  1. Low Cost Portable device for collecting behavioral data based on the arduino board Carlos Alexis Pérez Herrera Rogelio Escobar UNAM-Laboratorio de Condicionamiento Operante Project funded by the 2012 saba International development grant and papiit ta300213-2, dgapa, unam.

  2. Recording data • In applied behavior analysismeasurement of behavior is conducted in: • laboratory settings • natural settings. • by the experiments • and by the clients.

  3. Recording data

  4. ARDUINO-BASED DEVICE • Records behavioral data accurately by pressing a button. • Produces visual feedback. • Stores data. • Portable.

  5. The Arduino Board • Arduino is an open source electronicsprototypingplatform • There is a vast community sharing code and information. • It is accurate and portable.

  6. 14 Digital Pins Quartz Crystal USB Jacktype B Microcontroller External Power Supply Output Voltage 6 Analog Pins

  7. Shields • Shields are boards that can be plugged on top of the Arduino board extending its capabilities. • This Sparkfun shield adds a MicroSD card to the Arduino board.

  8. SD Shield and LCd • The arduino writes and reads from a microSD card. • A Liquid Crystal Displays (LCD) allows presenting feedback to the user.

  9. Code • #include <LiquidCrystal.h> • LiquidCrystal lcd(2, 3, 4, 5, 6, 7); • #include <SD.h> • int CS_pin = 8; • int pow_pin = 10;

  10. Device

  11. Data Sheet • CSV File (compatible with Excel and Numbers). • The logic values for each button are updated every 500ms. • Data Sheet and feedback can be personalized for different conditions.

  12. Analyzing Data

  13. Conclusions • This is a portable device that can be used for recording behavioral data in natural or laboratory settings with accuracy. • It generates an easy-to-read data sheet. • It can be assembled easily with no knowledge of electronics • Price<$100 USD. Thank you!
