You have the controller, you have the diode. The controller has a number of pins (holes). Where should you put the diode so that it starts blinking?
The small holes on the controller are called pins. On our controller we have 32 pins. The more pins that you have, the more elements you can controller with this microcontroller. For this video the interesting pins and 13 and GND
Let's move with the VEX EDR robot using its motors, the wheels and some RobotC programming. We devide the program in three parts - Connect the motors, program the controller and turning.
Conenct the motors of the VEX EDR motor to the VEX Corted Controller. For connecting we need the motor drivers.
We are ready to build the first program for moving the robot forward and backward. We learn how to build simple programs for moving the program. But it is not that easy...downloading to the robot does not always result in the robot moving.
Now that we know how to make the robot move forward let's see we can make it move backward.
In this episode we combine in a single program the previous two programs for moving forward and backward.
With this video tutorial, we start with Turns with the VEX EDR robot.
Spinning with the VEX EDR robot involves the use of both motors. The left and the right. Every robot with wheels could spin and this makes not exceptions.
The next important step when turning with a robot is to learn how to do an Arc turn.
Where is the math while turning? Is there any math involved? Should there be?
To prepare the robot to move in a square and to use a loop in the program we would first make this VEX EDR robot move forward and turn, using a program developed with RobotC.
We start with the previous program where we made the robot move forward and turn. We continue in this tutorial with repeating the same RobotC instructions four times. Our goal is to make the robot move in a square.
The previous tutorial showed you how to copy/paste instructions in RobotC. The current video will introduce you to loops.
In this tutorial, we set the task of implementing another figure with the robot - a triangle.
The more advanced task is to more in a polygon. This would require calculating the degree of each of the turns and RobotC is a language in which you could implement this math calculation very easily.
