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...

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 ...

Part 1 – Direct Current In the first part of our look at measuring voltage and current with microcontrollers, we will see how to measure DC voltage and current using an Arduino. In part two we will do the same thing with AC, but today our focus is on Direct Current. Introduction There...
An additional pin (next to the IOREF pin) is not being used at the moment, but enables new functionality to be implemented in the future without needing to change the pin layout again. Discussion If the power LED does not illuminate when the board is connected to your computer, the board...
