servo resetting LCD?
Archiver
Posts: 46,084
Hi,
I have a continuous rotation servo from parallax, a motion sensor and a 4
lines serial LCD connected to a BS2. My program continuously sends some data
to the LCD and the sensor takes care of triggering the motor. My problem is
that the stamp seems to reset every time that I send a pulsout to the servo.
Any ideas on why that's happening and how I can solve it? I tried using a
second power supply to power the LCD, but that didn't work at all...
Thanks,
Marcelo.

The separate supply will probably work too -- be sure to connect the
grounds together.
