Raspberry Pi Java ME 8 Tutorials with Adafruit components #piday #raspberrypi @Raspberry_Pi
Thanks to Jose for sending in these tutorials he posted in the oracle community.
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
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
