The Arduino blink LED circuit is a simple circuit that works great for starting to learn Arduino. Both the code and the connections are straightforward so that you can understand it with little to no background. In this quickstart guide, you’ll learn how to connect an LED to an Arduino b...
这些正电荷由电池或其他电源产生,穿过导体,然后流入电子组件(如LED)。“电流”表示在金属中流动的正电荷量。如果有大量正电荷流过,则LED等电子部件就能够获取大量的电能(能量),光照强度更大。相反,如果电流较小,那么供给的正电荷就较少,在使用LED时,光照强度将会更弱。 电流的单位是“A”(安培)。 除此之外,带...
voidsetup(){ pinMode(LED_BUILTIN, OUTPUT);// 初始化LED内置管脚作为输出}// 下方为循环函数,代码写入里面voidloop(){ digitalWrite(LED_BUILTIN, LOW);// LED管脚给低电平,LED亮(低电平有效)delay(1000);// 延时1sdigitalWrite(LED_BUILTIN, HIGH);// LED管脚给高电平,LED灭delay(2000);// 再延时2s...
Serial.print("\nYour Morse code Translation : "); endPos1 = morseCode.indexOf('#'); while(endPos1 < morseCode.length()) { extractLetters(morseCode.substring(startPos1, endPos1));// This function would extract Letter as name suggest and would convert code to text SIMPLE! startPos1 = e...

I’m looking to do some master to multiple slaves to multipule slaves. I know they can not talk all at once which is fine but I really need to figure this out. any site I can look at for advanced bluetooth code? Reply Martyn
