SCRATCH ACTIVITies
1 activity. With the same principles, build a barrier that goes up and down with a reducing mechanism when an object approaches and that it makes a sound while the barrier is lowering, to warn the needy.
I can not record it because it did nog give us time to record it.
If you want to see a example of this acticity, you can visit the weebly of my friend, Daniel.
2 activity. Assemble the mechanism that moves two levers simulating the mechanism of a car sewer, This mechanism will have two speeds that are operated with the tilt sensor (inclination 2 - slow speed / 4 speed fast inclination). When the bars are stopped they are in horizontal position.
I could not do the second acttivity because I did not have time to do it.
