problem with potenciometers and diy simrig

what should i do about this? a0 should be gas, a1 should be brake and a2 should be clutch, but only the a0 is working i guess and it somehow changes the value of all 3 analog ports

Servo Motor Not Working Correctly

Hi, after connecting the servo motor to VCC (5V), GND and a digital pin, I tried running an example on Arduino but it does not provide a continuous rotation. In the video you will see that it rotates a bit and then stops. I then reset it and it spins a bit and stops again. Since the power is cut off during the reset, it makes a small turn again and does not continue. I would like to clarify a bit: I know it is 180 degrees, there is no problem in the code, the default example provided by Arduino and the pins are connected correctly....

Need help in making a faraday cage protect against 2.4/5G Hz wifi.

I am trying to make a faraday cage that shields against wifi but it is not working the slightest. The cage is made of stainless steel mesh with 4-4.5mm hole size. The bottom has aluminium foil to ensure continuity and I also grounded the cage but somehow it just does not work. Any suggestions please I am desperate

Bidirectional I/O buffer

For something I am making I am going to have each I/O pin of a microcontroller controlling the gate of a transistor or MOSFET. But I also want to use those I/O pins as inputs while only connecting devices to the drain or source of each transistor. Is there a type of transistor that would allow current to flow back through the body to the gate? Or would I need some extra components to do that reliably.

Cant Connect to Arduino Nano V3

I remember I had to do something funny to my home computer to get it to connect to my Arduino Nano V3 and that Arduino IDE would fail to upload code or Upload, but it would just keep doing the default blink code rather than the code I was uploading. I have a surface that I got so I can now code and tinker between breaks at work but Im having the same problem and I can't remember what I had to do to get it to connect and upload successfully. Its a fresh install of Windows...

Custom motor driver module

I am planning to make a high current motor driver module with IRLZ34NPBF mosfets. But I am wondering what components to add to make a nicely working system, like resistors, capacitors, and diodes. I know I need a 10k resistor for the gate to ground, and I know I need diodes from the drain to the vcc. But is there anything else I should have other than those?

Problem connecting Arduino to Laptop

Everytime when I plug my elegoo into my laptop it makes the connecting sound and then a second later it makes the disconnecting sound and it wont pick up the port the elegoo is plugged into in the IDE. I have tried multiple different ports, cords, and even a different laptop but they have all ended with the same problem. I am using an elegoo uno r3. Below is the exact tinkercad I am using. https://www.tinkercad.com/things/0Qo4PFFvZtA-daring-rottis-esboo/editel Help would be greatly appreciated a...
