#KNIGHT RIDER THEME SONG ON ARDUINO HOW TO#

The above will create an infinite loop that runs inside tkinter's mainloop. # do something, such as turn an led on or off The basic pattern is to write a function that does some work, and then have that function cause itself to be called again using after. It's very easy to set up a persistent repeating task in tkinter, if the task doesn't take more than a couple hundred milliseconds (if it takes much longer, your UI will start to lag). You don't need threads for such a simple task. Logo = PhotoImage(file='/home/pi/Red LED.gif') Logo2 = PhotoImage(file='/home/pi/Off LED.gif') () # I added this line to make the exit button work Self.button9 = Button(frame, text='Exit', command=self.close_window) Self.LED0 = Label(frame, image=logo2) #added to create a row of images Self.button0 = Button(frame, text='Knight Rider OFF', command=nvert0) Label(frame, text='Turn LED OFF').grid(row=0, column=1) Label(frame, text='Turn LED ON').grid(row=0, column=0) Self.master=master # I added this line to make the exit button work Self.signal = False #added to stop thread I think there must be a way to do it in the same way that the digital write is incremented to create the streaming LED on the piface expansion board.

I've tried a few things in the while loop but can't quite see how to achieve it without a lot of lines of code. I'm trying to add some code to make the row of LED images stream an LED image in the 'on' state left to right along the row of images, like the Knight Rider car's front lights.

In one part of the code I open a new window which shows a button and a row of images of a LED in the 'off' state. Using Tkinter I've created a Gui with buttons to operate the pi-face LED's. I'm learning python with the raspberry pi and a pi-face expansion board.
