Testing our Parking lot barrier:

This Parking lot barrier has a mechanism that moves the barrier up and down.
We can use a worm and worm-wheel mechanism, gear system mechanism, or pulley system mechanism.
The project has one electric motor with forward and reverse control to control the movement of the barrier.
We will use a double circuit switch to control the electric motor and limit switches to know if the barrier is up or down.Then we will change the double circuit switch by a relay.

Later we will use two LED (Light Emitting Diode) one red and one green to make a Traffic light.
Finally, we will use the Scratch / Picaxe software to program a PICAXE microcontroller that will be the brain of our project.
