Tutorial: Controlling a Sprite's Movement w/Arduino Uno, ADXL335 GY-61 Accelerometer & mBlock 5

The video tutorial demonstrates how to use an Arduino Uno R3 with an ADXL335 accelerometer to control a sprite in M Block 5, a variant of Scratch 3.0. The tutorial covers setting up the hardware and software, using upload mode to interface the Arduino with the sprite, and calibrating the accelerometer for accurate movement. The demonstration shows how tilting the accelerometer moves the sprite on the screen, with adjustments made for sensitivity. The tutorial concludes with a practical demonstration of the setup.

What are the three axes of the ADXL335 accelerometer used in this tutorial?

• A, B, and C

• X, Y, and Z

• L, M, and N

• 1, 2, and 3

Which software is used to move a sprite with the accelerometer in this tutorial?

• Scratch 2.0

• M Block 5

• Arduino IDE

• Python

What is the first step in connecting the Arduino board to M Block 5?

• Change the sprite to a cat

• Download additional software

• Connect the board to the USB port

• Install a new operating system

What is the purpose of the 'Upload mode broadcast' extension in M Block 5?

• To interface and communicate the board with the sprite

• To save the project locally

• To change the sprite's appearance

• To increase the speed of the Arduino

Why is it necessary to calibrate the accelerometer in this setup?

• To ensure the sprite starts at the correct position

• To save battery life

• To change the color of the sprite

• To increase the speed of the Arduino

What happens if the accelerometer is not calibrated correctly?

• The project will not save

• The Arduino will not power on

• The sprite will change color

• The sprite will not appear on the screen

How is the sensitivity of the sprite's movement adjusted in this tutorial?

• By changing the sprite's color

• By tripling the X coordinate value

• By using a different accelerometer

• By reducing the Y coordinate value
