This KBA provides a minimal code example with Arduino Uno board for the TLI493D-W2BW 3D magnetic sensor with the in silicon A0 address. The I2C address would be 0x6A for write or 0x6B for read. In the 7-bit format, the I2C address translates to 0x35. Code ...

I2C总线 1、I2C:一种串行总线,飞利浦公司推出,由数据线和时钟线组成,空闲2根线都是高电平,可以挂多个接收器,通过总线仲裁来获取总线控制权。 2、I2C总线数据传送 (1)数据传送时,时钟信号为高电平期间,数据线上的数据必须保持稳定,只有时钟线的信号为低电平期间,数据上的高电平或者低电平状态才允许变化。 (2)...

Fig. 1 shows the test setup for this series, in this case an Arduino Nano. I'll assume one can program their Arduino board. The Nano and most Arduino boards today have an LED on digital pin 13 (DP13). The use of the I2C LCD display is optional but makes understanding the process ...
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter

Hooking up the Arduino The hookup for our Arduino Uno is pretty simple. You’ll need the following: Arduino Uno or clone LED, any color will do Resistor, 220 ohms or any value from 150 to 470 ohms Potentiometer, 5K or greater, linear taper preferred SSD1306 OLED Display with I2C interfa...
