Be aware hat both R_EN and L_EN must be connected to set(high) GPIO pins. This is done in die dc_init() function.

\#define MIN_UPTIME 150 and \#define MAX_UPTIME 300 can be used to calibrate the servos to a new minimum and maximum position and therefore it should be no problem to also use other servo models with this library.
