Follow this link and it will help with making the buttons work - then couple it with the sensor readings to be displayed. Note the \>return 200 value in the photon code doesn't do anything in App inventor. > [@Connect Spark core with Android App made in Appinventor](https://community.particle.io/t/connect-spark-core-with-android-app-made-in-appinventor/7378/5): > > HI Jozef Sorry to hear you are still having trouble. I am also sorry for the delay in response. Ok, lets get you started with this. Try flashing this firmware on your spark //Initialize define ON 1 define OFF 0 int Pin0 = D0; //Define your pin int OUT1State = 0; //This variable maintains the current state of the Pin0 void setup() { pinMode(Pin0,OUTPUT); Spark.function(“pin0”, OUT0); //This is the function that gets executed when there is a matching API request // Initialize low dig… hope it helps, if not I will post what I have working --- _[View the full topic](https://community.particle.io/t/mit-app-inventer-2-button-control/21661)._
