Hello, I live in Brazil and I bought the pixy cam, I want to connect it on my Arduino MEGA but I don`t have the cable to do it. What I can do? I don’t know if I can find this cable in my country, so I want to know if I can do something to connect them without this cable. Thank you!! 
Hello Matheus,
Pixy comes with an Arduino cable that should work with the Arduino MEGA. (The MEGA has an ICSP port.) Did you misplace the cable?
There is also some information here if you want to make an Arduino cable:
