![]() You can also spin a ball sprite in Scratch while the top is spinning. Just reset a timer when you turn the motor off and then when a space key is pressed set a variable (spin time) to the timer to show how long the top spun. You can also time how long the top spins. You can also use a variable to show the distance sensor value and set the value of the variable to the distance sensor value in a forever loop. The set contains 158 elements including a LEGO Hub, motor, tilt sensor and a motion sensor that add movement and intelligence to the model. Stále podporujeme tento hardware v offline verzi Scratch 2.0, která je dostupná zde. They will explore sky, sea and streets of present-day metropolis to discover the omni-presence of physics. Also, when the green flag (you can use a second green flag) is clicked loop forever and if (use a forever-if) the motion sensor value is greater than 50 turn off the motor since the top spinning device has been lifted off the top. Bohuel, nepodporujeme LEGO WeDo 1.0 ve Scratch 3.0, jeliko na mnoha nov podporovaných platformách nejsme schopni pipojit USB zaízení jako je originální WeDo. Upgraded with step-by-step Scratch programming instructions, this series is designed for students eager to learn about modern metropolitan technological solutions and are ready to start programming using text blocks. Top Spinner Build time: 30 minutes to 45 minutes Uses: motor and motion sensor When the green flag is clicked turn on the motor. The tilt sensor returns 0-4 with 0 meaning level, 1 meaning tilted down, 2 meaning tilted right, 3 meaning tilted up, and 4 meaning tilted to the left. The motor blocks could only be used with a LEGO WeDo Construction Set, but. They can be then found below within the Motion palette. To make the motor blocks visible, click 'Show Motor Blocks' in the Edit tab. You needed to choose them, as they were not visible by default. The distance sensor returns a value from 0 (close) to 100 (far). The motor blocks were in different categories in Scratch 1.4 and 2.0. The sensor blocks are in the Sensing category. ![]() The motor has power levels from 0 to 100. The motor blocks (tiles) are in the Motion category. ![]() 1 Activities for LEGO WeDo in Scratch 1.4+ Barb Ericson Overview You can use Scratch 1.4 with the LEGO WeDo tilt and distance sensors and motor.
