Sorry I cannot answer that as I have no clue as to what you know. A good starting point is the Arduino Cookbook. To help I need to see exactly what you have in front of you. To assist you effectively, please provide the following:
1. Annotated Schematic: Post a detailed schematic of your setup exactly as you have it wired, showing all connections, including power, ground, and power supplies.
2. Technical Information Links: For all hardware devices in your circuit, provide links to technical information. Be aware that many items in the Arduino/Pi world may have the same name but function differently. Links to sales pages like Amazon often lack the necessary technical details, so ensure the links you provide contain the correct specifications and data sheets.
3. Be Thorough: It’s your problem, and the more precise and detailed information you provide, the faster we can help you troubleshoot. This saves everyone time and helps us give you the best possible assistance.
