ESP32 & Multiple OLEDs | I2C Expansion with a Multiplexer
I2C Multiplexer ESP32 OLEDs Did you know you can easily connect multiple displays or sensors to just one microcontroller? Welcome back to MaisonUp! Today, we introduce you to a powerful tool—the I2C Multiplexer. When working with microcontrollers, efficient wiring is key, especially for complex projects. That’s where I2C (Inter-Integrated Circuit) comes in! Unlike SPI (Serial […]
