is the focus locked onto some other component?
have you added event handlers to the buttons?
if so what happens when you click the button - nothing?
putting a console output in event handlers is useful for debugging, e.g.

private void motorONbutton_Click(object sender, EventArgs e)
        {
        Console.WriteLine("motor on button clicked"); 
        motorON = 1;
        motorButton = true;
        motorPWM = false;
        }

you can always remove it later

hi horace,
Right now I have used Application.DoEvents(); But its process is very slow.
Actually, I don't know much about event handlers do guide me more about it.
Do you know about background working in C#?

Thanks,

if you do a web search on C# GUI event handling it will give you plenty of links, e.g.
https://msdn.microsoft.com/en-us/library/aa983763(v=vs.71).aspx

I often use a background worker (in effect another thread of control) to carry out time consuming tasks - add it to the Form, create a DoWork event and start it in the Form constructor, e.g.

        public Form1()
        {
            InitializeComponent();
            serialPort1.Open();
            backgroundWorker1.RunWorkerAsync();
        }

again plenty of example are on the web, e.g.
