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 ...
先说输出模式。对于Arduino，用pinMode将IO口设为OUTPUT的时候，其实IO的状态为“强推挽”，也就是说设...

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. As expected, it operates at a reduced brightness due to the lower voltage. The ‘127’ is...
Output voltage proportional to AC or DC currents Factory-trimmed for accuracy Different Versions of ACS712 Current Sensor Note that there are three different versions of ACS712 Current Sensor for different current ranges such as 5A, 20A and 30A. Superficially, the ACS712 Modules for the different...

It's a switching DC supply so it's small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 9V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel jack, positive tip. This supply ...
