 Experiment 2: Control Relay In
the relay module, a PNP three tube 2N5401 is used to drive the 5V
relay. The relay touch point is routed out by the JP00 terminal.
When the relay does not act, the terminal is open. When the relay is
active, the terminal is closed. Leading the touch point out could
control external device, such as lanterns and so on. It should be
noted that control current should not exceed 1A, the voltage should
not exceed 120V. If using the touch point to control high voltage,
be careful!
Input 8way marquee program above.
 connect
P1.0 of P1 port(JP44) of the CPU to JP18 of relay part, you can hear
the sound of relay’s open/close. Wired the terminal out, you can
control the extern lanterns. The connect photo is like below:
