Bluetooth Controlled Robot
hi
i am ajay i would tell you how to make your own app as well as your mobile app in a very easy way.
so i will first tell you how to make your own app
How to Make a Bluetooth Control Robot App Using Mit App Inventor 2
hi
To make your own app you just need a gmail address to log in and follow the video i have connected
shortcut: you can download from gallary ,search"robogear " app in mit gallary app.
Part Require to Make It.
hi
the parts you require is
1.arduino
2.l293d
3.pcb
4 ic 7805
5 hc 05
6 1000uf/25v capacitor
7 4pc bo2 dc motor+wheel
8 foam sheet
9 soldering iron
10 drilling machine
The Whole Process How You Will Make It.
hi
here is a video how you can make the whole robot.
The Arduino Code
hi
i am pasting the whole code here you can copy and paste in your arudino .
if motor is moving reverse just change the pin no in first 4 lines of code.
