Q: What will this project teach students?
A: This project is designed to teach students how to use the design process as well as identify what information will be relevant to their project.
Q: Why did you choose to incorporate an Arduino over a Raspberry Pi?
A: An Arduino is simple and fairly easy for inexperienced students to learn how to use the board. Raspberry Pis require a lot of installment no matter how you want it to function. Since our board only needs to run a motor, an Arduino makes much more sense.
Q: How do I know if I'm using the right fish food
A: The food you use will be dependent upon the fish you choose and the mechanism you use to open the fish food. foods vary by weight and size, so if you use flakes, make sure that they are small enough to fit through your hole opening. If you use pellets, be sure that they are not to heavy for your container to hold. Overall, the food you choose matters but only in obvious ways.
Q: My transistor keeps blowing out. How do I keep that from happening?
A: The transistor blows out when you apply power to the motor and the motor doesn't spin. If you are follow the procedure in step 3 and your transistor is continually blowing out, try lightening the load that your motor is spinning.
Q:Why is the duty cycle end at 255?
A:In binary, an 8-bit piece of data has 256(2^8) different possible arrangements, but they are counted from 0, not 1, thus 0-255 is all of the possibilities in an 8-bit system.
