2、输入(INPUT)模式 3、输入上拉(INPUT_PULLUP)模式 (仅支持Arduino 1.0.1以后版本) 在输入上拉(INPUT_PULLUP)模式中,Arduino将开启引脚的内部上拉电阻,实现上拉输入功能。一旦将引脚设置为输入(INPUT)模式,Arduino内部上拉电阻将被禁用。 设置Arduino引脚为输出(OUTPUT)模式 当引脚设置为输出(OUTPUT)模式时,引脚...
37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...

The following Arduino PWM code sample reduces the voltage and average current output of pin 11:void setup() { pinMode(11, OUTPUT); analogWrite(11, 127); //Operates at a reduced voltage and current. } I connected a small LED to pin 11 to see the results of the above PWM code sample...

Instead of struggling with two multimeters, you can just use the handy INA219 chip on this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision. Works with any and all Feathers! Communicates over I2C so its super-simple to use, you can even ...
When a sufficient voltage is applied to the gate the MOSFET is switched on. This allows current to flow between the Drain and the Source. The MOSFET acts like a very low value resistor when it is switched on. Since MOSFETs have a very low on resistance they don’t dissipate very much ...

Serial.print("Current:"); Serial.println(cur); } The main function of the code is to read 1000 times (with a delay of 1 msec) the voltage from the analog input A0, average this value and then converting it into a current. Constants and Variables ...
