I built a remote control Power Wheel for my 4 year old son, who has cerebral palsy. http://littlebeluga.com/Welcome/TabId/91/ArtMID/729/ArticleID/1/Remote-Control-Power-Wheels.aspx
I would like to upgrade the car to be controlled by an Android tablet that will be mounted in place of the steering wheel. Here is a list of parts currently installed in the car.
2 - 12V 12AH SLA Batteries Mamba Max Pro 1/10 ESC 2" Stroke 150 lbs Force Linear Actuators with Potentiometer Feedback (FA-PO-150-12-2) Linear Actuator Control Board (LAC)
After doing some research, I think these are the parts I will need. Please let me know if I am on the right track...
1 - Bluetooth modem (currently looking at the BlueSMiRF Silver) http://www.amazon.com/SparkFun-Bluetooth-Modem-BlueSMiRF-Silver/dp/B004GTUI76/ref=sr_1_1?s=electronics&ie=UTF8&qid=1386006512&sr=1-1&keywords=BlueSMiRF
1 - Arduino Uno (My understanding is the Arduino board will receive commands from the Bluetooth module, which will take the place of the radio) Note: Since this will be my first time tinkering with circuit boards, I'm thinking about getting this starter kit to learn some of the basics and create a prototype, before hooking anything up to my Mamba Max. http://www.amazon.com/Arduino-Ultimate-Starter-page-Instruction/dp/B00BT0NDB8/ref=sr_1_3?s=electronics&ie=UTF8&qid=1386001870&sr=1-3&keywords=Arduino
For the tablet, I have an ASUS Transformer that will be mounted to the dashboard. The idea is to have arrows on the tablet for him to touch and drive the car on his own.
One thing I am curious about is, will I need an additional Bluetooth modem to control the linear actuator? Is there a Bluetooth modem that is capable of controlling two motors and the linear actuator?
Any help you all can provide is greatly appreciated.
