robot arm servo- Carlos Sousa

I couldn't find my regular post so I am posting this
today at 3/4/19 I started a code which I will show possibly and hoepfull next class once it is finished. I ve been looking at many videos and trying codes that might work, most ofthe codes that I found did not work like I expected as they keep giving me a syntax error. I will also be working on this project at home with my own raspberry pi and work on codes. my main problem is the coding and where to plug in the servo cables to the raspberry pi. so far the theoretical code that work for one servo did not work for many.

ok so i found out an easier way, which is to find one code for one servo and replicate it 6 times since the robotic arm is 6 axis. I found a a code but I've been having trouble with the wiring. First i tried using a breadboard with a mod on it that had the layout of the raspberry pi on it but i couldn't figure out the wiring. Next open lab, I am going to try to plug in the wires of a servo to the raspberry pi itself rather than what i did. Here is the link of the code and tutorial i found: https://rpi.science.uoit.ca/lab/servo/
My next step after figuring out where the wires go to the raspberry i will then be replicating the code and do some research on how c++ and python can be read/translated for basic robotic programming. I'll also try doing the method with the breadboard again to make sure if i might have made a mistake the first time trying it.

Some time has passed and haven't been able to post since I've been busy catching up with this class's labs and work. Nevertheless, I found an instructables on robot arms and I've been reading through it to understand all the instructions before doing anything else. The link will be below this edited post of today. What my goal for this tutorial is to find a code to make this robot arm work and adjust it the way I want to. The instructable is based on this plus how to plug it in to the Raspberry Pi with of course going in and changing some of the settings before plugging anything in and running the module. I've done some research on some of the materials this person did it with and what stood out was the Flick Board which I never have heard of and when I researched it along with checking what need, I could not find what it is, although I will be looking more into it and start to follow along this instructable.
