PIXELIZARD Apps

This android app can establish aconnectionwith any Arduino/microcontroller project that has aBluetoothmodule interfaced! It allows the user to connect any kindsofBluetooth module like HC-05 and HC-06. For most of the modulesthedefault pin for connecting is “1234”With this app you can easy connect and send data toyourmicrocontroller. The app will itself guides you to thecontrolscreen. Still if you are too busy you can read below to knowallpossible controls1. Open the APP2. Click the next button from the open screen3. Now turn on you Bluetooth and pair the device you wanttocontrol. E.g. you paired your HC-05 which is connected toyourArduino.4. Then click “Yes, I understood” and you will be taken tothecontrol screen.5. In the control screen click the “connect” button and selectyourdevice6. Now whenever you press one of the four keys it will send adatato your Arduino/microcontroller board.7. With the “Speed” slider you can also sent analogue values.E.g.you want to control speed of a car8. If you want to send custom values to your microcontrollerclickthe “Tools” icon named “Set Keys”.9. From there you can set values for each of the four keys andclickthe “Tools” icon again.Done! Now it’s time to control your project wirelessly.Arduino code to receive the data#includeSoftwareSerialbluetooth(10, 11); // Connection pins for bluetoothRX& TX.//I used software serial so that you can upload the code evenwiththe bluetooth module connected.intrecieved;void setup() {pinMode(13,OUTPUT);Serial.begin(9600);bluetooth.begin(9600);digitalWrite(13,0);}void loop(){while (bluetooth.available()) { // Recieves Data from bluetoothandstores in recieved variablerecieved = bluetooth.read();Serial.println(recieved); // Prints the last recieveddata.delay(50);}}Soon I’ll upload the link of the tutorial “How to controlyourMicrocontroller with smartphones over Bluetooth ” I havewritten.Or you can check www.tutor.robogearsbd.com for tutorialsIwrote.This is app was developed for learning purpose. The platformusedto develop this app was MIT App Inventor 2.If you areinterested tomake and app like this I can help you with the filejust mail me [email protected]. If you can edit thisapp and make abetter version of it please also let me know and ifyou want I willalso share your app so that other can get benefitedor developfurther and you name will be included as acontributor.Follow me on Facebook:www.facebook.com/ILivetoCode .Please don’t forget to give your reviews,Thank You.
