№ 1. Table fan and tachometer from Spike Prime (eng)

In these practical works, you will need basic knowledge of Spike Prime programming (loops, working with subprograms, variables and etc.).

In the first practical work, we will assemble a tachometer. A tachometer (from the Greek tachos – “speed” and metron – “measure”, that is, a measure of speed) is a device for determining the speed of rotation of machine parts
and mechanisms.

In the first practical work, we will assemble an installation with an optical encoder to determine the propeller speed. Instead of a slotted plate, a propeller will be installed with two groups of Lego bricks – green and yellow.

Yellow color gives more than 90% light reflection, green color absorbs light from the color sensor well.

In the second practical work, we will assemble a table fan. You will need to write a program to display the motor power on the screen in two-character form (the standard way is to display text as a ticker).
