Home Made Circuits and Schematics

flop-flop’s output Toggles. 100Ω) 4. 220KΩ. output will be low. So you can select transformer rating 230V-6V or 230V-12V Working of Clap Switch Circuit Here the 555 IC operates in monostable multivibrator mode.1μF. Transistors (BC 548.e. Without the With the help of this circuit, speed of the fan can also be controlled by connecting regulator with individual outputs. Along with some of the other components, this circuit is mainly based on the two ICs i.e. NE555 timer along with CD4017. IC 555 timer in This is the circuit diagram of a small touch plate controller using IC NE 555 .This circuit is ideally useful for making touch operated doorbells, buzzers,toys etc which when touched on the touch plate operates the relay for a preset time and the turns off In one of my earlier post we learned a simple clap switch an IC for implementing the desired flip flop actions. The present design uses a different principle and utilizes only transistors for the above triggering actions. Looking at the circuit diagram This clap activated switch circuit can be used for any means of activation not just to turn on the lights. Let’s look into the working of this cool circuit. WORKING OF CLAP ACTIVATED LIGHT CIRCUIT A simple JK flip IC 74109 was used as an activator This circuit employs some very simple and cheap circuitry, and a simple program. It is relatively easy to make a hardware only clap on/off circuit, but I wanted to create a circuit that required two claps to switch using a handy-dandy LM324 quad op-amp IC. .

Clap Switch as 555 Timer, Transistors LED Resistors, Capacitors. Read this post to get knowledge about circuit diagram and working of PWM LED Dimmer Using Here, we use PWM to dim the intensity of light of the LED. LED Chaser Circuit using IC 555 Clap On Clap off switch circuits and connections. Initially the transistor is in OFF state because there is not enough (0.7v) base-emitter voltage to turn it ON. And the point A is at high potential, and point A is connected to Trigger pin 2 of 555 IC Here is a great collection of touch switch circuits. A touch switch is an electronic device On Off Touch Switch This is a easy to build on/off touch switch circuit with the well known IC 555. The modern mechanic switches are improved concerning of and Clap Off! [Rutuvij] and [Ayush] bought a clap switch kit That’s the complete circuit of a clapper using five transistors, something that just can’t be done with other builds centered around a 555 timer chip. .
