This project actually has two STM32 blue pill microcontrollers where one act as a master and other act as a slave. The next step is the slave STM32 is connected to a MCP9808 temperature sensor and it measures the air temperature and is connected to the slave STM32 microcontroller using I2C protocol. Then the measured temperature data is send from slave to master using two MCP2551 CAN modules. All this connections are done in a breadboard.
