2. Arduino UNO hardware Microcontroller: Atmega328 Operating Voltage: 5V Input Voltage (recommended): 7-12V Digital I/O Pins: 14 (of which 6 provide PWM output) Analog Input Pins: 6 DC Current per I/O Pin: 40 mA DC Current for 3.3V Pin: 50 mA Flash Memory: 32 KB Clock Speed: 16 MHz http://arduino-info.wikispaces.com/QuickRef#pwr\

3. Sample code Sensor Pin is defined as analog pin 0 Function returns no value; Starts a program and sets initial values Baud rate is 9600 Prints data to the serial port; Reads the value from specified analog pin Pauses for 2 ms http://www.youtube.com/watch?v=10-tkg5Qe9c

4. 3 ways to visualize the result

5. Touch shield for Arduino 2.8” diagonal color touchscreen TFT 240x320 resolution, 18-bit (262,000) color High speed SPI display with digital SPI touchscreen driver The display uses digital pins 13-9 Touchscreen controller requires digital pin 8 http://www.youtube.com/watch?v=3exmQfjo-P8

6. MATLAB Real time signal acquisition and processing Ex. Real time plotting of distance on MATLAB using Arduino Uno & PING http://mechatronicstutorials.blogspot.com/2014/06/real-time-plotting-of-distance-on.html
