Make sure your kit has the following items: |
|||
<source src="solder.mp4" type="video/mp4"> |
|||
* Arduino Uno ([http://www.sparkfun.com/products/9950]) |
|||
Your browser does not support HTML5 video. |
|||
* USB A to B cable (B has a large, square end) |
|||
</video> |
|||
* 850mAh LiPo ([http://www.sparkfun.com/products/10718]) |
|||
* Sparkfun LiPo charger and 5V boost board ([http://www.sparkfun.com/products/10300]) |
|||
* USB A to micro cable (micro has a tiny end) |
|||
* RC servo motor |
|||
* 3 axis accelerometer ([http://www.pololu.com/catalog/product/1246]) |
|||
* 8ohm speaker ([http://www.sparkfun.com/products/10722]) |
|||
* Pushbutton |
|||
* Flex sensor ([http://www.sparkfun.com/products/10264]) |
|||
* Force sensitive resistor ([http://www.sparkfun.com/products/9375]) |
|||
* Breadboard |
|||
Also available are 5mm super bight LEDs in blue, red, green, yellow and white, IR LEDs, IR sensitive phototransistors, red sensitive phototransistors, small RC servo motors, and tiny vibration motors. |
|||
The Mechatronics Lab has 6 workstations, each with power supply, multimeter, function generator, oscilloscope, soldering iron, wire, wire strippers and cutters, solder, and a PC with the Arduino software installed. The white cabinets contain resistors, capacitors, potentiometers, and a variety of useful ICs. |
|||
You can learn more about the Arduino on the website [http://www.arduino.cc/] |
|||
You can download the Arduino website for PC, MAC or Linux at [http://arduino.cc/en/Main/Software] |
|||
A nice Arduino tutorial is at [http://www.ladyada.net/learn/arduino/index.html] (uses a slightly older version of the Arduino board, but otherwise is fine) |
|||
The [[Media:NU32v2_stripchart.zip | NU32v2 Stripchart plotting tool]] is useful for plotting data on your computer. |
|||
Here is the code on the demo Arduino : |
|||
<pre> |
|||
/* |
|||
Example Arduino code for NU EDI Bootcamp 2011 |
|||
Pins used: |
|||
0 - serial rx, hardwired on the board, so don't use it for anything else |
|||
1 - serial tx, hardwired on the board, so don't use it for anything else |
|||
2 - button |
|||
5 - pwm for blue led |
|||
6 - pwm for yellow led |
|||
7 - vibration motor |
|||
8 - speaker, for use with tone() function -> this will mess up |
|||
pwm on pins 3 and 11 |
|||
9 - pwm for the rc servo |
|||
A0 - accelerometer X |
|||
A1 - accelerometer Y |
|||
A2 - accelerometer Z |
|||
A3 - flex sensor |
|||
A4 - pressure sensor |
|||

</pre> |
|||
The functions you can use in your code are listed at [http://arduino.cc/en/Reference/HomePage] |
|||
You can power your Arduino off USB power while testing, or using the 3.7V LiPo battery with the LiPo Charger/Booster board to go mobile. From the Boost board, connect GND to the Arduino ground, and VCC to the Arduino 5V. |
|||
'''WARNING 1''' Do not connect the USB and battery to the Arduino at the same time |
|||
'''WANRING 2''' Do not pull the battery out of the charging board by the wires, try to pull it out by the white plastic connector |
