Button to change velocity

[Connor-91917B]

Hi. I am trying to make a button that changes the velocity. I want 2 fixed velocities, so it will make life a lot easier for me to code it, but I still have No idea how to. I am using vexcode pro. Thank you!

You will need to have a variable to store the desired velocity.

Then use an if statement testing for button press to change that variable.

Set motor speed to the previously mentioned variable.

Gotcha. I will try to get that working today.

You will need to have a variable to store the desired velocity.

and you will need a latch to change from one state to another.

Button toggle code makes rest of bot not work

You should only have one while(true). That code will never exit so it gets locked into the inner while. Use If statements instead. To take advantage of the latch toggle it needs to be declared outside (above) of the conveyor_control() function. Every time you call conveyor_control() it creates a new instance of the buttonLast and toggle so it doesn’t remember the previous state. Edit: Added sample code bool toggle = false; bool buttonLast = false; void conveyor_control() { //If button i…

Button pressed, switch to tank drive won't work

So recently I decided to make a slow mode and a control switch button on my controller but when I press the button nothing happens, also, I want it to run once on press not like 8 times because it is pressing. I do get test on the robot when the button is pressed but the rest won’t work. Let me know if you can help! else if(Controller1.ButtonRight.pressing()){ Brain.Screen.print("Test"); if(Controller1RightArrowDriveSwitchArcade == true){ drivetrainLeftSideSpeed = Controller…

If I remember right, there is a solution to your problem there. You will need to do a little bit of looking, but the same general problem was solved here.

My team achieved this with an if else statement alone. we are updating it now.

When you press the button does the programming continuously jump back and forth between the two values ? Or how did you overcome this issue that other teams have had in the past?

We had the button held down to switch the speed and experimented with pressing to switch the speed.
