Good day,
Has anyone experienced an issue where the R4 Minima doesn't make a servo move, but when I use a board such as the R3 (CH340), this board operates the servo fine. Same connections, same coding, same library Servo.h. I am aware that the R4 Minima may not work with all the libraries that is compatible to the R3 boards.. (version 3 boards).
Is there possibly a specific servo library for the R4 Minima?
I'm still relatively new to micro controllers. Still learning.
Are you powering the servo from the Arduino ?
From https://docs.arduino.cc/tutorials/uno-r4-minima/cheat-sheet/
External devices with a high current draw (e.g. servo motors) should never be powered via the 5 V pin. It is mainly intended for devices drawing lower current such as sensor modules.
You missed a lot told in this link: How to get the best out of this forum - Using Arduino / Project Guidance - Arduino Forum

There was another topic about servo's not working correctly with Arduino Uno R4 earlier today:
Apparently there is a new version of the servo library that has not been published yet.
It is a small "micro" servo the same size as the blue ones found in Arduino kits, but I agree, the current is most probably not enough provided by the Arduino. Even though the Voltage is enough.
I'm sorry, I have to admit I was too quick to start a new topic, but I was extremely frustrated that the R4 doesn't move the servo.. not even with a powersupply. It has to be related to the library compatibility issues. I will have a look at the other topics I missed..
It's okey.
The R4 looks like being surpricingly different from the R3.
You've already got better tips then I can give. Stay well.
