Arduino Bluetooth Module HC-05 With Andriod

ArduDroid: A Simple 2-Way Bluetooth-based Android Controller for Arduino

REQUIREMENTS

• Breadboard wiring and electronics skills.
• Arduino Uno.
• HC-05 Bluetooth serial module.

INTRODUCTION

ArduDroid (formerly Andruino) is a simple tool to help you control your Arduino (or clone) from your Android phone. It's both an Android app and an Arduino program. ArduDroid has a simple Android user interface to 1) control Arduino'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. Please see comments section for users who tried other Bluetooth modules with this app.

Arduino With HC-SR04 Ultrasonic Distance Sensor

Hc-SR04 Ultrasonic Distance Sensor

In this instructable I will show you how to make an ultrasonic sensor (hc-sr04) that measures distances up to 200 cm.

Step 1: Parts And Tools

 

These are the parts and tools needed to make this project:

LED Cube Using Arduino With CODE

The 4x4x4 LED cube (Arduino)

In this instructable I will show you how to make a 4x4x4 LED cube that will be controlled by an Arduino Demulionove. now yes you might say" that Arduino has only 14 I/O pins well also the 6 analog pins can be used as pins 15,16,17,18,19,20. that way giving us enough pins (16 columns + 4layers = 20 I/O pins)

This instructable is made for those who know how to solder (well) and how to program the Arduino. Also I will be providing detours to skip sum steps so if you see (Detour available skip to __ Step) you can follow if you are to lazy to do that.

Arduino With Speaker

Playing Wave file using arduino

This is a simple circuit to play wav files using arduino Nano V3.0 ,it consist from 4 buttons ,each one play specific wav file loaded to SD card.

Arduino Motor Control Via Bluetooth

Arduino - Control DC Motor via Bluetooth

Hi guys,

In this project we will control a DC motor with a smartphone via bluetooth. This project is great to learn more about:

-DC motor

-Interfacing Arduino with your smartphone

-Bluetooth module

-L293D

Connecting a 12V relay to Arduino

Connecting a 12V relay to Arduino

To connect a 12V relay to the Arduino you need the following things:

- 1 Arduino

- 1 diode for example 1N4007

- 1 NPN transistor for example 2N2222 (in the US) or BC548 (in Europe)

- 1 relay for example one with coil voltage 12V and switching voltage 125VAC/10 A

- 1 multimeter

How to program ATTINY 45/85 with Arduino

Program an ATtiny with Arduino

Follows are directions for programming the ATtiny microcontrollers using the Arduino IDE. In plain English, this is how to program 8-pin Atmel chips as you would normally an Arduino. This is cool because the ATtiny is tiny, and - well - this allows you to make tiny things that don't need a big ol' microcontroller.

The instructions I have posted here are pretty much the same as instructions given by the incredibly awesome High-Low Tech Tutorial. I posted my version of the instructions here because I plan to make a couple of upcoming projects using ATtiny chips and figured I would show my process.
