Learn how to connect sensors to the Raspberry Pi and control them with Java.

Part 1 of this series explained how to connect electronic sensors to the Raspberry Pi Model B using general-purpose input/output (GPIO) interfaces. (That article and the rest of this series also apply to the Raspberry Pi Model B+ or the Raspberry Pi 2 Model B.)

This article focuses on using inter-integrated circuit bus (I2C) interfaces to connect sensors, and it shows examples of how to develop Java ME 8 classes that can do the following:

• Control servo motors using the Adafruit PCA9685 16-channel 12-bit pulse width modulation (PWM) servo driver
• Detect light and object proximity using the VCNL4000 proximity/light sensor
• Measure temperature and humidity using the SparkFun HTU21D humidity and temperature sensor
• Create an electronic compass using the Honeywell HMC5883L digital compass module
