| LED Volume Level by Jonathan
Dahlin.
Measures the volume level of an audio source (here an iPod) and
indicates the level on a row of LEDs.

| Bed Buddy by Ryan Fitch.
The Bed Buddy is a digital clock with a motion detected night light, a temperature
controlled fan, and an alarm buzzer. The project uses two Dragon-12
boards, the second is inside the fan box.

| I/V Curve Tracer by Gamachu
Woticha.
The microcontroller steps the base current and collector voltage of
a BJT under test and measures the collector current allowing the
plotting of characteristic IC versus VCE curves at different IB
values.

| Automatic Skittle Sorter by
Daniel Dubach.
A homemade mechanism takes Skittles one at a time, determines their
color via an optical sensor, then drops the Skittle in the correct
tube for the color. Daniel is showing that it works even with his
eyes closed. (OK, I just slipped up as the photographer here!)

| Implementation of a Motion Light by Trevor Albertus.
A motion detector is interfaced to the Dragon-12 and lights up a
lamp when motion is detected. A second light is turned on and off
via a pushbutton.
|
| DC Motor Interface by Farhad
Sabet.
Push buttons turn on and off and select the direction of a DC
motor. The motor circuit is opto-isolated from the microcontroller.

| Servo Operated Airsoft Mount
by Michael Saltzman.
A two axis servo mount is controlled from the Dragon-12 using an
Atari 2600 joystick. Michael aims it right at the camera!
|
| Time Lapse Camera Controller
by Alan Canida.
Alan also had to build a solenoid activator for his camera's
shutter. The push buttons set the interval, which is displayed on
the LCD display (which unfortunately cannot be read in the photo).
|
| RFID Access Control by Gene
Frye.
The microcontroller receives RFID tag numbers from the receiver and
displays them on the LCD. In this photo, the LCD display can be
seen.
|
| Garage Parking Assistant by
Michael Zaiser.
A sensor measures the distance between the car and the end of the
parking spot and signals via red/yellow/green lights and sounds how
close the car is.

| Laser Tag Team Project by (from
left to right) Emanuel Azgur, Alan Muench, and James Eastham.
This is the first time I've had a team project in the class, so the
project had to be appropriately ambitious. The used "gutted" laser
tag guns interfaced to Dragon-12s in the boxes. The
microcontrollers were coded in C language. Multiple state machines
were implemented in code to handle firing, reloading, and hits. The DAC on the Dragon12
connects to an audio amplifer for sound effects which they stored
as wave files or encoded as timer channel tone patterns. This
represents not only the first project in C but also the first to be
stored in the flash memory instead of the EEPROM.

| Velocity Controlled VCA by
Douglas McCaig.
A motor's speed (considered proportional to ambient sound level) is
used to control a voltage controlled amplifier to adjust the sound
level of an audio system.

| Instrument Validator by
A. Raydt Vaz.
Raydt project uses the Dragon-12 to validate a
manufacturing process on his job. He provided the pictures shown
here.
