Diy Projects With LM358


Hey Viewers in this blog we learn to make interesting projects with LM358 OP-AMP. Here I made two circuits Dark sensor and Obstacle sensor using LDR, IR led and Photodiode.


1).Dark/Night Sensor

Dark sensor consist of LDR and lm358 and a 20K trimpot we can easily adjust the sensitivity of the LDR using the variable resistor.

Components Required :

1.LM358
2.LDR
3.100E, 10K
4.20K Potentiometer
5.LED
circuit diagram :

2). Obstacle/IR Sensor

This sensor is used in many projects like line follower robot, automatic dispenser, Distance meserment and many more. In this circuit we have used a IR Led and Photodiode, 20K pot we can adjust the sensitivity of Photodiode.

Components Required :

1.LM358
2.IR led & Photodiode
3.100E*2, 10K*1
4.20K Potentiometer
5.LED

XL6009 Buck Boost Converter

                                           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...

How to use Hall Effect Sensor

How To Use Hall Effect Sensor Introduction : We will talk about hall sensors and their uses here I am using A3144 sensor this sensor has 3 pins VCC, GND, and OUTPUT it works on 5v dc its output is open collector so we get negative output when passes near magnet and this is digital sensor so you can use it directly with your projects it means no need of any comparator.  And this sensor is used in BLDC motor, Fridge door automatic light, magnet pole detection etc. Watch Practical experiment Video of this Sensor . Pinout of A3144 : Circuit diagram : Buy Electronics components at very cheap price :  Quartz Components 1) A3144 Hall Sensor 2) Leds 3) Resistors 4) 5v SMPS   5) Breadboard   6) Breadboard Jumper Wires 7) Crocodileclips
