3 Ways to Use Acceleration in an Arduino Sketch

This tutorial explores using acceleration in Arduino sketches to enhance LED animations. It covers setting up an Arduino circuit, understanding the base sketch, and implementing three types of acceleration: linear, exponential, and using the square root function. The tutorial aims to make animations more lifelike by varying LED blink rates.

What is the primary purpose of using acceleration in Arduino sketches as discussed in the tutorial?

• To add color to the Arduino board

• To make LED lights blink at a constant rate

• To reduce power consumption

• To create more lifelike animations and movements

Which component is NOT required for setting up the Arduino circuit in this tutorial?

• Arduino Uno board

• Breadboard

• 220 ohm resistors

• LCD display

What is the purpose of the array in the Arduino sketch?

• To control the power supply

• To specify pin numbers for LEDs

• To store delay times

• To manage serial communication

How does linear acceleration affect the LED blinking pattern?

• LEDs blink faster and then slower

• LEDs blink at a constant speed

• LEDs blink randomly

• LEDs blink slower and then faster

What is the initial value of the timer variable for linear acceleration?

• 500 milliseconds

• 1000 milliseconds

• 2000 milliseconds

• 1500 milliseconds

What mathematical function is used to implement exponential acceleration in the sketch?

• Logarithmic function

• Power function

• Sine function

• Square root function

In exponential acceleration, what happens to the delay time as the loop iterates?

• It decreases linearly

• It decreases exponentially

• It remains constant

• It increases exponentially

What is the effect of using the square root function on the timer variable?

• It increases the delay time

• It decreases the delay time rapidly

• It keeps the delay time constant

• It reverses the LED sequence

Which type of acceleration results in a gradual increase in delay time?

• Square root acceleration

• Exponential acceleration

• Linear acceleration

• Random acceleration

What is the purpose of resetting the timer variable in the sketch?

• To synchronize with external devices

• To prevent the Arduino from overheating

• To ensure consistent acceleration patterns

• To maintain a constant LED brightness
