Fun With Snap Circuits 4: Let There Be Light!
“Some people believe that when you die there is a wonderful light. As bright as the sun but it doesn’t hurt to look into it. All the answers to all the questions you want to know are inside that light. And when you walk to it… you become a part of it forever.” —Poltergeist
So far we’ve taken a look at the Snap Circuits basic components such as the battery holder, switches, and wires (snap Conductors). We probably ought to try putting together a simple circuit, which will give us an opportunity to take a look at how each project is discussed in the Snap Circuits manuals. One of the first Snap Circuit projects (depending on the Snap Circuits set you have) is a simple circuit that will switch a lamp on and off. Here’s what the manual page looks like:
As you can see the projects in the manuals are self explanatory. Three electronic components, the battery holder, the slide switch, and a lamp are connected together with snap Conductors on the plastic base grid.
The next series of photos are a step by step build of the circuit:
When you are done connecting all the components you’ll notice that the labeling on the Snap Circuits blocks look almost exactly like the electronic schematic.
You can click on this link to see an animation of the current moving throught the circuit (place your mouse cursor and left click on the switch to turn the circuit on or off).
You can also build the lamp circuit online by clicking on this link. Here’s what the circuit might look like when you are done:
Unfortunately the Java applet has only a few components to use to build circuits, but is useful right now to help you understand current moving through a circuit.
