Click the sun. More sun = more power to the car! See inside to see how I coded this car using the brightness effect, a variable to store the brightness and influence the car, and make the car to move faster as the sun gets brighter.
You can check out the Scratch Team video tutorial series on Variables and Lists on the official Scratch YouTube channel (ScratchTeam) or see the video tutorial series for Conditional Statements, and find a link to written resources related to these topics in the video description. Thank you to Barefoot Computing in the UK for your workshop where I created this.
