- This video will describe a real world application for microcontroller interrupts. A rain intensity sensor to shut off an irrigation system during heavy rainfalls will be described.

If there was a RUclips award for " Most concise" you'd win everytime. Love the Forth stuff! Cheers!
Thanks Paul! Appreciate your feedback.
Indeed!
Clear, to the point, no frills, no waste of time.
That rain gauge is such a neat device. Thank you for showing us how it works. And, the debounce circuit makes the code so much simpler, I'm sure.
You're welcome! Glad you liked it.
Thank you for execellent video! I enjoyed seeing and learning something new. Please keep videos coming!
More to come!
Great interrupt tutorial, bookends eh!
Another way to do this is to use the hardware counter to do the counting. Interrupt when it reaches a value set up in the timer. Not really critical in a slow system but for a faster requirement like a shaft encoder or stepper motor a hardware timer would be preferred.
Great tip! That is another way to do it. Back in the day before microcontrollers I was building these using the CD4060 as a gated timer and a CD4017 as a counter.
Great ingenuity !
Awesome. This was really interesting!
Thank you!
That is a very specific amount of water it drops per bucket... As the designer one might have hoped they aimed for an easier to recall number ;)
It was probably originally designed to measure the rainfall in inches ( .01" ) and the conversion to mm gave us that number. The more expensive gauges have adjustable stops for calibration.
@@0033mer I did think that but could not resist ;) Eh you could just shove some known mass in both anyway :D A small model of Archimedes maybe ;)
Love the mix between in the lab and in the field :)
What are the benefits to use RJ-11 cable?
How many blueberries does a typical plant produce ?
RJ-11 is your typical telephone interface with quick dis-connect and faceplate jacks available at any hardware store. Blueberry yield depends on the size of the bush. We did a heavy prune this spring so the yield will be down but the berries will be bigger. On the average you can expect 8 to 10 lbs of berries per bush.
Another great video, thanks Ken. A very good explanation of interrupts. And I was fascinated by the rain gauge sensor -- I haven't seen one of those before. Just curious, what's the operating voltage and current of the solenoids you use? I've got a 4-channel solenoid board prototyped, it's 12V and 1A. It's designed to daisy-chain over I2C, and with multiple boards you can control up to 28 sensors. Wondering if this would be of any use to you?
Hi John .. the control solenoids are 24 VAC. The Hunter irrigation controller has a rain detection input terminal strip that just needs a relay contact for activation. The one they use is a piece of felt that expands when it gets wet and opens a contact. When it dries out the contact closes. The bucket rain gauge sensor is a lot more flexible.
👍
Hi.Can you made more video about Lora Ebyte E22 or E32 series to control relays?
@@abpccpba I asked for help and I have seen that he is working with this modules.I did my homework and research.What is wrong with you?
@@keeper1855 OK
The code would be similar to the RC car using Bluetooth video:

Do you have a pair of E32 modules?
@@0033mer Yes I have two esp32 dev boards. Thanks for reply and for video link.
Are your blueberries an interruptor the main topic of the video? 🤣 see what I did here?
Good observation.
Forth? Just… why?
Why not?
Because it's incredibly efficient, lean code, and a lot of fun. It's also the faster the debugging environment you will ever use. Get yourself a scamp3 and see for yourself!
The animals chew on the pipes because of the liquid fertilizer. Liquid Poop and Pee. Programming in MS notepad is real oldscool
The coyote problem started before we had fertilizer injection and all lines were cleared out with compressed air. Conservation officers have seen this a lot especially when the young pups are teething and they like the soft plastic which is just the right diameter for chewing. I have recently been using Sublime Text for programming but all files I distribute are in Notepad, so whatever the computer or platform users have I know they can view a simple ASCII test file.
very crytic
