Intro: Arduino Bluetooth Robot Face
This is a very basic design of a robot face made of 2 OLED's and a servo controlled over bluetooth from a smartphone. I am working on a robot and i wanted develop a simple start of controlling they facial features. i added the bluetooth to see the different features at the push of a button. With this instructable you will get a very basic view of a simple way to do this and a good platform to build from for your own future projects. This is my first tutorial so its probably going to suck but ask any questions you would like in the comments. Also i am fairly new to the world of electronics so if my stuff is jacked up please let me know thanks.
and yes this is my bed save the comments
Step 1: Parts You Will Need
1: arduino uno
2: 128x64 OLED
1: h2-06 rs232 bluetooth transiever
male breadboard pins
power supply (i used ELEGO 5v/3.3v regulator)
BlueTerm android app
Step 2: Wire It Up
sorry no fancy pictures of the diagram but...
for the OLED's:
SCL to A5
SDA to A4
VCC to 3.3v
GND to ground
for the SERVO:
Brown wire to ground
Red wire to VCC
Yellow wire to arduion PWM 3
VCC to 3.3 volt
GND to ground
RX to arduion TX
TX to arduino RX (disconnect rx and tx while uploading code to arduino)
Step 3: The Code
Feel free to play around with the code like i said before this is a simple preview of what is possible. aslo check out other codes for the OLED's to give add different eyes and gestures like rolling eyes or mad eyes.
once the code is uploaded and the app is installed you can connect to the bluetooth device if you are asked for a passwordit is 1234.
pushing a 0 on the app will give you the instructions you need to make the head move and eyes blink(only thing i have included in this tutorial). it is possible to add another servo for an additional axis on the robot. also share what you have made in the comment below, i will be updating this post as i progress myself.
