Load the CustomCharacter example sketch in to your Arduino IDE and examine the code. As with the previous sketches we examined this one starts by loading the LiquidCrystal library and defining an object called lcd with the connection information for the display. It then moves on to define the ...
/** * 初始化显示控制器 */ void U8G2::initDisplay(void) 1. 2. 3. 4.注意点:这个方法不需要我们单独调用,会在begin函数主动调用一次,我们主要理解即可,会在里面针对具体的OLED进行配置;3.2.1.4 u8g2.clearDisplay() —— 清除屏幕内容函数说明:...

LED Matrix Displays are commonly used in digital advertising boards, event displays, and DIY projects that require visual output. They can also be found in a variety of consumer electronics, such as clocks, music players, and gaming devices. Below you can see a picture of a LED display. ...
Now you're going to need something to compile. Although we're working from the command-line, we're still working with the same language you would use in the Arduino IDE; so all the tutorials are applicable. Remember, however, that we don't have an LED connected to Pin 13, but 7, ...
3. The app doesn’t interact with the Arduino. If your Android app is connected to your bluetooth module, it should display the “Connected” message (as shown below). Otherwise, press the “Connect Bluetooth” to establish a bluetooth communication. ...
