GROSIR KAOS POLOS & KAOS MURAH
project ini dibuat berbasis uC AVR ATMega8535 dengan tampilan LCD 16×2 dan menggunakan bahasa C CodevisionAVR sebagai kompilernya. PORTA.0 di set sebagai pin SDA dan PORTA.1 di set sebagai pin SCL.
berikut ini adalah potongan sourcecode dari project sensor suhu ds1621 :
