Adding Screen Elements to Timer
Introduction
We will now start porting over the timer elements to the Little Python Brain. We will start by showing the timer seconds themselves on the screen.
Components Needed
- Little Python Brain
- A tablet/phone/laptop
1
Adding screen elements
Simply initialize control of the screen by dragging both of these blocks to the top of the blocks.
2
Clearing the screen and printing the time
As with previous projects, we need the oled.fill(0) to clear out the screen and the oled.show() blocks to write the information that we specify using the oled.text() block.
As for the oled.text() block, simply type “Time: ” followed by a plus sign and a string conversion of the variable second.

Time's Up!
Finally, we do the same thing with the “Time’s Up!” indicator after the main loop.
The Complete Code
Run the code! Next up, we’ll learn how to make a self-contained timer app using just the touchpad and the screen. No need to manually type in the timer seconds!
