Temperature Controller (1)

Open Source AVR Temperature Controller using ATmega48 microcontroller

The open source project allows you to control DC appliances based on the temperature of two thermistor inputs. It uses AVR ATmega48 as main processor. The controller has both green and white LEDs to indicate status. The project output is connected to N-Channel MOSFET, AOD444, for switching with current up to 4A. For higher current you can use relay. …

Touchpad Handwriting Recognition

AVR Touchpad Handwriting Recognition using ATmega644 microcontroller

This ATmega644-based project implements a touchpad input system which takes user handwriting input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but it could be easily generalized to include any figure of completely arbitrary shape, including alphanumeric, punctuation, and other symbols using available training system. A …
