The zero pin loader is a bootloader for the PICmicro 18F series in order to avoid the use of I/O pins by exploiting the /MCLR pin as the solitary interface between the PICmicro and the host PC.
The project uses the Atmel ATmega8 microcontroller to create the standalone processing engine AVRcam that is capable of visually tracking 8 objects of 8 different user-defined colors at 27 frames per second.
The wheelchair detection system has been designed to distinguish the size of a wheelchair or handcart by using an in-ground capacitive sensor to let a door open automatically.
