is there a kit to make outside timer

hi I struggling

id like to either use a Arduino or a raspberry pi with say 7 relay and have real time so its up to date… is there a kit or help me get a kit from sparkfun

I been struggling on the Arduino website I cant understand the coding some of it and to figure the math to do days/hours difference from one to another

I wanna make an outside timer… to turn on 7 different relays at different times some same time etc… to water my garden… as the store bought ones are junk… and I wanna be able to adjust the times or see what ones are on or off from a laptop or a cell phone… I know I asking a lot but wanted to know if you guys help write the code or if there is a kit already to do 1 or 2 timers that are the same like the digital outdoor timers you buy at a store

like 24 entries… but I wannna do say 24 entries x 7 relays so each realay gets 24 enteries… am I asking too much … is it possible… I just stressed over code… and since I in hospital dealing with kemo I get tired I was hoping a simple setup build I frustrated… so I not sure which way to go Arduino or raspberry pi

I just wanted a better version and be able to see it when I not home

and I not sure if I posted in the right forum… to ask

Hi Comet.

We don’t have a kit for this unfortunately and we can’t help you write the code needed to make a timer, but other forum users might be able to assist you with code.

Raspberry Pi might be easier than Arduino for building a multi channel timer since the Pi already has a clock built in. If you were to use Arduino, you’d need to connect a real time clock and then write code to check what time the clock has in addition to the code needed to operate your relays.

For relays, I’d go with something like two of our [Qwiic Quad Relays connected to the Pi via I2C. That cuts down on the number of wires you’d need to control the relays to just 4 wires.

The part you’d need to figure out is writing a bit of code to check the time and see if a relay needs to be on or off at that time. If you check the time and one or more relays need to be on, a few simple commands via I2C will turn on whatever relays need to be on. The Arduino code in the [hookup guide for the Qwiic Quad Relay might be helpful in giving to some pointers on what you need to create on the Pi.](https://learn.sparkfun.com/tutorials/qwiic-quad-relay-hookup-guide)](https://www.sparkfun.com/products/15102)
