So we can use a simple formula for routine calculations: “level = 255/5 x effective voltage” The experimental code for ATtiny85 is the same as the Arduino Sketch, as indicated. The only deviation is ...

The PWM sketch works to vary the output linearly, however, the light outputted by the LED does not change in a linear manner. When applying the scientific metric of ‘perceived brightness versus time’ ...

At first glance, an Arduino library for LED control might seem superfluous, but if you are interested in nice effects, the coding for them can be a bit onerous.

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
