Remember the video where Mr. Nicholas Duchette showed off his TR-595E Tricorder? His Tricorder screen is actually an actual LCD with animations. The whole display system uses an 18-bit 320×240 2.2 inch LCD screen, and powered from a Raspberry Pi Pico. The Pico was released in January of 2021 and it is their first board-based microconroller. The Pico also has 264kB or RAM, 2MB Flash memory and a lot of I/O pins!

This is another video from Arky’s Lab which shows the animated LCD screen. You can see the Pico in the foreground in some of the shots.
To control the LCD, it needs about 5 signal wires plus two more for power from the Pico.
Here is the video again, by Greatscott! who explains why the Pico is so amazing.

FIRST IMPRESSIONS

So, the Pico is in my hands and well, I think I need to start on learning how to program it. I’m going to study on the following notes which describes using an Arduino UNO to program the Pico:

And the important URL link for everything to work, I suppose.

And just tonight, my Pico has arrived.
Raspberry Pi pinout with so much I/O pins and you can replace all the 555/4017 circuits already.
So much Pins and they’re more than enough for the Tricorder’s sound and lights. If only I know more about Arduino programming but there is a Legal detail to this.
