hi,
This program is used for reading and generating an analog signal, for this purpose, a digital to analog converter 8 bits is necessary "DAC0800"
when I measure the voltage at the output of the DAC with a multimeter voltage varies from about 2-4 volt orderly
but when I use the arduino to measure this analog voltage, the voltage varies in a disorderly, I do not know why!
i want to know if my program is correct!
