Hello I make a greenhouse, Bluetooth module and I will control this house with my mobile phone. I made an Android app and this app sends the numbers to Arduino Serial. My problem is saving these values. For example if I sent temperature 20º Arduino recives 2 series of numbers 88(temperature code) and 22(the temperature). How I can do if arduino receives 88 22 it saves in variable temp the number 22.
Sorry for my English I'm a Catalan student and I need to improve this.
