Current Connector

Aim

Current Connector introduces the concept of logic gates in the form of a simple circuit game. The following four gates are introduced: AND, OR, NOT, and XOR. This game gives players a basic understanding into problem solving using logical thinking skills. It utilises concepts directly from the ELECTENG101 first year engineering course.

Objective

A number of batteries are connected in a circuit on the playing field. The player objective is to complete the circuit by connecting appropriate logic gates into their correct positions. Once connected, the circuit will be complete and current will flow allowing the light bulb to illuminate.

Logic Gates

Four basic logic gates are introduced in this game.

AND Gate

The output of an AND gate is only light if there are two light inputs as shown in the truth table below:

Input A	Input B	Output
0	0	0
0	1	0
1	0	0
1	1	1

OR Gate

The output of an OR gate is only light if there is at least one light input as shown in the truth table below:

Input A	Input B	Output
0	0	0
0	1	1
1	0	1
1	1	1

NOT Gate

The output of a NOT gate is only light if the input is not light as shown in the truth table below:

Input	Output
0	1
1	0

XOR Gate

The output of an XOR (exclusive-or) gate is only light if the inputs to this gate are different as shown in the truth table below:

Input A	Input B	Output
0	0	0
0	1	1
1	0	1
1	1	0
