Digital circuit

A digital circuit is a type of circuit that uses electricity to make a machine do a certain task. Digital circuits have different parts that make up the circuit. Different parts of a digital circuit work together to do the task. For example, some parts allow electricity to pass through while other parts don’t. Other parts direct the electricity in different directions so it can do the right task. When all the parts are connected together, it makes the digital circuit that can do the task.
