Build an Automatic Pet Feeder. An easy DIY project that also beginners can pull of, this is not your regular craft. We don’t want the servo turning around, so we have to make something to hold it in place. Circuit Wizard - Cat Feeder component side.pdf, Circuit Wizard - Cat Feeder solder side.pdf. The hardware is kind of academic - it's all in the code. America has some good machines but they start at $300 USD, and shipping would be painful to the UK, so I decided to make one! 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. 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). 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. My feed servo started to refuse to go backwards recently. Then I added a rotary encoder and learnt how to use that, then I combined the two in code. All seemed a bit like guess work, so, I replaced it with a Nema 17 style stepper motor, driven by an Easydriver stepper driver. Tired of having to get up early so your dog doesn’t attack you for his food? Also you canÂ leave a comment or rate or subscribe! Extra cardboard Powered by arduino, using a 3D printed auger, and programmable with two feeding times with a user set quantity of food, with a battery backed up internal clock.My cats drive me nuts in the morning begging for food so… Previous Episode: https://www.youtube.com/watch?v=ZaRss2xjFAoHi!

Was surprisingly easy. 1 x Standard 3 pin servo (This is the one I am using) Automatic Pet Feeder - Make: DIY Projects and Ideas for Makers 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. The "Dir" pin goes to analogue pin A0 on your arduino (although we are using this as a digital pin). Simple as that. I've made an Instructable on it - have a look under my name - it works every time (the PCB, not my name). For more detail: Dogduino:The Automatic Dog Feeder using Arduino, Your email address will not be published. Use a Nema 17 size stepper of your choice. The code is not as intimidating as it first looks, and I've tried to annotate it as much as possible. to mount the LCD so istead I 3D printed a home designed facia - this takes the LCD, push button (for manual feed) and the rotary encoder knob. The food agitator is again 3D printed and screws directly to a servo horn. I first made a box, then cut out the base with a jigsaw, the holes for the auger with a hole cutting saw you attach to your drill, and the square holes for the control panel and servo with a jigsaw again. The dog will eat the Arduino first, anyway. Voila! I'm not sure why, and I've never been keen on the PWM method of controlling it's direction. 3 //Automatic Dog Feeder. 30 New Diy Automatic Dog Feeder Concept is free HD wallpaper. We are looking for someone to make 10 augers to fit into a 90mm T. The auger itself needs to be 60mm OD. Excellent project I'm almost done building this I just ran into an obstacle I can't seem to get past. Just search the web - there are loads of how-to's regarding changing regular servos to continuous servos. 1 x Push button (This will be a override button) Checks if you have pressed the manual feed button, if so it feeds. Reply You don't need to go that far - you can run your feeder with a regular Arduino, and a breadboard, or you could use that PCB board where you cut links with a knife - the choice is yours. 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. Has anyone else come across this and have a fix? I built a breadboard with the LCD on first, then learnt the basics of how to control it. This instructable is part of the Sparkfun and Epilog challenge so if you like it, vote for it. 1 x Soldering Iron resistor, .... Man, this is a great project. I've attached the PDFs for printing. did you make any changes? 162. This is where the Arduino comes in and saves the day. You may want an extra CD in case you make an error, This step is kind of self explanatory, All you need to do is glue the servo head to the inner rim of the cut CD, Make the circuit from the schematic in the second picture. You can tell slic3r to print support material for only the 1st "x" rows, but I didn't think to do that. I didn't want the hassle of trying to cut neat enough holes (square holes!) The second servo is a regular servo, used to agitate the pet food before each feed, to stop it clumping (the pet food is known as kibbles to the USofA I believe :-) ). Question Motor "B" pins go to the motor B pair of wired of your stepper. Hi, have you fixed the 'tmElements_t' was not declared in this scope problem? Good day! With four wire steppers you won't need to worry about this!. 1 x 3D printed Auger parts (see auger step) (pennies if you have a 3D printer). //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 I highly recommend you build a prototype with a regular arduino and a breadboard. ThanksBut, could you please send back the .skp files in version 2014? I built a Prusa i3 for around Â£350. Please if anyone can help I highly appreciate it.

I'm a newbie, trying to repeat the same construction at home to feed my guinea-pig =). 1 x Sharpie Marker 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! I've used the accellstepper library to drive the stepper, and I've used the enable pin on the Easydriver to power down the motor coils when not in use, or it gets really warm being held in place for hours upon end. Checks to see if the rotary encoder has been pressed if it has: it then goes into the programming routine, cycling in order through clock, portion size, feed time 1, feed time 2. Finally I added the real time clock , the servos, and started programming the final code. This means if you turn it, whatever the program is busy doing , it registers your action. Dear dodgey, this is indeed a great home project! For the encoder switch going to D4 you have what looks like either a 10K or a 220ohm resistor in series. I had to trim the base with a knife a bit where the recess for the servo horn is, as it has collapsed a fraction due to the lack of support material. You will notice I said "servos".
