i am new in using pic16f877A to program a electronic project. can I use pic16f877A to connect with 10 IR sensor and display an output at LED display? Pls give some advice if anyone know.

Probably?, but your question is far too vague for any accurate answer - you might check my tutorials for some PIC examples though?.

Sorry about my vague description about my project. Actually, I want to build a prototype of car park space tracking system with connect 10 different GP2D120 SHARP IR sensors with PIC16F877A as input and display output in the dot matrix LED display. Do PIC16F877A suitable for this kind of IR sensors and how I write a program for control them.

the 877a has built in adc , so that u can get digital equivalent of the reflected IR , closer the object , higher the value . personaly for the above appln, i would prefer ultrasound than IR since the reflectivity differes with surface

Hi, akg
Thank for your advice. I already surfing internet for short distance ultrasonic sensor for my project. However, I meet problem to deal with sensing distance of ultrasonic sensor since I am building a prototype for multistorey car park. can u suggest me some short sensing distance ultrasonic sensor.

is anyone have the schematic diagram for car park space tracking system?
