I have used several circuits found on this forum and other websites, but nothing seems to work for me. I am looking to build a circuit that will transmit and receiver an IR signal. I am new to wireless communication and especially IR. I bought an IR LED from allelectronics.com, CAT# ILED-8 and some receivers, CAT# PCM-1, CAT# IRD-11.
The receiver that I have operates at 30kHz. I need a range of 6ft. I currently have a range of 3ft, but it is very sensitive. If I get slightly of the direct line of site I am screwed.
I am using a 555 timer circuit. I put 3 IR led's in series to give more range, which seemed to help a little, but not much.
I tried using RF, but bought the wrong modules and had problems with shielding.
The purpose of this part of the project is to create a robot follower. I have a robot ready to receive signal from 3 sides, left straight and right. Depending on which receiver receives the IR signal (from about 6ft away) the Hbridge will then drive the motors to turn the robot in that direction.
I have tried so many things an am currently frustrated with this part of the design. Please help.
Much Appreciation.
