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 😊

The touch screen is freaking nice for truck lighting

@Core-Electronics Месяц назад

Every project can be made better with a touch screen, and what a great application for it as well!

@stevegrimeszz Месяц назад

@@Core-Electronics can we add more relays and a gui that matches???? I have no idea how to do that.

@thesystemsucks Год назад

great stuff.. great video. clearly delivered content and concise. have been ordering from you guys for years but didn't know you had youtube 👍

@Core-Electronics Год назад

Thank you for your kind words VIP 😊

Thanks for this tutorial! It was exactly what I needed to get started.

Great to hear!

Great video and info. I am a noob and need to control 8 relays with 8 physical push buttons and i want a GUI for it also... I think I have figured out the code for the relays and buttons.... with this GUI script I think I can adapt it to fit my needs... (I am not using raspberry relays since I already have cheap relays...) Edit: I ended up getting advised to use chatgpt. it took me about 40 minutes to have it write the code for me and even adapt the GUI code from core electronics to fit my needs. Litterally as easy as asking someone else to do it for me.... First time I ever used chatgpt for anything! LOLOL p.s. As an electrician the double stack raspberry has one HUGE flaw; When the screen is mounted you cannot acces the screw terminals for the relays... So if you need to swich a wire to another terminal you will have to disassemble the screen first...

What a good video. I might actually try it

@Core-Electronics Год назад

Get amongst it! 😊

neat... I want a relay switch hat now.

I'm subscribed and all notifications are turned ON. Yet I have not got the notification for your last video 3 days ago in my subscription posts. I had noticed the videos when I went to your channel home page. Please check if there is any issue there. May be it is a glitch or may be I'm the only one having the issue. I don't know. Anyways putting it out there so that you may have a look at the issue.

I'm new to the pi but I'm building a gaming table and I need the pi to run 2 actuators simultaneously and have 3 different preset heights and manual control and on the same setup run a bunch of leds with a bunch of presets all from that touchscreen panel. Any advice on hardware/software ill need?

I can see expanding this to send mqtt messages for home assistant to turn on various devices.

Love it 😊

@jorisdenengenieur1239 Год назад

Great video! Is it possible to modify your code: button1 pressed and relay 1 retracted? Release button1 and the relay stops working? Where can I find this solution or can you explain us how to create the necessary code? Keep up the good work. Greetings from Belgium

@Core-Electronics Год назад

Absolutely mate, all this open source scripts means you can alter them to do anything that you desire 😊! Come hit us up at the forum and we'll best be able to guide you in the right direction - forum.core-electronics.com.au/latest Also dive into our Python Workshop, if you knock that out of the park you will have all the skills needed to solve your project - core-electronics.com.au/courses/python-workshop/

@user-pj9th1jt7c 9 месяцев назад

Is it possible to stack a motoron hat on top of the PiRelay hat or will the GPIO usage conflict?

@jonathanboot 9 месяцев назад

Hi Tim , is it possible to given a example for POLOLU controller (Pirelay) _GUI for 2 DC motors buttons for on /off en speed control , please thanks luc Belgium

@ezequielvalentin-crespo8779 11 месяцев назад

Can the UI be altered? Changing the button Style and add a wallpaper?

@robertraman6307 Год назад

Would the relay work with a 220 V 2000 W heater fan running in 15 min intervals checking if the temp ha reached a certain value and then stops and restarts when the temp is dropped a few degrees?

@Core-Electronics Год назад

Heyya mate, these relays top out at 30 Volts DC at 10 Amps. If you want to control some seriously powerful current and voltages take a look at the SparkFun Qwiic Quad Solid State Relay Kit - core-electronics.com.au/catalog/product/view/sku/KIT-16833 That relay kit is capable of shuffling around 40 Amps at 28-380 Volts AC!

@yakubumshelia1668 6 месяцев назад

This screen seems to consume a lot of gpio pins. It could be a problem for my next project. Is there any recommendations

@jhulindawati7489 Год назад

hello, I can't speak English. I'm using google translate. I'd like to ask. I get the message "RPi.GPIO as GPIO no module" what is the solution? I have installed but it didn't work. Please help me 🙏🙏🙏

@Core-Electronics Год назад

All good mate, type this into your terminal | sudo apt-get install python3-dev python3-rpi.gpio | . Then type | sudo thonny | into your terminal and open the script in this special Thonny IDE Version that has administrator powers. It should all work after that 😊

@darkplayer4371 Год назад

please make a video on a product like if we want to make a box in which we place the product to sale the user select the 1 product by a screen or buttons then he/she enter money in the specific place of that product or machine so then he/she got the product out of the cabin or box I hope you understand what I am trying to deliver

@Core-Electronics Год назад

In that case the Vending Machine DIY Project you need to see is this - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BHQBsswUeT0.html
