A purpose of this repository is to discuss and document properly the Otto libraries for Arduino IDE.

How do I setup the Arduino IDE and libraries? or How to install the libraries (not Otto specific) ? Answer: "There are multiple ways to add libraries to your Arduino IDE after installed the most easy for me is to just Download all the libraries from the files tab for the specific project and move them to C:\Users\user\Documents\Arduino\libraries (or wherever your libraries folder was installed) Other ways use .zip installation through menu or even automatic updates online(i wish i knew how to do this for Otto) but i never need to do it this way, is a very general topic that all new Arduino users face and there is a lot information by just googling. https://www.arduino.cc/en/Guide/Libraries#toc3»¿

Otto Core Libraries is the code to be deployed to the user's Documents\Arduino\libraries directory, including: BatReader, EnableInterrupt, MaxMatrix, Oscillator, Otto, OttoSerialCommand Different and similar versions of Otto Core Libraries are currently included in multiple repositories and sub-projects:

To resolve the need to maintain so many different deployments/versions here in this centralized repository, in order to maintin consistency along the Otto remixes we stablished a naming structure: Otto_(followed by the component name and version) for example:

• Otto9 contains all the main functions and is the version 9
• Otto_gestures9 contains all the gestures functions
• Otto_mouth9 contains all the mouth functions
• Otto_sound9 contains all the sound functions
• Otto_Matrix9 contains all the matrix functions

Complementary libraries like Ultrasound, Interrupts and BatReader are independent of Otto(they can work with other projects) therefore are just named like they are, for example:

• US contains the functions of the ultrasound
• Bat Reader contains the functions to meassure the battery.
• Adafruit_NeoPixel external library from Adafruit to control NeoPixel LEDs

We will follow these standard connections SERVOS: PIN_YL 2 left leg PIN_YR 3 right leg PIN_RL 4 left foot PIN_RR 5 right foot PIN_LA 6 Left arm if enabled PIN_RA 7 Right arm if enabled

ULTRASONIC: PIN_Trigger 8 //TRIGGER pin (8) #PIN_Echo 9 //ECHO pin (9)

BUZZER: PIN_Buzzer 13 //BUZZER pin (13)

SOUND SENSOR: PIN_NoiseSensor A6 //SOUND SENSOR ANALOG pin (A6)

LED MATRIX:

DIN_PIN A3 //DIN pin (A3) CS_PIN A2 //CS pin (A2) CLK_PIN A1 //CLK pin (A1) LED_DIRECTION 1// LED MATRIX CONNECTOR position (orientation) 1 = top 2 = bottom 3 = left 4 = right DEFAULT = 1

BATTERY SENSE: boolean BATTcheck = true; // SET TO FALSE IF NOT USING THIS OPTION PIN_Battery A7 //3.7V BATTERY MONITOR ANALOG pin (A7)

TOUCH SENSOR or PUSH BUTTON PIN_Button A0 // TOUCH SENSOR Pin (A0) PULL DOWN RESISTOR MAYBE REQUIRED to stop false interrupts (interrupt PIN)

RGB NEOPIXEL LED: boolean enableRGB = true; // SET TO FALSE IF NOT USING THIS OPTION NeopixelRGB_PIN 12 // NEOPIXEL pin DIGITAL PIN (12) NUMPIXELS 1 // change for more than 1, becarefull with the current

SERVO ASSEMBLY: to help assemble Otto's feet and legs - wire link between GND and pin 7 for PLUS & pin 10 for humanoid #define PIN_ASSEMBLY 10 //ASSEMBLY pin (10) LOW = assembly HIGH = normal operation

Contributing to this software is warmly welcomed. There are 3 ways you can contribute to this project:

1. Test and if find a problem then post an issue.
2. Helps us solve the issues or other bugs by commenting
3. Bring missing libraries from other Otto remixes here. You can do this basically by forking, committing modifications and then pulling requests. Please add a change log and your contact into file header.

Thanks for your contribution. Just make sure to keep consistency in the naming and make a record of the change or improvement made. Welcome to the Otto DIY code development team!
