+Updated 15-12-2017
+
+The program main focus is now to function as a heartrate monitor, the device itself beeps and blinks when it registers af heartbeet via the earclip sensor.
+The idea it to send the hearrate and the timestamp via et tcp socket to a python server running on a server and then processing the data and storing in a database
+
+The following sensor/addons should be attached to the shield/board for the program to work as intended. 
+A0: Heartrate monitor
+A3: Temperatur sensor
+D3: Buzzer
+D4: LED
+If using the motor it should be attached as following: Normal pins to D8, D9, D10, D11 and ground VCR
