Hi guys, Got a question; I want to operate a machine. I want to turn a bunch of different relays on and off in different orders, so I they need to be programmable. For this project I'll be using a rpi and a touchscreen, got the touchscreen working with the pi, and for now I've been using a lighttpd ...

Hi Guys, I'm working on a system with a RPI and relays. Yesterday finally my 16ch 5v relay arrived. Because of the amount of relays, I connected it to an external power supply. I connected the 5v to the vcc (jd-vcc) and the ground to the ground of my rpi and the ground of my external power supply. O...

You should really look at solid state relays for switching line voltages. The advantages over mechanical relays are: - UL/CE approved - directly drivable from the Rpi +3 volt GPIO pins. No interfacing. -silent in operation - zero crossing switching - opto isolated Thanks Richard, But I read somethi...

@PeterO Thanks Peter, Actually I'm controlling some 0.05A devices, but the relay board I found are 10A max relays. Othen than that, i'll be using 2 devices that can use like 12A. That's why I use the 30A certified relays, just to make sure I dont fry anything. So in the end I'll be using like 13A at...

Hi guys, I want to connect quite a lot to the RPI. I want to connect 11 x 10A relays, 2 x 30A relays, 2 float switches and a temp sensor. I have a few questions about this. Since I use a lot of GPIO connections, I thought the RPI B+ is the way to go, is this correct? I've ordered an Optocoupler rela...

Thx!
But how, there's Just 17 gpoi ports.
Will it work if I connect the sensors and a few relays to the gpoi ports, and the rest of the relays with the USB cable, to a USB relay?

Can that work?

Hi, Im fairly new to the rpi. For automation I want to connect a few water sensors, a water- temperature sensor, and 13 relays to it. It is quite a hard probably, but I want to make it work. So my question is, is it possible to connect al that to 1 pi? And of so, how Do i Do it? I've found a few rel...

Hi guys, Lately I've been busy on a new project. I want to be able to open and close a few relays and read the temperature. In oder to do so, I figured, I could use a RPI. But I want to be able to control the opening and closing of the relays and reading of the temperature by using a tablet. What I ...
