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

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.

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.

*–question1——*answer1*– -Wire 1–battery —-Light bulb—-Wire 2
–Question 2—–ans2——–
-Question 3——ans3———

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)
