The final article on making a Simple Tetris game using MicroPython and an esp32 microcontroller, as written in parts 1 and 2 of the first two articles, is described in the article below. Readers learn to design data structures, drawing the seven types of falling objects and controlling them to move left, right, and rotate. The second article has the object fall from above and keep the object’s position state. And in this article, the falling objects can be stacked along with moving left, right, and rotating the object will check for collisions with previous objects that have fallen before. Also, check if the object falls to the bottom if there are any rows without spaces. If any rows with no spaces are found, they will be deleted. And finally added a section to check the end of the game in case there is no place for objects to fall and move again as in Figure 1, ending our simple game making process.

From the previous chapter, we have drawn the background, random objects, object drawing, left and right moving and rotating. In Part 2 of the article, which is the preceding final chapter of the Tetris series, the topic is about creating a backdrop as a grid data structure. If an object falls to the bottom, it converts that object to a table of data as shown in Figure 1, and improves the way the object falls and controls/renders the new object by using a timer without checking for collisions from moving left / right, checking if the falling object overlaps the previous object, rotation and row cutting, which will be discussed in the last article or Simple Tetris Ep.3

This article introduces how to write a simple Tetris game by displaying it in a grid of 10 widths and a height of 16 as shown in Figure 1. Using esp32 microcontroller board connected to ST7735 display and 8 switches for controlling. Importantly it is written in Python via MicroPython compiled using the st7735_mpy library. In this article, we talk about storing 7 types of objects that fall, to support the display and rotation of objects with moving objects left and right. The controls and logic of the Tetris game will be discussed in the next article.
