The BASIC Stamp is comprised of several components: PIC16C57-20/SS - a Microchip 2K 8-bit microcontroller programmed with the the BASIC Stamp "Interpreter" that runs the Parallax BASIC Stamp code like a mini operating system; the 24LC16B EEPROM - a Microchip 2K EEPROM (electrically erasable ...
©1998 Microchip Technology Inc. DS00645B-page 5 AN645 Learn A LEARN input in any state will put the system in learn mode. After learn is completed or timed out the system returns to the previous state.
The entrance and exit security gates are connected to the servomotors, which are controlled by the PIC16C57 microcontroller. These microcontroller servos are programmed to receive high and low signals that allow for the movement of the servomotors.
