Protect the joints with electrical tape or heat shrink.Solder the other 3 to the Vcc cable of the power supply.Solder 4 of these cables to the GND cable of the power supply.Locate the Vcc (usually the red wire) and GND wires (usually the black wire).Strip back a portion of the outer cable.Cut the end off the cable with wire cutters.Tun on the soldering iron to the correct temperature for your solder.To power the boards you need a 5V voltage source. We use a soldering iron to create the power cables. The motor order is x-motor, y-motor, z-motor from top to bottom of this diagram. You should wire these up to and Arduino Nano using jumper cables as shown in the diagram below: A little electrical tape - Heat shrink would be betterĮach of your motors should have come with a driver board.This will allow you to drive the 28BYJ-48 stepper motors used for the microscope. This guide tells you how to create your own motor controller that is compatible with the Sangaboard firmware. The official project uses the Sangaboard motor controller, but this is currently difficult to get hold of. We’ll be happy to help.Building a Sangaboard-compatible motor controller If you cannot manage to control your stepper using this tutorial, do not hesitate to leave a comment or to contact us. Steppers may have different characteristics. #define IN1 11 #define IN2 10 #define IN3 9 #define IN4 8 int Steps = 0 int Direction = 0 int number_steps = 512 //= 2048/4 void setup ( ) The stepper 28BYJ-48 describe a rotation in 2048 steps. To control a unipolar motor we used a 8-step sequence. As the sequence to move one step at a time is known, the position of the rotor can be kept in memory and thus control precisely the motor without sensor. Steppers have several phases which if energized with the correct sequence of impulsions can rotate in discrete steps. There are also stepper motor drivers for more advanced features and performance such as the A4988 or the TMCs often used in CNCs. To simplify your life, there are Shields integrating these ICs and allowing to drive several motors (Motor Shield V1 and Motor Shield V2). In this tutorial, we study the use of integrated circuits for stepper motor control. To give motion to a robot, electrical motors are used such as stepper motors especially when precision is required with an open-loop control. One of the main objectives in robotics is to make things move on their own.
