TCN77 Based Thermometer Device

The project produces a thermometer based on a serially accessible digital temperature sensor TCN77 with a Serial Peripheral Interface (SPI).

AVR Based Capacitance Meter

The objective of the CapMeter project is to simply measure the capacitance between conductors such as PCB traces, wires, or legs of a capacitor with the functionality of an AVR.

Thermometer Device Using LM35

The project aims to produce a thermometer based on a precision centigrade temperature sensor LM35 of National Semiconductors which has an analog output voltage.

DS1621 Based Thermometer with LCD Display

The project uses the Dallas DS1621 Digital Thermometer and Thermostat chip board to connect directly to Port D of the AVR 2313 board.

Laser Range Finder via Webcam

The project comprises of a webcam, cheap laser pointer, and C++ coding to provide mono-machine vision with range information.
