How to measure output
Posted: Fri Aug 18, 2017 11:24 pmHello all,
First post here, first project with a NodeMCU. I am trying to control a digital led strip with the NodeMCU v2 and using ESPlorer, when I send the command to turn on the lights it shows the NodeMCU receiving the command and setting the lights to r:255 g:255 b:255 so they should turn on all white but nothing happens.
I've measured and at the end of the strip I have 5V (same input voltage) so that isn't a problem. The program is supposed to output to pin D5, is there a way to measure the current or voltage on pin D5 when the command is sent to see if the pin is actually outputting anything?
Thanks!
