Voice and Touchscreen GUI Relay Activation - How To Use A PiRelay V2 HAT with Raspberry Pi

The PiRelay V2 HAT is a solder-less solution to drive 4 Relays (30 Volts DC at 10 Amps) from a Raspberry Pi Single Board Computer. I'll even show you how to control the Relays through Spoken Custom Keywords and Utilise a Touchscreen GUI Control.

All relays on the PiRelay V2 HAT are electro-mechanical relays and you can quickly identify them as the four large through hole black box components on the top of the PCB board. These are electro-mechanical as inside they have physically moving contacts on the output circuit which are controlled directly by a Raspberry Pi Board through I2C communication. This means you can stack these Hats for even more Relay control! These HATs are designed to keep your Raspberry Pi Safe. Also, keep in mind there is a 2 Relay HAT Version that fits cleanly onto a Raspberry Pi Zero and Raspberry Pi Zero 2.

Now for me, the customisable voice control is really cool. I can now properly recreate the "Open Sesame" moment from the Classic Arabian Nights story of Ali Baba and the Forty Thieves. The one missing puzzle piece I need is simply a mouth of a cave in which forty thieves have hidden their treasures. The magic side of things has been sorted 😊
