Lesson 25 1 CHANNEL RELAY MODULE
Overview
In this experiment, we will learn how to use the1 channel relay module.
Relay is a kind of component when the change of the input variables (incentive) to
specified requirements, the output electric circuits of the charged amount occurs due to
the step change of a kind of electrical appliances. This company produces the relay
module can meet in 28 v to 240 v ac or dc power to control all kinds of other electric parts.
MCU can be used to achieve the goal of timing control switch. Can be applied to guard
against theft and alarm, toys, construction and other fields. Relay is an electrical control
device. It has a control system (also called input circuit) and control system (also called the
output circuit), the interaction between. Usually used in automatic control circuit, it is
actually with a small current to control large current operation of a kind of "automatics
