Introduction: Arduino & Bluetooth Controlled Robot Car.
This is my first project with Arduino uno. In this tutorial I'll show you how you can control a robot car via Bluetooth with my brand new android app. It's called "BlueArd" and it's the 0.1 version. I want to upgrade my app later and add more features.
Step 1: Required Parts/components
1.Arduino uno with USB cable.
2.Bluetooth module HC-05.
8.Jumper wires 20 M-M.
10.Nuts & Bolts.
11.1× smart phone.
Step 2: Schematics.
Make all the connections as shown in the above figure.
note that Bluetooth module RX is connected to TX of the Arduino and the TX to RX of the Arduino.
