Arduino Engineering kit Rev2 without Simulink/Matlab

Hi, before I start this endevour, and trying to face the wall a billion times. Is it even possible to complete this project without using matlab or simulink? My current interests are learning C/C++, and Python, through this kit.. If possible. Therefore, if I were to use vscode and PlatformIO, again, would this be possible? I am specifically looking into programming the webcam controlled rover.

Tiny machine learning kit shield problem

Hi everyone, we have a small issue we need help with. We're using the Arduino Tiny Machine Learning Kit and trying to power the Arduino (which is on the shield) through the Vin pin of the shield. We're supplying 3.3V to the Vin pin, coming from a step-down converter that regulates 12V down to 3.3V. Unfortunately, the Arduino doesn't seem to power up — there's no LED activity or any sign of life. We've connected GND from the power supply to the GND pin of the shield. (Arduino nano 33 BLE Sense lite)...

Arduino connects and works with IDE but doesnt appear in device manager and doesnt connect to excel.

Arduino connects and works with IDE but doesnt appear in device manager and doesnt connect to excel which is what i want to use it for. I want to use data streamer but it doesnt connect or read any data. I tried most things that the internet said but nothing is working. I am using a giga r1 on windows 10.

Uno R3 not detected

i have a "Make your own Uno kit", 100% official Uno R3 with a USB-C module, however it is no longer detected at all in Device manager. The power light is on etc. I have looked up and as far as I can see, it is the usb module that needs reset and reloaded in order to get the device detected by device manager again? However, I don't know how to do that with this, normal R3's have the reset jumpers but this doesnt...

Arduino Alvik motor deadband values?

For the Arduino Alvik, I see that the wheel speeds can be set to a given RPM using the following alvik.set_wheels_speed(speed, speed) If I set the speed to a very low RPM value like 1 RPM, would the bot actually turn the wheels at this rate and move forward? I ask because I'm developing a similar bot with n20 motors, and am realizing there is a deadband where the motors will not turn at all if they are given sufficient power over a certain theshold, so setting the motor to a slow RPM will result in it not turning at all. ...

Help understanding the code flow within the Alvik libraries

I'm attempting to learn more about the Arduino Alvik codebase. Specifically, I'm trying to trace the code that executes when calling a drive() command, all the way to where the individual motors speeds are updated to make the bot drive. My current understanding is that:...

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....

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?...
