hi,
how to read the data coming from IR receiver side using PIC 18f4520 microcontroller?? please help me guys...Also guys i'm using HIRL5020 IR led at transmitter end and tsop 31238 at the receiver side... Am i using the right components?? Please reply ASAP
Define the range of signal you need to verify a person interrupted the path...= OFF1= Min, Max (valid)...what is this mean??
Should I first take the waveforms obtained from the IR sensor??so that i can know the range of the signal transmitted by the sensor....can you please be more precise...
hi,
i want to know how to detect edge detection using pic18f4520 by using C language? i want to use this for my project. So kindly reply back soon .... thank u :)
thank u for replying,
sorry but i'm new to the programming. i din't get to know, how to implement SunnySkyguy idea. can i get the syntax for his idea i'l try to do it. should i do the program based on edge detection of the signal? please help me.
