确保您更改了ONEWIRE_TO_I2C_ROM1和ONEWIRE-TO_I2C_ROM2定义的地址,使您的单总线地址与I2C地址相匹配。 注意:如果您使用USB端口来给Arduino Nano编程,您必须断开它与IO扩展器的连接,因为它也使用相同的单一串行端口,相反,如果您想调试使用ICSP端口来编程ATmega328P。要启用软件调试端口,请取消对SERIAL_DEBUG定义的...
Temperature Sensor(used inArduino Sous Vide Cooker): Magnetic Sensor: Gas/Methane Sensor, this is theTwittering office chair: Step 16: Arduino MIDI IN Finally, you can send MIDI into the Arduino and use it to control things connected to the Arduino's outputs. Here's arobotic drum kit, mad...
Interface Groove Temperature Sensor With Arduino UNO: In this project Arduino is used with Grove temperature sensor to measure the temperature present in the atmosphere and RGB LCD is used to display current temperature on the screen.
Arduino sketch: receiving temperature data and publishing on an LCD. The code for the LCD sketch mirrors the one used for the sensor: Nocan.lookupChannel looks up the channel identifier cid of the channel named "temperature". Nocan.subscribeChannel instructs the network driver to listen to al...
