thingiverse

OTTO robot with WHEELS List of parts: * Arduino NANO with I/O shield * Small female to female jumper wires * Buzzer * Futaba servo 9G continuous rotation x2 * HC-SR04 Ultrasound sensor * MAX 7219 LED matrix * Nuts M3 x4 * Screws M3x12mm x4 * Powerbank (optional) or just use the USB for power the Arduino board. I used a 3.7V 1200mAH LIPO and DC to DC booster Check the OTTO Plus for connections as this is based on this, using D2 and D3 for the left and right wheel servo's. The HC-SR04 Ultrasound sensor is not connected in the schematic; trig for pin 8 and echo for pin 9) Code and libraries are : https://github.com/jarsoftelectrical/OTTO-Wheeled For the programming: Download & Install Arduino IDE: https://www.arduino.cc/ This project is still under development, I will continue to convert the Bluetooth code for use with the Zowi app. https://github.com/jarsoftelectrical/OTTO-Wheeled/blob/master/20170827_200142_mpeg4.avi
