Tried to get a second known working Arduino uno board to do a simple output to turn on a known working relay shield on and off. In HS it shows connected but it will not control the relay. When the board boots the relay comes on and stays on. Tried inverting the output had no effect still does not work.
i have also tried 3 LED's to PWN pins to setup an RGB LED and that did not work on a UNO or a MEGA
I have tried servos on MEGA, UNO, and NODEMCU, API and NON-API does not work.
The first board and only board i have got to work was a MEGA to light up single LEDS.
Are these know issues? any one else having these issues too?
