Traffic Light with user defined timeframes.

Joel Mack

I am trying to create a traffic light that collects user inputs to run the lights. I want to use graphics methods to draw the traffic light. The user will enter the number of seconds each light will stay lit. I have a start button to start the light and a stop button to stop the light. The lights will start one after the other and continue to run until the stop button is clicked. I have no clue at where I should begin.

OK I got a 34/50 on this project and am still uncertain on the timer functions. When the button is clicked it should run the the amount of time the user specified. This is the only trouble I think I have had. If I could see how to do this it would be great.

1: Drag three timers onto form and name them tRed,tYellow and tGreen
2: To set a timer interval - tRed.Interval = Convert.ToInt32(txtRed.Text);
3: To draw an ellipse use in the grbxTrafficLight_Paint event

Rectangle rctRed = new Rectangle (25,20,40,40);
e.Graphics.FillEllipse(Brushes.Red, rctRed);

4: Create three booleans redOn, greenOn, etc
5: When timer times out change boolean to true or false

See if you can work it out from here
