picture box light

Hi,

I have been trying to solve this problem and create this program. However, I am having difficulty creating it as I am a beginner and have come here today, to this forum for your help.

My case study is this:
I have to create a picture for instance a balloon. Which I have done.
The form in C# needs to contain a password box for users to enter the correct password. If incorrect it should display a message. Which I have managed to get it done.

However, my problem is that I cannot get the balloon to light up. A repeating sequence of ON/OFF periods for the light is to be determined by a timer control.

The program can contain switch statements or if statements to construct to establish the correct state for the light and the correct timer interval as shown:

light = 0 light ON for 3 seconds
light = 1 and 3 light OFF for 1 second
light = 2 and 4 light ON for 1 second
light = 5 light OFF for 3 seconds

please help me re-write this code and I look forward to your response. Thank you
