Introduction Hey everyone in this session we learn how to use KA/SG3525 IC to make PWM controller circuit having feedback, low voltage and over heating protection. Components So lets take look at components we need to make this circuit - 1.SG/KA3525 IC 2.LM358 IC 3.LM555 IC 4.10K NTC 5.Variable resistor - 10K*4, 500K*1 6.16-pin, 8-pin IC Base 7.Capacitors - 1nF*2, 100nF*4, 2.2uF*1) 8.Resistors - 100R*1, 220R*2, 1K*10, 5.6K*1, 10K*6, 15K*2, 100K*1 9.BC547*1 10.LED*2 11.Push Button*1 12.Zero PCB Working                                                                                                                            In this circuit we used SG3525 to make PWM controller and use...

Introduction In this session we will discuss about IR(infrared) controlled fan speed controller, in this circuit it consists of 74HC164 shift register IC and relay with some non-polar capacitor. Components Used  1)74HC164 IC 2)PC817 optocoupler 3)5v four-relay 4)Non-polar Capacitor 3.3uF, 2.2uF, 1.5uF, 100nF 5)VS1838 IR receiver 6)2.2uF electrolytic capacitor 7)Leds 8)100E, 1K, 10K, 1M, 2.2E(1W) 9)5v DC 74HC164 In this IC there is 8-output of which we use only 4 to controller 4-relays Pinout -      IR Receiver Circuit - In this circuit it uses IR receiver VS1838 to sense ir signals and 74HC164 IC used to get serial output from Q0 to Q3. Components                                 IR receiver with 74HC164 shift register IC Regulator - In the regulator portion I used capacitor based regulator its main advantage is it does not makes any hum-sound or any distortive noise along triac based...
