  • Nice tutorial. It could be improved a bit though. The other commenters have given very reasonable suggestions as to how to do this (e.g. a bit more info on the voltage drop across the LED in the animated switch as well as @bokubob's comment about the confusing image). Also, it seems there's another small mistake with the AND-gate: "If either transistor is turned off, then the output at the second transistor’s collector will be pulled low." The output of the 2nd transistor is the emitter, as it is an NPN-transistor.

No public wish lists :(
