Hey, I am having troubles with my DMX shield on top of my arduino uno. My installations consist of the following parts: Temperature sensor, LCD, DMX shield and LED lighting. When I use my arduinog without the DMX shield I can read the temperature on the LCD. But when I put the DMX shield on top of the arduino and connect the wires on the same place I get strange characters that don't exist. I am still able to control the LEDs so that is working fine but I cannot read the temperature of the display.
Someone having an answer for me. I am still pretty new with this and don't mind the wiring it is a bit of a mess.
Thanks in advance!
