LEGO Wedo motor power block and distance sensor experiment

Let's do 2 experiment today, one to show how motor speed changes as input to motor power (speed) block changes. Click or scroll down to view:

Another, experiment repeat the above but this time using a distance sensor as input to the motor power block. The programs for the 2 experiment screenshot below:

Explanation of the programs

Experiment 1: The program sequence: Start block > Motor power block > motor turn this way block > repeat loop block
(input to the motor power block via number input)

On clicking start, the number input to the motor power block, motor turns, loop back to start, check input again, motor turns, loop back .......

Experiment 2: number input replaced by distance sensor input. As hand move closer, distance sensor input changes from zero, increasing till maximumm 10

  1. May i ask why is the value of the distance sensor value increase with the decrease of distance? Thought it was the other way round.
