This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

应用设计中，用一条I2C总线驱动多个I2C设备师很常见，实施也很简单，本项目将连接以下I2C设备： Adafruit_GFX, Adafruit_SSD1306.h 和 SPI.h，控制SSD1306 128×32 OLED显示屏。 由于所有元件相距不远，没必要I2C总线使用上拉电阻，因为这些杜邦线就是组件的一部分。 本项目 ...

I2C(Inter-Integrated Circuit)总线(也称 IIC 或 I2C) 是有PHILIPS公司开发的两线式串行总线，用于连接微控制器及外围设备，是微电子通信控制领域广泛采用的一种总线标准。它是同步通信的一种特殊形式，具有接口线少、控制方式简单、器件封装形式小、通信速率较高等 ...

Adafruit has this week announced the arrival of the new Arduino compatible TCA9548A I2C Multiplexer to their online shop, which is now available to purchase priced at $6.95. The latest breakout board ...

For Christmas, [Lior] received a Baofeng UV5R radio. He didn’t have an amateur radio license, so he decided to use it as a police scanner. Since the schematics were available, he cracked it open and ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...

– Small size: As small as a thumb(20×17.5mm) for wearable devices and small projects. – Multiple development interfaces: 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, ...
