This repo has multiple ways to run Servos from a keyboard. It is meant to be compatible with an Arduino Board and the firmata library. In order to successfully use any of the controllers in this repo, you first need to install the Arduino IDE. From there you have to locate how to install the firmata package and orient the correct port within that IDE that your Arduino is attached to. The last thing you need to do is load the StandardFirmata code inside the Arduino IDE and run it. Once that is all set and completed without error, it is time to dive into the Python side of things.
In terms of setup for Python, I recommend using a steady build of Python3 because that is what I used to develop and test. Next, you need to download keyboard and pyfirmata via pip. Search the web on further instructions on how to do so. Once that is done, you should be good to go to sample the code. I recommend using dynamicServoController because that one is more versatile and can be used for more use cases. Keep in mind these programs will only control Servo motors and will not control attachments such as LEDS or Stepper Motors.
The dynamicServoController is the script I recommend using regardless of what servos you will be controlling. It has the most freedom as of now. It will allow you to import a port that the Arduino is connected to. In addition, it will allow for custom servo inputs. You will be able to create a name, pin # on Arduino, lower bound and upper bound degree for the servo, keybinds for both adding degrees and subtracting from the servo, and a step size that the degrees will add to the current position at a time. The amount of servos in a system is not limited by the program, rather by the number of communication ports on the Arduino. I am currently working on a save feature that will allow you to save your setting that you have made for your particular case and use them again without calibrating the servos every time.
The staticSetServoController is the first project I made to test out operating a robotic arm that was 3-d printed. It only works with my specific build and is truly obsolete with any other type of build in this case. I recommend taking a peak at this code if you want to make a controller of your own because it is a lot more simple than the dynamic version. This version does not have any OOP in it. Instead, I made all of it to only work with one specific use. I would only recommend this code if you are going to modify it to work with just one Arduino Servo project you have in mind.
Send an Email to robbieg1515@gmail.com regarding any additional controller requests or to report the occurence of bugs while using. I am aware that better input checking needs to be polished in all of the code.
