I would like to use an arduino uno r3 board that i have for a robot project and want to use ARC to drive servos and such. How would i do this?

In ARC, you can use the servo Control skill to control your servos. You can also use other skills and controls to program your robot, such as the Movement Panel, Scripting, and Auto Position.
If you need more specific help with your project, please provide more details about what you are trying to accomplish and what components you are using.

But I can answer this. You can use an ESP32 or ESP8266 as a UART to WIFI bridge. Everything that comes over the wifi TCP socket would be forwarded to the UART for the Arduino connection - and vice versa in reverse. There are many open-source projects for making the ESP32 or ESP8266 in wifi uart bridge mode.
Once you get a wifi uart bridge on your device, configure it to listen on port 23, which is what ARC uses by default. Then, you can connect the UART from the ESP to the Arduino Tx0 and Rx0 pins. Put the regular EZB firmware on the arduino and voila
Waiting for ezb client..."
Make sure you have installed the appropriate ezb firmware on the uno as well
This tutorial all worked well with the exception that i cannot for the life of me get this uno to connect to arc. Baud rates are set. Boxes are checked. Even shows on the board some activity quickly but something is not quite right here. I followed this tutorial to the tee
It connects and disconnects because the ESP32 RELAY firmware is a relay. It acts as a passthrough to the connected arduino. The ESP32 relay firmware on its own will not do anything with a connection from ARC. The relay will forward and receive all data from the wifi to the RX and TX ports of the ESP32
So you'll need the Arduino UNO firmware on the Arduino. Then connect the arduino's TX0 to the ESP32's RX0. And then connect the arduino's RX0 to the esp32's TX0
Once the ESP32 and Arduino are connected, you can use ARC to connect to the ESP32 relay.
My internet isn't turned on yet so I have to use my phone. In your photo, it looks like the RX and TX lines are connected incorrectly. It looks as if you have TX0 of the Arduino connected to TX0 of the ESP32.
Connect the arduino's TX0 to the ESP32's RX0. And then connect the arduino's RX0 to the esp32's TX0
Also, check the esp32 firmware to make sure the baudrate matches the arduino, which is 57600. That’s something I’m unsure what value is set on the esp32
Again, ARC is notconnecting to anything. It is attempting to make a connection through the ESP32. The ESP32 is unable to relay data to the Arduino. Therefore, ARC disconnects because it does not receive any data. The ESP32 is not dropping the connection. ARC is dropping the connection because no data is coming through the ESP32 from the Arduino. I wrote more detail about this in a previous response you want to scroll up and reread. Lots to type on a phone screen haha
ensuring the tx and rx are connected correctly is also mandatory. If you’re unsure of the pinouts, find a reliable source to check. The tx must be connected to rx. The rx must be connected to tx. I sound like a broken record but it’s absolutely imperative
lastly, you cannot power the Arduino off usb with the connection to the esp32. If you power it off usb, you will be using the built in serial for debugging and not ARC connection through the esp32
