Hello everybody, I recently got started with my Elegoo Arduino Uno and I was using This Tutorial to learn some stuff about Arduino and how I can use it. Its official, so I followed all the instructions. Here is a picture of what I did:
The numbers on the bottom are going at an extremely fast pace, and whenever I turn the knob on the Potentiometer, It stops it for a second, saying that it is disconnected, then it resumes doing that with seemingly no change to the data.
I later realized that I had oriented the Potentiometer wrong, and the data IS indeed changing.
But now it's not changing predictably when I turn the knob -_- .
Is this supposed to happen?
Remove the potentiometer, connect one end of a wire to A0. You can connect the other end to GND (should give 0). You can also connect to 3.3V (should give around 675) and to 5V (should give 1023).
Note that cheap potentiometers not always hit the end.
If you wired the pot wrong, the wiper, when close to the 5V connection, will basically create a short on the 5V and therefore your board will switch off. The result will also be that you burn the carbon in the pot away and hence the damage mentioned.
You can not really live without a multimeter in electronics; it's one of the first things that needs to get on the list of things to buy.
Your topic is not indicating a problem with the IDE and hence has been moved to a more suitable location on the forum.
Do you have a multimeter to check it?
