/4 IC is Hi logic “HI” alway.
If touching the plate connected to the 2 numbered,so logic output is Hi ,but don’t touching
is Low logic.
The 22M resistor on pin 1 causes the the circuit to be very sensitive to the touch.

Water Level Alarm by 4011

A circuit that offers visual indication of fluid level in a vessel, with a switchable audible alarm. Example uses would be to monitor the level of water in a bath or cold storage tank.
This circuit will trigger with any fluid with a resistance under 900K between the maximum separation distance of the probes. Let me explain further. The circuit uses a 4050B CMOS hex buffer working on a 5 volt supply. All gates are biased off by the 10M resistors connected between ground and buffer input. The “common” probe the topmost probe above probe 1 in the diagram above is connected to the positive 5 volt supply. If probe 1 is spaced 1 cm away from the common probe and tap water at 25 Â° C is detected between the probes (a resistance of 20k) then the top gate is activated and the LED 1 will light. Similarly if probe 2 at 2 cm distance from the common probe detects water, LED 2 will light and so on. Switch 1 is used to select which output from the hex buffer will trigger the audible oscillator made from the gates of a CMOS 4011B IC.
