IFTTT_Button

/*
 * ZOOM RECORDING : https://psu.zoom.us/rec/share/3dFYE7PXtT5JS5X3-ULtcIkYBp6meaa80SRK_PULnRozXKrivk44EH1D91u5EL_C
 * Adapt code so that every time you simulate a button press on Arduino, it reads the values from its onboard accelerometer
 * Send these parameters to an IFTTT maker webhook
 * Event name "accel_readings"
 * Webhook should trigger an email service
