Making StairClimbingCar With Arduino Part1

Today I will teach you How to make Arduino Car with bluetooth Module.
Followin lists are we need for our project

1.Arduino Mega

2.6 Motor with Gear

3.Bluetooth Module HC06 or HC05 (any can use)

4.8Channel Relay

5.Android App

First we need to make motor forward or backward with two relay and one battery source. I will explain to step by step with Image and text.

we need to connect of two relay NO(Normally Open) and NC (Normally Close).
Each NO or NC to connect with battery Soruce. And then we need connect Compound(Middle) with two relay to motor.
I showed on photo.(Sorry for my bad english writing skill).

On Figure
I connected NC of two relays with yellow wire and this yellow wire also connected to battery ground(I call black).
And also I connected NO of two relays with Red wire and connected with battery supply 6V.
Green Wires are two wire of motor.
This connection for motor forward and backward with two relay.(In figure I used 4channel relay. In this project you should use 8channel relay. )

I teached wire connection for motor forward and backward.

Well!!
Go to next step.
In this step we need to do connect bluetooth module with arduino.

First I teach how to connect bluetooth module with arduino.
In figure I used Arduino Uno.
We should use Arduino Mega in this project.
Pin off Bluetooth. Pin of Arduino

VCC to 5V
GND to GND
Tx to Rx
Rx to tx

I showed on figure.

And then we need to connect motor with relay and bluetooth with arduino.

We success 50%.

MOST IMPORTANT
Very important is our wire connection and Arduino Program.

I will upload my Program file on my Google Drive.If you want, can you request me from my facebook or [email protected].

Program and Android app any you can use.

Next Post I will teach you How to arduino program and android app for Bluetooth Module (HC05).

Thank You.

Thank you Sir.U Aung Khaing teaching for Two Relay connection theory. Forever respect you.
(I promise I will try the best)
