Max voltage received by the Alvik motors?
The Alvik uses motors with an operating voltage of 6V.
However, on pg 10 of the Alvik datasheet (https://docs.arduino.cc/resources/datasheets/AKX00066-datasheet.pdf), it looks like the motors only receive a max 5V of power during operation.
Am I reading this correctly? I'm trying to understand how much voltage these motors are receive as I am using them in a similar project....
I hope this qualifies here - docs.arduino.cc page error - dead link
I noticed broken link(s) on the docs.arduino.cc Serial pages.
The link points to
.../Serial, but the acurate link is to .../serial/
One page with known broken link: https://docs.arduino.cc/language-reference/en/functions/communication/serial/available/

Make your own Uno no longer detected
My Uno R3 is no longer detected when I plug it into the computer, so I need to reset the MEGA16U2 chip.
However all the instructions involve the reset jumper pins, but this board does not have those, instead having a USB C to Serial module, see attached photo. How can I reset the chip??...
Build your Uno R3 no longer detected
I have an official build your own uno R3 with USB-C and an ATMEGA16U2, but now it is not being detected when I plug it in to both my Mac and my pc. This board doesn’t have the reset jumpers next to the usb chip, it does have jumpers at the other side and I tried resetting using that but no joy.
How do I set this board to be reprogrammed with dfu programmer or flip?...
synth shield audio in
I went ahead and added a guitar plug into the audio input on my solder your own arduino kit with synth shield
I can hear the crackle of the guitar being plugged in, but I don’t hear any other sound from it, other than the existing synth sounds the kit had me program in.
Do I need to adapt the code in order to amplify the signal to the speaker or something similar? Has anyone done this with their synth shield who’s could help? Many thanks!...
How many UART ports does the Arduino UNO R4 have?
I saw in a website (given below) saying that the Arduino has two UART ports, one in the USB and one in 0 and 1 pins. But in the Arduino website, it shows only one.
https://dronebotworkshop.com/arduino-uno-r4-minima-wifi/
Also if it does have two UART ports, is it only in one of the variants or both the variants (Minima and WiFi) have them?...
