Checks if you have pressed the manual feed button, if so it feeds. Internet-Enabled Cat Feeder. I highly recommend you build a prototype with a regular arduino and a breadboard. This means if you turn it, whatever the program is busy doing , it registers your action. I've included the Fritzing file so you can load it up and see the breadboard layout in detail (cables are labelled in the program where nescessary). maybe the Ardunio board you are using does not have an 'A3' port. Once I was happy it would rotate without binding I fixed it in place with hot glue where it inserts into the pipe. DIY Simplest Automatic Pet Feeder With Arduino | Arduino | … Then I positioned the cursor on the hour digit of the clock, and told it to increase the hour as the encoder was turned (or decrease), then once the encoder was pressed, write the new "hour" to the real time clock, and then move the cursor to the minute, and start changing that, and so on. 1 x 1 1/2" PVC T-Piece pipe (ebay Â£2.89) http://www.ebay.co.uk/itm/121534086943?_trksid=p20... 1 x Arduino (I used an Uno but any type will do), OR ... for PCB (1 x ATMega328p, crystal, 2 caps, 5v voltage reg) - google "arduino breadboard".

Build this so you will never have to bust out the measuring cup or manually feed your dog again! Using the enable pin to power it down makes good sense - it doesn't need to hold the auger still when not in use! While you're away you can let your cats have the run of the place, but if you put out too much food at once hilarity may not ensue. I just copied your code, and used similar materials that you did, but when I run the program it just executes indefinitely every few seconds the feeding process, and I can't seem to find the problem. Displays the time, and the default feed times and quantity. Contribute to mgrenonville/arduino-cat-feeder development by creating an account on GitHub. Download files and build them with your 3D printer, laser cutter, or CNC. Saved by Mariano Maluf. Just search the web - there are loads of how-to's regarding changing regular servos to continuous servos. The auger is 10cm tall, the i3 prints up to 20cm tall. Simple as that. I built a breadboard with the LCD on first, then learnt the basics of how to control it. It's dead simple to knock up (google arduino breadboard) and is a good habit to get into - saves you a fortune on arduino uno's and means you can design one PCB to house everything. Finally I added the real time clock , the servos, and started programming the final code. 1st I learnt how to make the cursor flash on the screen, easy enough. FarmTek.com also might have some choices. Automatic Pet Feeder - Make: DIY Projects and Ideas for Makers are you using Ardunio Nano? Please if anyone can help I highly appreciate it. We are looking for someone to make 10 augers to fit into a 90mm T. The auger itself needs to be 60mm OD. Answer Thumbs up. Dogduino:The Automatic Dog Feeder using Arduino Posted By: arduino engineer on: May 03, 2015 In: Arduino Programmer Projects , Projects , Sound – Audio Project Ideas No Comments Print Email His physical design is good, but the code is too simplistic for my needs, there is no display, no multiple feedings, and no user variable portion sizes. I'm not sure why, and I've never been keen on the PWM method of controlling it's direction. For this step, you will cut the extra cardboard up, so the box will funnel toward the opening at the front. You can then screw this to the wooden box and it looks nice and neat! 1 x Bucket Dear dodgey, this is indeed a great home project! I've previous experience with Arduino, but have never used an LCD or a rotary encoder - but it's no problem - the Arduino tutorials and examples are amazingly well written. The box/base/enclosure is a simple MDF box (9mm). //It can be programmed for any time and any day #define servo1control OCR1A // servo1 is connected to Arduino pin9 #define servo2control OCR1B // servo2 is connected to Arduino pin10 //servo constants -- trim as needed Mine was a 6 wire - I idnetified which wires were the pair for coil "A" and which for coil "B" and ignored the remaining wires. See more ideas about food feeder, feeder, pet feeder. Are just plain lazy? I found printing it in one part no problem, Question Excellent project I'm almost done building this I just ran into an obstacle I can't seem to get past. For the encoder switch going to D4 you have what looks like either a 10K or a 220ohm resistor in series. Join the Revolution! Voila! I've included a screen grab of my arduino IDE for no real reason other than I didn't want this section to be without a picture :-). I am guessing from the circuit layout it's a 220 since there's a 220 in line with the manual switch going to A3. marshalroshan007. 2 years ago The food agitator is again 3D printed and screws directly to a servo horn. I screwed the servo to the auger base, making sure it was level and rotated without wobble, and then test-fitted it in a piece of 1 1/2 inch plastic T-piece tubing (commonly used for hot tub plumbing) - cost Â£2.90 off ebay (PVC solvent weld pipe - ponds / hot tubs etc). The code is not annoteded as well as I'd like as it was done in a hurry but the changes are obvious. Then cut two long pieces of wood and glue them on the side. There were a few key features that I needed that most other versions of dog feeders did not have. or verify you have correct board selected in complier, I have different issues with encoder push button. ThanksBut, could you please send back the .skp files in version 2014? Namely, a solution for power outage recovery feeding and addressing the issue of food getting stuck in the dispensing mechanism. This whole project is driven by an Arduino. Make one of the things in picture 2 with hardwood, make sure the servo fits in it.

They are either the type that rotate and unveil a meal, up to four times only, or the only half decent machine with a hopper is horrific to program, forgets everything if you remove the batteries, and frequently fails to even deliver any food! After I was happy with the arduino uno and breadboard test I replaced the Arduino uno with pure components - the ATMEGA328P chip, a few caps, 5v regulator (power supply) and a crystal - basically - an arduino without the circuit board.
