This was the hardest step for me since I was new to coding with C++, so I modeled my code after viorelracoviteanu's Useless Box tutorial on the Arduino Project Hub. After trying to understand what the code was actually doing, I began creating mine.

A useless machine that flips down a switch. Turns itself off, with 15 different movement effects.

The Angry Octopus is a pet octopus that hates getting triggered . When one of its switches is flipped on, its arms are quick to switch it back off. This project was a great way to learn more about circuits and servos and was a fun challenge. A useless machine or useless box is a device whose only function is to turn itself off.

Dec 11, 2019 · The code sets the idle position of the boxservo to 70 and of the handservo to 180. That means, that with a continuous rotation servo both servos would spin in idle state, the handservo being way faster than the boxservo.

The code for the useless box is very simple. First of all you must include the servo library, then create two servo objects (one for the door and one for the finger) and attach them to Arduino's pins in the void setup function.

Nov 25, 2019 · Useless Box Project: In this Digi-DIY I will be covering the creation of my Useless box. Our previous box was no longer working and I decided that it needed an update from its ATMEGA328P-PU chip to an Arduino Nano for additional program-ability and ease of use.

A useless machine that flips down a switch. Turns itself off, with 15 different movement effects. Find this and other hardware projects on Hackster.io.

Jul 12, 2020 · The code for the useless box is very simple. First, include the servo library. Then create two servo instances (one for the door and one for the finger) and attach them to Arduino's pins 9 and 10.

In this project, I use Arduino Uno as my controller, and you also need some other parts as BOM table showing below. Feel free to replace some of them if you are familiar with arduino projects.
