Fish Feeder With Shakin´Slider

thingiverse

I loved the "Automatic Fish Feeder" by pefozzy (thing:2539750). I used an old 40 x 20 servo that I had retrieved from an old rc-car. Pefozzys base for the big servo has no room left to mount the arduino nano. I could have glued it on top, but I wanted to add a button as well. So I imported the stl into Freecad and drew this remixed design. ### Mods - added space to mount the arduino (upright) - added space for a 6 x 6 push-button - changed the arduino-sketch: added a parameter „shots“ to increase the amount of food dispensed added a shaking to the code to make it more reliable - the shake helps lightweight flakes to slip down added an interrupt for the button to manually give food or for testing reasons added a flashing off the onboard-LED, so there is an additional optical feedback I add the original arm and tank as well - so that the thing is complete here. If you want to use a servo of a different size, a bigger tank or the original sketch, than have a look at the source and the other remixes as well. ### Using it When using it you should mount the downside at least a few centimeters above the water level and well ventilated. Otherwise water will condense and the food may stick. Maybe later I will add a slip or equivalent and mount the feeder even higher (idea: thing:2798949) https://youtu.be/ObHfq6WmjdA The sketch runs a counter from startup and dispenses food every 24 hours. You can feed manually by pushing the button. Changing „shots“ in the sketch will influence the amount of food dispensed. UPDATE: Bug in *.ino - new sketch 20.10.2020
