Hi again pyro..
I can't see the 18f452 fuses configurations. And when I power up the circuit the LEDs are all shining. There is nothing happen.. What do you suggest me ?

Hello again Pyro..
I built the circuit an programmed chip..Everything is controlled but, when I aplly the power all the leds are ON and servomotor does nothing.Just LEDs are lit. Suggest me something to do. if not I'll be a personal radar!

Ok Pyro.. I'll do it. How am I calibrate the sensor ?

ISIS simulates the program and LEDs are not ok.LE signal is coming to all 373's pin 11 but nothing happen. RD0...RD7 is always low. RB0..RB4 logic states changing every 1 sec. (1sec high,1sec low), but nothing happen. Help me !!!

@solidus The circuit works just fine, but as the write-up says you will have to calibrate for your specific sensor and enviornment. IR is not the most stable method for proximity sense for all enviornments, this is why you see it in limited commercial applications that have many known variables, li...

is this radar really working ? I'm sorry but This site and this circuit look dead.

hi to all. I'm new on this forum. I read all. I want to make this project with 16f877. I changed the p18f452 to p16f877. I cant compile it. Can someone pls help me about the hex. files of 18f452 and 16f877 ?
