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...

This board comes with built-in LED connected to digital pin 13. HIGH value at this pin will turn the LED on and LOW value will turn it off. This gives you the change of nursing your programming skills in real time. AREF模拟输入口参考电压 AREF stands for Analog Reference Voltage which is...
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 a number that can range from 0 to 255, with 255 being the brightest setting. You can use this to set the...
When using the breadvolt, or any battery power supply on a breadboard project, do not turn the power supply on while the Raspberry Pi Pico is connected to USB, as you could generate voltage conflicts. It is an either or. If the USB is connected, the power supply should be OFF. Or if...

but also allows for simplification of the testing process. For instance, an Arduino-powered wattmeter can be adjusted to observe the data on the Serial monitor and create a graph on the Serial plotter, or include an SD card to record the voltage, current, and power values at set time inter...
configurations). Shields designed for the new layout should work on any board that uses the new pin locations. 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 ...
This was a much-needed change, and it allows the Leonardo to work with shields that would have interfered with the B type USB connector on the older models. The Uno R3 and the Leonardo both use the same PCB pin layout, but some of the microcontroller functions are different. In the ...
