The Arduino measures the rectified analog value to an integer, and applies the appropriate sign from the supplied bit value. The second circuit takes a variation on the same technique but with two ...

if Pin_D0.value() is 0: Pin_D8.value (0) else: Pin_D8.value(1) Making analog measurements By this point, it is fairly obvious that controlling digital IO with Micro Python is straightforward and the ...

The next logical step was to hook up an Arduino to control the plotter. However, once the device could plot analog values, [Marv] quickly looked for a new challenge.

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...
