Sensor Graph arduino with CDS :: Arduino Android Shield : Using AppGosu ADK

Sensor Graph arduino with CDS 
     :: Arduino Android Shield : Using AppGosu ADK

Direct android programming Using Arduino
Don’t need android SDK, use only arduino

Function :
CDS circuit detects the light.
Arduino : ADC, transmit the data to AppGosu module.
AppGosu : draw the graph in Android phone



Step 1 :  Install
1. AppGosu :: Arduino-Android Library from GitHub   for Arduino
2. Install the app, AppGosu for android shield from Google play
3. Connect AppGosu PRISM Module to Tx pin in Arduino  at www.ebay.com

Step 2 : Circuit
 

(connection)

//===  serial event From android phone  ======================
void serialEvent() {

    if( app.eventButton(11)) {

    }
    if( app.eventButton(13)) {
        line_color = 13;
        app.stroke(255,0,0);
    }

//===  For android program  ======================
