Innovation IC

Introduction : In this  session I make 'Solar Tracker' that tracks sun very well as I think the process works like a clock in my project some counter ,Op amp ,LDR ,Motor driver IC ,and Magnet sensor used. Working : So lets go on working of this project. In first phase a frequency generator(NE555 IC) generate frequency adjustable by preset then the PWM signal goes to binary counter CD4017 then to first optocoupler PC817 then it gives signal to motor driver ic L293D then after adjustable the PWM signal motor runs every 1 Hour interval and moves roughly 5 degree. In second phase the first LDR sense that its evening then it gives signal to LM358 Op amp IC so the whole counter disconnected by first optocoupler then motor stops running. After some time when the condition is fully dark(Night) then second LDR sense that its time to switch on reverse process to go solar panel at its initial position(for next day) then the in the last phase Reed switch is used with solar panel when ...

                                           Introduction Hey there in this session we will discuss how the buck boost converter works, here I am using XL6009 module and upgrade to buck boost converter. Components Modified Inductor  XL6009 Boost Converter Module Upgrading XL6009 Module First we need toroid inductor from old SMPS filter, now make 25 turns of 0.7mm copper wire with two wires hence we got two coils of same turns as shown in figure.  Make Dual Coil inductor of 25 turns each After this we have to remove the old inductor from xl6009 module and then we got two PCB points at which we will connect our modified inductor. Remove the old Inductor from XL6009 module Now connect the wire of both coils of inductor as shown in figure, the first coil wires connect between +VCC input and other to SW i.e. switch pin of XL6009 IC. And other coil wire will connect between in...

                                   Introduction Hey there in this session we will discuss about home automation i.e. IOT so we are using ESP8266-12F or Nodemcu and in software portion we will use blynk IOT to control all things over internet from one point to any point in the world. Components ESP8266-12F/12E or Nodemcu board  USB to TTL converter(if you don't use nodemcu or any development board) Breadboard 100R*5 resistors LEDs Circuit So this is minimum circuit requires to work properly and while esp8266 is connect with wifi it consumes minimum of 150mA so make sure you have used 3.3v regulator to work properly, as I have used AMS1117 3.3v regulator which is enough to power the esp8266. To program esp8266 you need any USB to TTL converter like CH340 or FDTI and wire connections are as follows                           ...

Introduction Hey everyone in this session we will discuss about working of PWM based motor speed controller, LED brightness controller. Components Required 1)LM555 IC 2)IRFZ44N or any N-Channel Mosfet 3)1N4148*2 4)1N5819*1 5)10nF, 100uF*1, 470uF*1 6)200K VR 7)330R, 1K, 2.2K, 10K 8)LED*1 9)LM7812 Regulator IC 10)100uF Inductor Working For controlling motor speed or LED brightness we generally use linear regulator which is simple in making but they don't have better efficiency as compared to PWM based controller so for that reason I made PWM controller with the help of very famous IC LM555, which is used in astable multivibrator mode. For controlling output we need to control the on time and off time of the switching mosfet it means we need to adjust duty cycle from 0% to 100% so that we can get desired voltage at the output. Here we see a inductor which is used to smooth the output. Testing  For the load testing we use 12v motor and 4v high power led. Circuit

Introduction Hey everyone in this topic we will discuss about inverter and working circuit with load test and efficiency. Components So lets take look at components we need to make this circuit - 1. SG/KA3525 IC 2. IRFZ44N N-Channel Mosfet 3. ATX PSU ferrite core transformer 4. 4700uF capacitor 5. Variable resistor - 10K*4, 500K*1 6. 16-pin IC Base 7. Capacitors - 1nF*2, 100nF*4) 8. Resistors - 100R*1, 1K*10, 5.6K*1, 10K*6, 100K*1 9. LED*1 Working First we have to look on the main part which is controller circuit based on KA3525 IC having feedback to control output voltage or auto voltage correction which is done by PC817 optocoupler for isolation from high voltage to low voltage side. The main component, transformer which is taken from old computer power supply and for winding of primary and secondary there's no complicated calculation is required because for step up transformer like inverter make total of 8T with 0.6mm wire of 5 layers in secondary with (4T + 4T) centered tap, an...
