6 pin hke relay Projects for children to a maker classroom

[pintomarcelo]

I need a simple project with code to make using HK 6 pin relay. Something that can be teaching about Arduino, by using digitalWrite high/low to activate/!activate relay, printing states on monitor serial...
It's for a diy maker classroom

You'll kill your Arduino if you don't know how to properly connect a relay to a controller.

Using a relay module will reduce risks considerably.

Hi, @pintomarcelo
This link may help, it uses a relay module that has the needed driving circuitry to allow a microcontroller to activate a relay.
