View Arduino Nano Digital Pins Not Working
Pictures. I was work on a project and every thing was good i don't know what is the problem with this and what is you can set those pins to high and then check with voltmeter if they are showing a voltage of approx. There is nothing wrong with my code or circuit because it works.
Lab Digital Input And Output With An Arduino Itp Physical Computing from itp.nyu.edu
I bought an arduino nano clone a couple of months ago on ebay. When i plug it in, the nano lights up and works and everything, the problem i am having with it is that every so often i plug it in, the digital pins don't get powered. But the a6 a7 pins do not pull the relay.
The question is how can we get the digital pins on the arduino nano to fire using an external power source and input from a windows pc?
As mentioned earlier, arduino nano has 14 digital i/o pins that can be used either as digital input or output. I'm checking the relay with esp and arduino nano. You would configure the digital pin to generate the pwm (pulse width modulation) it just a combination of the bit (1 and 0) for a particular time set to create a frequency. Pi to the nano with a 20k resisitor worked fine.
