Useless Box 2015 - Arduino Edition

thingiverse

I have designed this innovative machine based on the Arduino UNO platform, featuring two distinct operation modes. The first mode operates in a traditional manner, while the second mode is activated when the power is off with the switch set to ON, enabling a predetermined function accompanied by random movements. The device can be powered through a 9V battery, USB connection, or an external power supply. To experience this machine in action, please refer to the YouTube video at http://youtu.be/ePExtkO2ebE. Below is a list of materials required to build and assemble this device: Instructions: Materials Required (A): 1. Arduino Uno R3 or compatible 2. Microservo SG90 or equivalent model 3. 9V battery 4. Battery Connector 5. Power switch for the 9V battery, size 9x14mm 6. Power button 7. Optional spring component 8. Some screw, wire, and spare time Wire Connection (B): Servo: Connect the RED wire to the 5V pin. Connect the Black or Brown wire to GND. Power Button: Connect one end of the wire to pin 10 and the other end to GND. Assembly Instructions: 1. Print all parts. 2. Mount the door on top of the case by pushing it into place. 3. Solder wires to their respective pins as indicated in table B. 4. Install the button switch while ensuring proper orientation. 5. Attach the power button and battery mount components together. 6. Secure any loose wire using adhesive for added stability. 7. Insert the 9V battery into the case through an opening that is provided for this purpose. 8. Complete the assembly by mounting the cover for the power switch component. 9. Utilize Arduino IDE to compile a suitable sketch and send it over to your Arduino Uno board.
