I want to use Servo motor with Arduino Nano 33 IOT.
However, Arduino Nano 33 iot is 3.3V so it did not work.
I tried to convert Servo motor from 5V to 3.3V with using Arduino UNO.
But it did not work at all.
In this case, How can I use servo motor with Arduino Nano 33 iot
Please, Please Please help me...!!!
you need to join the ground pins of the two arduinos.
Better still, you can use the 5v out pin (and ground) from the Nano instead of the UNO for the power for the servo. (then you wont need to join grounds)
If you are going to put a load on the servo then you should supply power from a source other than this pin.
Again, you would need to join the ground pin of the Arduino and the ground of the power source.
P.S. This post really belongs under the "General Electronics" forum rather than this one.

Have you tried powering the servo from the 5V pin of the Nano 33 IOT after shorting the two pads that enable the 5V from the USB input to be available at the pin? This may not work if the servo input will not work with a 3V3 input but it is worth a try
