Re: How to wire a Raspberry Pi to a Sainsmart 5v Relay Board

Hi guys, I am attempting a sprinkler controller as well, using the Sainsmart SSR board which looks as though all the protection is included - I just connect my GPIO straight to the channel input (attachment) and a 5VDC supply to power the relay Just wondering if anyone has written their program in P...

Re: Programs for payment

Cheers guys, I really appreciate the help Hardware wise - it's cheap! and it's an introduction to the Pi I eventually want to build an underwater camera (ROV) so playing around with the GPIO's and learning programming hopefully will get me there. I think I might do a course on programming before I g...

Re: Programs for payment

you mean if I write the while true it will just keep repeating?
do you know if the program would continue if the pi was to power down and restart (power failure)?

Thanks for that

Re: Programs for payment

Thanks for the input guys I have an 8 Solid state relay board to control the four solenoids and the pump (either directly or with a heavier duty relay as it may draw a bit on startup) that I got off ebay I was thinking of basic programming (Commodore 64 days - loong time ago) but firstly after doing...

Programs for payment

So i am resorting to paying someone to write a program or binning the lot. I want an irrigation contoller (2 actually...

Re: Preloaded SD Cards

Sirius thanks for your reply, i just got really excited when i stumbled across the Pi on the net but the more I read the more confused i got.
Now at least I have a direction to head in, to get python onto an SD card and start learning how to speak snake
Cheers

Re: Preloaded SD Cards

As a complete beginner I am really lost as to what to do. I want to do 3 things with the Pi 1. Irrigation controller - 4 relays for 24V AC. 1 relay for 240V AC. The 240 has to be on the same time as any of the other relays. The 4 relays run 10mins each then all relays off for 20 or 40 mins. And repe...
