Temperature Controller Based on AVR

An AT90S2313 and a Dallas DS1621 Digital Thermometer to create a controller where the temperature is displayed on a dual 7-segment display while the parameters are set using the two buttons.

Temperature Controller for CPU Cooling Fan

The objective of the project is to build a temperature control that can be adjusted by the user and be able to control several fans with just one sensor.

Servo Motor Controller from Dedicated IC

The project utilizes the tiny 8-pin PIC12C671 to build a simple serial servo controller chips.

Parallel Port Used to Control Peripheral Electronics

Any peripheral component can be controlled by the 25-pin parallel port by assigning a high & low or ON & OFF state to each pin.

Controlling Servomotor Position from an Analog Sensor

A microcontroller is used to control servomotors since they are the easiest way to start making motion where the position comes from the value returned from an analog sensor.

Temperature Control for Computers

The project was designed for standalone computers to monitor and control the temperature and fan which can be run manually or autonomously.
