There are two different ways to program your robot’s speaker mouth. Let’s get started!
Use the Solution sheet to complete the following steps:
I can set sensor events to control my robot
I can program my robot to make a sound
I can program my robot to emit high and low frequencies
I experimented with high and low frequencies
I changed the note, octave, intonation, duration, and pause of the sound block
I programmed the robot to make a sound when the microphone reads a loud noise
Can students program more than one sound?
Can students figure out how to program “say some sounds”? Hint: you need an array!
Can students program a script to turn off the frequency?
