The Useless Machine was not created by me, it can be found in Make Magazine and in numerous Instructables and DIY articles online. A useless machine, sometimes known as a "useless box", is a device which has a function but no direct purpose.It may be intended to make a philosophical point, as an amusing engineering "hack", or as an intellectual joke.Devices which have no function or which malfunction are not considered to be "useless machines". The Arduino is always ON, this is why I added a switch for the battery to save some power when the machine is not in use. Reply. I built mine, maybe not perfect, but still much personal :) 1.

Arduino Most Useless Machine Ever Project: I wanted to get into Arduino projects and introduce my sons to robotics using Arduino. Did you make this project? I had a lot of fun making it and he really liked it. My version is based on Arduino, you may think it is an overkill, but given the flexibility it gave me, I think it is worth it. So many useless machines are built, why building another one? For reference, below are the min/max values I used for each servo as you will see them occurring in the code:The door: 80 hiding, 155 fully openThe hand:  0 hiding, 129 pushing on switchHere is the code (Better to download the file attached to this step instead of copy/paste from below):#include Servo doorServo; Servo handServo; int switch_pin = 2;               //set switch on pin 2 //motor variables int motorThrottle=11; int motorDirection = 13; int motorBrake=8; int pos = 0; int selectedMove = 0;             //move selector int Testmove = 0;                 //test mode: set to move number to test only one selected move                                   //(set to Zero to run normally i.e: roundrobbin on amm moves) void setup() {   Serial.begin(9600);   pinMode(switch_pin, INPUT);   doorServo.attach(9);           //set door servo on Pin 9 pwm   handServo.attach(10);          //set hand servo on Pin 10 pwm   doorServo.write(80);           //set door to hiding position   handServo.write(0);            //set hand to hiding position   //Setup Channel B, (since Channel A is reserved by door and hand servos and can't ber used at same time)   pinMode(motorDirection, OUTPUT); //Initiates Motor Channel B pin   pinMode(motorBrake, OUTPUT); //Initiates Brake Channel B pin } void loop() { if (Testmove != 0) { selectedMove = Testmove; }   //if the switch is on, then move door and hand to switch it off...   if(digitalRead(switch_pin) == HIGH)   {   if (selectedMove > 10) { selectedMove = 0; } //when all moves are played, repeat the moves from beginning   // below are all the "Moves" i designed so far, each is a function that is written below in the code, execuse the names, abit strange?

A useless machine that flips down a switch. 7 years ago … Useless Box DIY Kit Useless Machine Birthday Gift Toy Geek; 6. Great work man! Hehehe. There are essentially 3 sub-assemblies that will make up your Useless machine. A push button to reset the Arduino in case you want to restart the moves/code from top. The useless machine is the second video in the above posting. The code for the useless box is very simple. - it would be great to put the machine in standing position, i know that this will make lose the help of gravity to close the door, but a simple solution is to put 2 rubber bands attached to the inside of the door on one side and to the inner side of the box for the other end, this will make the door close when the door servo is closing...check my build steps,you will see the rubber band in Step 6... - also what about painting the hands in black, it will be more sneaky and slick ! I tried to give this version a character, as I always felt there is somebody "thinking inside the box", so here I tried, I hope I succeeded to give "her" a life! I made my first Arduino project based on this instructable: a useless dragon! 5.
