Hi. All. I am having a problem with reading analog signal through analog pins to my macbook pro.
I have a Mega 2560 and a third part duelmilano. I tested both on a windows machine of reading sensor voltage from analog pins. Input voltage is around 2v - 3v.
But if I use my macbook pro (Lion system 10. 7.4). Every time I connected the sensor output to an analog input. The voltage jumps to more than 5 v straight away.
Is that something wrong with the driver?? Because with the same codes, everything works fine on my pc desktop. But unfortunately, I have to use my laptop with arduino because of other software reason. And both of my arduino boards are having the exact same problem.
I use the latest version FTDI driver for 64bit MAC OS: version 2.2.17
Many thanks to you all
