Hi guys im looking to wire up a sim racing wheel with buttons and the esp32 adafruit i can post the files i have but its free hand drawn and this is my first project
Hi. Welcome to the forum.
Hi @ciscoprtv ,
welcome to the arduino-forum.
well done to draw a schematic by hand.
Connecting the buttons with a matrix can work. Another option is to use an 16 channel IO-expander which is driven by I2C-Bus.
There are multiple chips available for that MCP23017, SX1509. Onlineshops like sparkfun or adafruit have boards that can be connected easily to a microcontroller.
This enables to connect each button to its own channel while the IO-expander-chip is conected through just 2 IO-pins to the ESP32.
please post a detailed description of what you plan to do
This sticky thread helps to cover all aspects that you should include in your description
best regards Stefan
