In this PR, we will put more concernson the working principle of infraredsensor and the output from it. PICmicrocontroller and programming arenot required.IR (Infra-Red) is the typical lightsource used as a sensor in hobbyrobot to sense opaque object. Thebasic principle of IR sensor is based

on an IR emitter and an IR receiver.IR emitter will emit infraredcontinuously when you provide powersource to it. Since there is no sourceof power for IR receiver, it would notemit any light. It will only receiveinfrared if there is any. Usually we willattach the IR emitter and IR receiverside by side, and point them to a

reflective surface.

When the IR receiver receivesinfrared, it will generate voltage at itspin. The generated voltage is in therange from 0V to 5V depends on theintensity of infrared it received. Thevoltage will drop to zero if there is noinfrared received. The problem arise

where our microcontroller onlyrecognize digital input which is 0Vand 5V. If the infrared reflected isless, the receiver would probablyproduce a 2V or 3V andmicrocontroller is unable to deal withthese analog values. Thus, we needa comparator (LM324) to solve thisproblem. By using this comparator,

the output voltage from IR receiverwill compare to an input voltagethrough a variable resistor. Thecomparator able to compare bothinput voltage and generate either 0Vor 5V where we can connect it to ourmicrocontroller.
