This is a project that is a short range, infrared and ultrasonic scanner that uses a standard hobby servo to move the sensors and a color LCD screen to display the information from the distance sensors. The information displayed on the LCD is an overhead view of the scanning area, with increments of distance from the distance sensors. This is the figure of the project;
The core of the project is the ATMEGA32 microcontroller from Atmel. It controls the servo, gathers information from the sensors and places the information on the LCD screen. There is 32K of flash in the microcontroller and the software uses about 13K of that. Since the LCD uses a maximum of 3.3V, the microcontroller is run at 3.3V.
