Hi, I'm still a newbie in Arduino and have to build a device for my final year project at uni.
To begin with, I need to connect a GY-273 (HMC5883L) and ADXL345 sensors to get input to my Arduino UNO board. However, I do not know whether it is safe to simply connect the respective pins to the board. I've read about multiple sensor connections and learnt that there are methods called I2C and SPI for this purpose. Is it applicable for my sensors, or is there a a different approach?
I would be extremely grateful if you could help me with this question.
