"Our project was for measuring various properties of water flowing through a system. We interfaced sensors that measured pH, electroconductivity, and flow speed to our Dragon-12 board using SCI. We also have a relay that injects fluid into the water speed."
"For this project I intend to show how an ADC (National Semi ADC0808CCN) can be interfaced with the Dragon-12 board [...] to measure and report voltages from each of the 8 inputs of the ADC."
Roman used the IR receiver to control the 7 segment display and RGB LEDs on the Dragon-12 by pressing buttons on a remote control.
"The wind meter creates a pulse, at frequencies relative to air flow speed, while the microcontroller measures the frequency of the pulse, manipulates the data, and displays it in frequency (Hz) and speed (f/m) on the Dragon board LCD."
Loren interfaced a SenseAir CO2 sensor to the Dragon-12 board and displayed the CO2 level on the LCD display. The level controls the speed of a ventilation fan.
Cody used XBee modules to implement a remote temperature and humidity sensor with readout on the Dragon-12 board.
Gary was my first student to use the CAN bus interface on the 68HCS12 microcontroller. His project was to interface with a "Multiplexed Vehicle Electrical Center."
"[...]design and development of a digitally controlled linear power supply. The microcontroller used was an ATMega8 which was chosed due to the low price and availability of a $12 development board."
"The purpose of the project is to create an electonic lock with a re-programmable lock code that shows the new code as it is being typed in, or the current state of the lock."
"My idea for the term end project is to use an ultrasonic module HC-SR04 and the Dragon-12 microcontroller board as a home garage proximity sensor for parking a vehicle at the appropriate distance from the wall."
"The scale consists of a Dragon12 development board, a load cell platform, and an amplifier/ADC circuit. [...] A user interface is provided to allow functions such as unit selection and calibration, and a standard RS232 protocol has been implemented to allow interface with PC software."
"A line-following robot is an automated robot that detects and follows a black line on a white surface. It is driven by two wheeled powered motors, and the control system is programmed to detect the black line with IR sensors."
"[The] ultrasonic sensor will scan for nearby objects and it will turn on the LED when the sensor detects an object within one foot range. It also shows the distance on the 7-segment LEDs whenever the object moves."
An incoming analog waveform is modified (voltage limiting) based on user interface input. The waveform is then output, amplified, and sent to a speaker.
"For my project, I decided that I wanted to be able to use the Dragon 12 board to display a visual number readout of what the actual transconductance is from my vacuum tube tester."
