#121331 - using a 555 it would be simpler Responding to: ???'s previous message |
Dear Mahesh
Using a 555 based IR proximity detection would be better. but if you want to do it using a microcontroller then here is an example http://www.dprg.org/projects/1998-08a/index.html this is using a "small footprint" PIC it contains all the intelligence required for IR proximity detection. I wonder if there is a 8051 equivalent (I dont know of any) of a 8 pin PIC having internal oscillator and good current drive capability. hope this helps ! |

I do believe you've mis-stated the problem | 01/01/70 00:00 | |
