Jack50n Posted September 15, 2005 Report Share Posted September 15, 2005 Hi guys, I'm a college student involved in Electrical & Electronic Engineering. I wan to make an auto fish feeder for my project. I have an idea to build the auto fish feeder which using micro controller or timer. I need a complete circuit of thie auto fish feeder. Please help me on the circuit, because i have to hand in my proposal by next week. Thanks a lot dudes Quote Link to comment Share on other sites More sharing options...
ECET0purdue Posted September 15, 2005 Report Share Posted September 15, 2005 ok...ummm but can you do mine? Quote Link to comment Share on other sites More sharing options...
Jack50n Posted September 15, 2005 Author Report Share Posted September 15, 2005 I have try so hard to find on internet, but i couldnt find the circuit. Quote Link to comment Share on other sites More sharing options...
Staigen Posted September 15, 2005 Report Share Posted September 15, 2005 Hi JackI have try so hard to find on internet, but i couldnt find the circuitI did a simple search and it turned up 375,000 hits, i'm sure some of them included circuits, i didn't check! Why dont you design your own circuit, it would not be that hard? A microcontroller here, i belive, is not the way to go, it will make things moore expensive. Instead use a timer or two. On the other hand, a microcontroller would be moore versatile!//Staigen Quote Link to comment Share on other sites More sharing options...

Staigen Posted September 15, 2005 Report Share Posted September 15, 2005 Hi there again Jackif u have some site bout the circuitWich circuit, i haven't seen anyone yet? What is "thie auto fish feeder"(from the first post)? I thought it was a typo(thie).I proposed you to do your own design! I can help you with that, point you in the right direction and so on. :)//Staigen Quote Link to comment Share on other sites More sharing options...
Jack50n Posted September 15, 2005 Author Report Share Posted September 15, 2005 ok.. i've an idea. is about using a stepper motor to control the round feeder plate. The round feeder plate, there are 2 holes on it for the food drop from the container. hope u can get my idea. by using the micro controller to set the time and the stepper motor speed, every 6 hours the stepper motor will spin 180 degree, the food will drop from the 1 of the hole then close again. I really got no idea how to design a circuit to let it work. plz help Quote Link to comment Share on other sites More sharing options...
Staigen Posted September 15, 2005 Report Share Posted September 15, 2005 HiSo you have already made the feeding hardware, good! :)But, microcontrollers, i don't know much about them! :(Stepper motors? I only know a little about them! ???Tell me about the feeder hardware! Any pics?//Staigen Quote Link to comment Share on other sites More sharing options...
Jack50n Posted September 15, 2005 Author Report Share Posted September 15, 2005 i dunno which mirco shud i use... i just need a simple micro to control the time and the stepper motor speed. anyone help plz.. Quote Link to comment Share on other sites More sharing options...
ECET0purdue Posted September 20, 2005 Report Share Posted September 20, 2005 look into using a pic chip there pretty usefull for items like that... try a 16f84 you can get them free from ....some web site .... microchip.com maybe... i know they should have link it free items forum.cheersglen Quote Link to comment Share on other sites More sharing options...
MP Posted September 26, 2005 Report Share Posted September 26, 2005 Jack,Here is a link that will show you how to control a stepper with a micro. It also has the code, so you should be all set for this part of the design. http://www.avrprojects.net/But you are not telling much about the rest of it, so it is pretty hard to help further.MP Quote Link to comment Share on other sites More sharing options...
