Android Arduino Speech recognition

Arduino with voice commands using an Android Mobiles Before we make a voice activated home automatic system

More details Watching this vedio


Thing that you'll need:

- 5 LED Indicators (the color of your choice)
- Arduino UNO (a clone works fine)
- HC-05 Serial Bluetooth Module
- Solderless Breadboard
- Jumper Cables

Multi Servo Motor Control with Arduino and Android app

Android app using MIT app inventor 2 , I created this app to control 6 servo motor using android and arduino, I have arduino uno, which has only 6 PWM pins that's the reason I created 6 servo control, If you want to control more than 6 you can use arduino Mega to do this Need for Components - Arduino Board - HC-06 / 05 Bluetooth Module - Servo Motor x4 - Wires and Breadboard - Battery - Android Device You can find the Circuit Diagram for this project above. Connect your servo according to that, If possible power the Servos and arduino separately Check the video below to know How to make mit app for controlling multiple stepper motor. - MIT App Inventor site to create an application. http://appinventor.mit.edu/explore/

Buetooth based stepper motor controller by arduino The Stepper motor used here is a rusty old EPOCH (5 wires) stepper motor, which is a unipolar stepper. '  Requiredments : - Bluetooth Module ( for example : HC05 or HC06 ) - Jumper Cables Checkout the video to know how the app control stepper motor Source code for controlling stepper motor from android app: ------------------------------------------------------------------------------------------------------------------------------- #include <AccelStepper.h> AccelStepper stepper(AccelStepper::FULL2WIRE, 8, 9); int spd = 1000;    // The current speed in steps/second int sign = 1;      // Either 1, 0 or -1 void setup() {    Serial.begin(9600);   stepper.setMaxSpeed(1000);   stepper.setSpeed(1000);    } void loop() {    char c;   if(Serial.available()) {     c = Serial.read();     if (c == 'f') {  // forward ...

Course on MIT app inventor Arduino For Andriod Creating Andriod apps using MIT app inventor and connected the app with arduino to make things work, I often get email stating something went missing when they follow my tutorial, Here's a step by step tutorial on getting started with creating MIT app inventor and control things with arduino Technolgy 1. App Inventor: How to Make an Android App - The Basics In this tutorial, I show you the basic concepts of Google App Inventor. Keep watching this series to learn many advanced features of the software. Remember, the things I go over in this video are essential to learn before building up your knowledge. 2.  Getting Started with Arduino and Android   MIT app inventor and what are the requirements need to get started with this video series, anyone watching this video can make their own app and control a LED connected to arduino without any prior experience Blinking an LED is the first thing we...
