Hey guys! i recentlly written a code for patient health monitoring system using arduino and configured with that thingspeak api so that i could collect the data gathered by my pulse rate sensor and temparature sensor to thingspeak cloud and things went very fine my programe is executing fine but the data is not coming on thingspeak cloud..please guys it's so urgent for me cause i have to show this project as mu finao year demonstration project please help me or call me my email is durgeshc1402@gmail.com and call me on 7355104033.. it's so urgent for me to get this project working . below is the code
