In this project I have explained the basic specifications of a servo motor and also how to control a Servo Motor using a 555 timer IC, and just two push buttons. WHY SERVO? Servo Motors are used in variety of fields. These are mainly used as actuators in those areas where we need a precise […]

How to Add a Dimmer Facility to a LED Bulb
In this article I have explained how to make an LED dimmer circuit for enabling a dimming facility to any mains operated LEDs bulb. Update: [Using Capacitors, it Works] If you think PWM dimming control might not work for commercial LED bulbs, then the best method is to use series capacitors, which might just do […]
32V, 3 Amp LED Driver SMPS Circuit
In this article I have explained a 32V, 3 amp SMPS circuit which may be specifically used as an SMPS 100 watt LED driver, rated with the same specs. The circuit of the proposed 32 V, 3 amp smps led driver may be understood with the the help of the following points: Circuit Operation The […]
IC 4047 Astable, Monostable Oscillator Circuits
In an IC 4047 astable oscillator circuit, the output of the IC continuously generates a switching ON/OFF signal. Since the output is never in a stable state and constantly switches between and low and high, it is called an astable multivibrator. The astable ON/OFF switching frequency is adjustable and can be varied by changing the […]
How to Design Customized 220V SMPS Circuits
We many times think that how we can make a SMPS circuit, and we feel that this is very complex. But that is not so because we can do this by following simple manual calculations step by step. We only need to know that SMPS design is always starting from the transformer. We cannot make […]
IC IR2111 H-Bridge Inverter Circuit with Shut Down
This circuit is basically a H bridge inverter where two IC IR2111 are working for driving four MOSFETs that are connected in H bridge way. We also see that there is a overload and over current shut down using BC547 small transistors. So what happens is that we can run a load with AC waveform […]
