Figure 1- Result with the low pass filter, analogue write loop cycle from 0 to 255 and 255 to 0.
Figure 2 - Low pass filter used
The filter was used with a pwm frequency of 200kHz.
Figure 4 - Pikachu figure
Figure 5 - Pikachu contours with the galvanometer
There is a problem with the leg of the pikachu but its possible that this problem was created when the coordinates of the leg were being copied to the arduino, since the rest of the shadow is ok. The image looks different from the figure 4 because of the scale.
It is expected an update of the work every week.
