Once you’ve built the racecar, grab a ruler or measuring tape before moving onto the next activity.
Start Your Engines…
Put something in front of the car like a can or a box, so that the sensor shows a reading less than 10 (look at the bottom right corner of the programming screen).
Program the car so it stays in place until you remove the object.
Another Start
Instead of an object in front of the car, write a program so it stays (hint: the hourglass block), and then starts when it hears a loud noise (microphone block).
