Alternative boards and code

[vkumarsinghnoida]

Hi
My questions are regarding how to make the servo without custom pcb as given in coreless servo build.
How many boards are required to control 2 servos?
How exactly do we connect the board and use which software ?
And can we use the original potentiometer instead of the magnetic encoder ?

1. One "Adafruit ItsyBitsy M0 Express" board per servo
2. a) If you don't want custom PCBs and use a potentiometer you should follow the Schematics in ServoProject/PcbDesignes/MicroServo/MainPcb/MainPcb.sch
   b) The same software
3. Using a potentiometer is the default when creating a new configuration

1)How can I find the gear ratio of my servo motor as it is not given in the datasheet ? For the configuration program. 2)And which software do we need to boot the custom pcb and then do we just run the python code or we need Arduino ide too ? 3)And how can I control it after I have finished all the steps without your given gui ? Do I have to connect a usb cable or it needs pwm signal ?

1. best is to count the gear teeth to calculate it.
2. you program the board with the Arduino sketch.
3. please read "Communication bus setup for demo projects"

Thanks Unfortunately I couldn't find communication bus setup code. Can you tell me it's exact location (how to give the servo and angle)? And I have to install sublime text to run the bootloader and other code ? Like what are the steps from scratch.

You do not need to burn the bootloader if you use an off the shelf board, only when you have the custom PCB. I only use sublime text in the video to show text files and terminal output of the GUI.

Open one of the demos (there are Python, C++ and Arduino versions) to see how you control the servos.
