+# VaporizR2
+It was a Nikko VaporizR2 RC toy. Dead one. So I removed all parts except motors, battery block and switch. The idea is to control it with Arduino from Android over Bluetooth.
+## Parts
+1. Arduino Uno R3
+1. Sparkfun Motor Driver ([library and examples](https://learn.sparkfun.com/tutorials/tb6612fng-hookup-guide))
+1. HC-05 Serial Bluetooth Module
+1. PP3 9-volt Battery
+## Source code
+In source code you can find:
+* an Android app to control the car
+* a [Fritzing sketch](/estevez-dev/VaporizR2/tree/master/Fritzing) to build hardware
+* an [Arduino sketch](/estevez-dev/VaporizR2/tree/master/Sketches/bluetooth_motor)
+## Car hardware
+![image](https://github.com/estevez-dev/VaporizR2/blob/master/docs/VaporizR2_bb.png?raw=true)
+## Android app
+It is a simple app with two sliders to control left and right weels that sends commands to Arduino via Bluetooth serial.
