您有一个微控制器和两个相同的传感器，这意味着它们具有相同的I2C地址。如果没有多路复用器或配置传感器的I2C地址的可能性，则无法将它们连接到相同的I2C总线。然而，Arduino Uno R4 Wifi在板上提供多个I2C总线。一个I2C总线在引脚上可用，另一个在Qwiic连接器上可用。

The Grove – I 2 C High Accuracy Temperature Sensor (MCP9808) is a pretty cute module based on MCP9808. In addition to high-precision temperature measurements, the module also offers a programmable ...

The latest board from the team enables you to have up to 4 I2C busses connected to either your Arduino development board or Raspberry Pi mini PC and is also equipped with Grove Connectors and LEDs.

其次，用Grove电缆将两个光线传感器分别连接到Grove Beginner Kit主板上的A2与A6接口；将OLED屏幕连接到I2C接口。 代码实现的功能：当1号光线传感器检测到光线值小于50，并且2号… ...

基于 Freescale 的 MPR121，此传感器拥有12个完全独立的拥有内置自动配置功能的电极。因为它拥有 I2C 接口，您只需一个 Grove 端口就可以检测到所有12个电极的信号变化，并且I2C 的地址从 0X5B 到 0X5D 是硬件可配置的。因此也使得在单个系统中同时使用多个 **Grove - 12 Key Capacitive I2C Touch Sensor V2 (MPR121 ...

更重要的是，这不仅仅只是端口数量的叠加。我们都知道，在同一个总线系统中，I2C设备必须使用不同的地址，即使使用Grove I2C Hub（4或6端口），这个规则依然适用。然而，借助Grove - 8通道I2C Hub，你可以将最多8个具有相同地址的I2C设备连接到同一个Grove I2C系统中。这都要归功于TCA9548A I2C多路复用 ...

This prototyping kit has two Grove I2C sensors but we can only connect one at a time. It would be even better if the kit included an I2C breakout so that two sensors can be connected at the same time.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very ...

Demonstration of a fun little FM radio that can be controlled over an I²C bus. Shown is how to do this in two versions. One with an ATtiny85 to create a tiny radio, with a mini-jack, a trimmer and two ...
