Is there such an electronic chip system to serve as a correct/incorrect notification device?

Question

Such as if I made a learning tool for children, pressing a button while, for instance, a picture of an apple is matched to the word "Apple", a green light turns on. If the picture was matched to say, the word "Dog", a red light turns on.

But it has to be in the form of an electronic chipset. The lights need not be the said green/red.

It would be nice if you know the proper name of the set and possibly a weblink.

If you can't find it, providing a possible alternative will also get you best answer.

Answer 1

This is so simple it does not need any electronic circuits.

You only need a battery, a light bulb, and a few wires.

You create a board with answers on the top, questions on the bottom. Under the board you connect the answer with the question with a wire. Next to each answer/question you put a little spring that connects to the wires under the board.

You have two master wires . One from the light bulb, to select an answer, and one from the battery to select a question.

If the kid picks the correct answer, the circuit "closes" and the light is on. If not, there is no light.
Of course, on the board, the answers and the questions are in "random" order.

Check any book on simple electronic projects and they have it. You may even still find such games in the market (They were popular in the 60's)

Answer 2

for most undemanding digital gadgets there is not any undeniable data on both aspect. Even in what's considered a secure device there is not any assure a glitch would produce a random signal with damaging consequences. So quite than inspect each and every decision and, to err on the aspect of caution, that is given a blanket judgment, 'no longer Allowed'. at the same time as i grow to be an 141 FE in flight calculations were made both from charts and tables in the to regularly through a slide rule. at the same time as pocket calculators got here out we concept we had an a lot less complicated technique. besides the undeniable fact that the Air stress disagreed and calculators were prohibited on the Flight Deck. the in trouble-free terms pocket calculator we were allowed grow to be the little 6" slide rule made through a jap organization. (solar, i imagine.) I'ld like t have one immediately as a collectable yet my youngsters discovered more beneficial advantageous makes use of for them.

Answer 3

I don't think that application is common enough to require a chip to be manufactured that serves that purpose. You need a fairly simple circuit to provide the functionality you desire. Maybe program an 8051 microcontroller or PIC microcontroller. A chipset won't do all of it either, you need a way to deliver data to the chip. How will the chip know you're right or wrong? You need a set of logic variables etc. to program into your micro.

Answer 4

Yes. There is such a system.
