NXT light sensor homework help Read value from NXT kit using light sensor and show it in the middle of NXT screen.
If measured lightness value is less than or equal to 50, right motor will stop and left motor will move with the power of 35.
If measured lightness value is greater than 50, left motor will stop and right motor will move with the power of 35. 


How can I do this?
Without solving your homework, you will need at least the following blocks:

for bullet 1


Light Sensor
Data to Text
LCD Panel Display


for bullets 2 and 3


Loop (forever)
Switch (based on light sensor readings)
Motor Block (4 of these, 2 for > 50% + 2 for &lt;= 50%)


And it probably makes sense to put bullet 1 inside the loop of bullets 2 and 3.
