Hi,

I have a problem with the Nanotimer. I´ve successfully loaded the sketch on the Arduino Nano and the wiring is also correctly.
But the OLED does´t show anything.
Could someone help me?
Is it necessary that the the OBDII-adapter is plugged into a car or is it enough that the power comes from the USB?

It is not neccessary to connect the OBD-II adapter to let the OLED light up. Please take a pic of your hardware. If it is the defective of the OLED, we will ship you a new one.
