I was in search for a cool project to do with Arduino Microcontroller and I came across this little robot
Although there is detailed information on how to build one in the above link I found it quite confusing with the variety of the files versions and decided to bring here a clear version that works for me with some modification I made and include:
New head to fit better the sound sensor, Ultrasonic sensor, Arduino nano+Shield with holes to Voltage and mini usb
New Body with customize space for on/off switch, USB charger,18650 Li-Ion battery and LED matrix
Just to clarify that I'm not the owner of the Arduino files, App and the idea ownership is from the link above
Download OttoDIYAPP_121.zip Extract the zip and install the APK file in your Android phone
Upload the Libraries from the zip to Arduino IDE - Don't know how? Follow this
Open OttoDIYAPP_121.ino with Arduino IDE search for the line Serial.begin(19200); and change it to the baud rate on your HC-06 Bluetooth module! If you didnt touch it from factory the default is 9600. So change it from 19200 to 9600. It should look now Serial.begin(9600). compile and upload it to your Arduino
Now enable your mobile Bluetooth and search for HC-06, pair it!
Open the App in your mobile and press "Find Otto+" on the blue bar, search for your HC-06 and connect Enjoy (:
