Thanks for who shared the information above and we will update more about our final year project next week. To change the time intervals simply is by changes/turning R-Var and for the pellet quantity is by changing C-Var size. So the total time intervals would be T = 3 minutes x 10 x 10 = 300 minutes = 5 hours. Time interval if the IC 555 keeps following the formula:įor short, if we set the timer T = 3 minutes, the both counters will multiply the time to be 10 x 10 = 100 times.

The resistor functions to unload the capacitor so that the capacitor is then ready to be loaded for the next cycle. From here we could figure out that the bigger the capacity the longer the relay connects which then causes the motor works to expel pellets centrifugally. After the capacitor is about to be fully loaded, the relay shuts off. (Remember: a relay owns its own resistance) which consequently trigger the relay for some time to turn on mechanics section. The output pin from the last counter is then fed to the capacitor and-relay in series. The circuit is using regular timer (IC 555) sending pulse to 2 cascaded counters of CMOS 4017. This are some of examples of the working system that we found : Other than that, relay and capacitor also required in this circuit, same as the resistor to operate as decrease the value of current enter to the component or go through the circuit. So we know that the function of the timer give pulses to the microcontroller and then go to the motor to operate it. Here are the description about the timer : We also doing research about the timer that we are using in this circuit. So here we can build up the automatic fish feeder circuit. These are some example of an automatic fish feeder without using LOGO soft :

We have been searching for weeks to gain some of the information on how to design an automatic fish feeder. 1-48 of 296 results for 'automatic fish feeders for aquariums' RESULTS Amazon's Choice FREESEA Aquarium Automatic Fish Feeder: Vacation Timer Feeder for Fish Tank Electric Adjustable Auto Fish Food Dispenser 0. Thus, process of this circuit will be complete by using program ,timer and microcontroller. In addtion, we still have to use timer and microcontroller to give pulses to the motor through out the relay. The program is the main objective in this project because the program will be set, what time should be give to the circuit to feed the fish. Although ,we have been supervise by Sir Halim to search and create a circuit that can be program by the LOGO soft. My partner and I are being ask to create a fish feeder that can be set the time to feed the fish. This project is to design a prototype of automatic fish feeder by using logo soft program.
