We have designed a neumorphic companion web app for the device. Under Your Apps > SDK Setup and Configuration > Config (Sample given below).Then under the Database secrets tab, you can find the firebase auth key.The selected URL in the screenshot without " is the Firebase Host.Then move to Real-Time Database in Database.Then go and open your project (If you have no projects create one).In our project, we use Firebase real-time database to instantly post and retrieve data so that there is no time delay. Firebase is your server, your API, and your data store, all written so generically that you can modify it to suit most needs. Firebase frees developers to focus on crafting fantastic user experiences. Firebase Realtime Databaseįirebase is a mobile and web application development platform. Note: You can also hack your normal servo for continuous rotations by referring to this guide. If you are planning to make a large feeder consider huge torque generating servos. Here we used SG90 named servo which can produce optimum torque and that is very enough for this project. If you want to know more about this, just have a look here. ![]() If you need your device to only rotate for a specific period of time, then simply use a delay() statement to wait for a specific amount of time in milliseconds (1000 milliseconds = 1 second) before stopping the motor. Intermediate values can be used to change the speed of the rotation. A value of 1500 should cause the motor to stop rotating (and without any vibration). A value of 2000 should rotate the motor clockwise at full speed. A value of 1000 should rotate the motor counter-clockwise at full speed. While a regular servo motor only turns over a narrow range, with precise control over position, a continuous rotation servo has a shaft that spins continuously, with control over its speed and direction.Ī continuous rotation servo motor can be controlled by calling the servo.writeMicroseconds() function, which typically accepts values from 1000-2000. As you all know servo can provide high torque also.Ī continuous rotation servo (sometimes called a full rotation or 360°servo) looks like a regular hobby servo. The normal DC motor needs a driver circuit which will make the project a little messy. They can easily drive from the microcontroller itself, not needing an external power supply. In this project, we are using a continuous rotation servo for rotating the Archimedes screw, because they have integrated motor drivers in a compact and very inexpensive. So Wemos D1 Mini satisfies our need.įor programming up the Wemos D1 Mini with Arduino IDE, let's have a look here. We actually need a board with an optimum size that can be easily reprogrammable and powered from an external source. There is a wide variety of development boards with the ESP8266 chip. In addition, you can set your feeding schedule and change them easily using the scheduler in the companion app. ![]() You can instantly feed the fish using the "Feed Now" button.
