can you connect U1 to U2?

@copilot can you connect U1 to U2?
2y
Sure. Here's how you can connect the MAX7219 (U1) to the Arduino Nano Barebones (U2):
  1. Connect DIN of U1(MAX7219) to D11_COPI (MOSI) of U2(Arduino Nano Barebones).
  2. Connect CLK of U1 to D13_CLK (SCK) of U2.
  3. Connect LOAD of U1 to a suitable digital pin on U2. You can select any available digital pin on the Arduino. For example, you could connect it to D2 or D3 etc depending on your requirements and if those pins aren't used elsewhere.
  4. Connect GND of U1 to GNDTERMINAL of U2.
  5. Connect V+ of U1 to 5VTerminal of U2.
This connection scheme allows the Arduino (U2) to control the MAX7219 (U1) via SPI communication.
Please follow the above scheme and your Arduino Nano Barebones (U2) should be able to control and send data to the MAX7219 (U1) for driving 7-segment numeric LED displays or individual LEDs appropriately.
Note: Please ensure that the power requirements and voltage levels of all components are compatible to avoid damage to any connected devices. The MAX7219 and Arduino Nano both operate at 5V.

Assuming you want to use the SPI communication protocol for connecting MAX7219 (U1) to the Arduino, here is how to wire it up:
  • Connect U1:13 / CLK (Clock pin) to the Arduino SCK pin.
  • Connect U1:1 / DIN (Data Input pin) to the Arduino MOSI pin.
  • Connect U1:12 / LOAD (Load/Chip Select pin) to one of the Arduino digital IO pins, for example D10.
  • Finally, make sure to connect the grounds of both U1 and Arduino together to establish a common ground.
Also note that you need separate power supply connections for U1 and Arduino, be sure to connect U1:19 / V+ to 5V and U1:9 / GND to Ground.
If you have a different Arduino and interface (e.g. I2C, UART, etc.) in mind or need to use specific pins on the Arduino, please provide those details so I can update the connection guidance accordingly.
