After persevering with three hours of diligent assembly work every night, i have successfully assembled a display consisting of 16 units and 256 pixels. The calibration process for all these servos has been quite challenging, but i will keep pushing forward, envisioning the final outcome.

The calibration involves determining the PWM control values for the left maximum, center, and right maximum positions. The intermediate values will be calculated and controlled using linear approximation.

On the upper-right panel, i have experimentally attached a mirror panel. I have secured it with a magnet sheet to facilitate the exchange of panels and achieve various visual effects.

The current major challenge is that the size of the work desk is completely insufficient. :-)
