i2c communication

Post by alif » Thu Jul 14, 2016 9:30 pm

I am trying make my lilypad arduino usb the master and huzzah esp8266 slave, but after uploading the codes on both boards nothing comes up on the serial monitor. i have tested the lilypad arduino usb with an arduino uno and it works perfectly.
Pins
Lilypad-2=2-Huzzah esp8266
Lilypad-3=14-Huzzah Esp8266
Lilypad-+=3v-Huzzah Esp8266
Lilypad--=GND-Huzzah Esp8266
is there anything i'm connecting or doing wrongly.
