Build an electric car with Arduino and Bluetooth control or IR (infrared)

Infrared Version: Electronic Car, mounting hardware and demo


You can easily create a project with Arduino electronics to create a car with infrared control without cable! Objects used for this project:
colored LEDs.
1 servo motor.
1 Arduino development board.
1 ProtoShield extension.
4 engines.
1 bluetooth device
1 distance sensor detector
resitences, jump cables and 1 USB power cable.

Version smartphone: Electronic Car, mounting hardware and demo



You can easily create a project with Arduino electronics to create a car with Bluetooth and order it with your smartphone without cable!
