INTRODUCTION

GET IT ON google PLAY "ardudroid" app

ARDUDROID (formerly Andruino) is a simple Android app to help you control the pins of your Arduino Uno (or clone) from your Android phone wirelessly. It's both an Android app and an Arduino program. ArduDroid employs a simple Android user interface to 1) control Arduino Uno's digital and PWM pins 2) send text commands to Arduino 3) and receive data from Arduino over Bluetooth serial using the ever popular and really cheap (less than $10 from ebay) HC-05 Bluetooth over serial module.This app has been tested and designed for the HC-05 Serial Bluetooth module. Other Bluetooth modules may or may not work. Also, while I used Arduino Uno in this prototype, feel free to experiment with other models of Arduino. I have published a guide before on building and programming a circuit with the HC-05 Bluetooth module and Arduino but I will briefly describe again in this guide how to wire the circuit using a breadboard and jumper wires.Special thanks to engineer Jafar Quttaineh for testing the app and for his invaluable input.

How to use ArduDroid


You can use ArduDroid to send commands to Arduino to control a relay to turn electric gadgets on/off, control a robot servo, increase/decrease speed of a motor and reverse direction, dim a light, speed up a fan, and so on. Furthermore, you can read Arduino pins and sensors then transmit the data back to your android phone.

I would like to thankful to Techbitar as great instructables.

Step 1: Arduino Standalone

After I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Uno and put it on my own circuit. This would also free up my Arduino for future projects.

The best instruction I found is http://arduino.cc/en/Main/Standalone

  • A breadboard22
  • AWG wire7805
  • Voltage regulator
  • 2 LEDs
  • 2 220 Ohm resistors
  • 1 10k Ohm resistor
  • 2 10 uF capacitors
  • 16 MHz clock crystal
  • 2 22 pF capacitors
  • small momentary normally open ("off") button, i.e. Omron type B3F

Step 2: Making the Electric Components

"Fritzing is an open-source hardware initiative that makes electronics accessible as a creative material for anyone. We offer a software tool, a community website and services in the spirit of Processing and Arduino, fostering a creative ecosystem that allows users to document their prototypes,share them with others, teach electronics in a classroom, and layout and manufacture professional pcbs."

I am using Fritzing software program to see the images showing you how to hook up the wires and electric components. I rather to making by the hands.

what do you need is

  • 12 volts power plug
  • 12 volts RGB led strip
  • Bluetooth module HC-05
  • voltage regulator 7805 (for bluetooth and Atmega)
  • 3 MOSFET N channel (each for red,blue,green led)
  • 3 150ohm (led strip)
  • 1 1k ohm (bluetooth)

I would like to a special thanks to adafruit It explained very well. That how I learned from them.

Step 3: Time to Code!

I have share the codes with you. I hope you can download it from your computer. either way you can go to Github. My github account is Github. Please help me to improve the codes if need. I created the custom between the values from 0 to 255. When press the number square 13 on the app smartphone will send the output.

I am put each switch case groups of colors in the order.

if you want full red so its 255,0,0 ,

if you want full green so its 0,255,0 ,

if you want full while so its 255,255, 255,

if you want full purple so its 85, 0, 85,

etc.

Step 4: Finally Project

I was very happy with an awesome project communicate with Bluetooth to control them by the app smartphone. I really love about press on the square between from 13 to 5. at same time I am a little disappointment with my codes because when I press switch case for 13 and I had to wait for them to be done for while 100 time loops so I decided to make use an External Reset Button with Arduino if i want to change the switch case. its very nice its have An extremely simple reset circuit. no code necessarily. but for now I will fix the code later. the most important is they are working great
