IR Proximity Sensor / Obstacle Detector circuit on Breadboard | LM358 Op-Amp projects

A tutorial on How to make an InfraRed (IR) proximity sensor circuit along with detailed explanation on how the circuit works. The sensitivity or Range of detection can be controlled by adjusting the potentiometer. This circuit can also function as an InfraRed receiver and Object detector. For circuit diagram plus more Info, visit: https://elonics.org/infrared-ir-proximity-obs… Components Required: * LM 358 IC * 1 InfraRed LED PhotoDiode pair * Resistors: 2 x 270R, 10K * Potentiometer: 10K * Breadboard * Power Supply: (3-12)V * Few Breadboard connectors Note: For supply voltage of 9V or more, use 1K resistor for LED and 470R for InfraRed(IR) LED.
