Make An Electronic Dice Without Microcontrollers!




For detailed instructions, visit: http://www.instructables.com/id/Ten-Breadboard-Projects-For-Beginners/

Intro:

Have you heard about electronic dice before? If not, it is a simple dice but instead of shaking it you have to press a button. The device will tell you a random number between 1 and 6 through a series of LEDs. The number of LEDs that light up will indicate the number. This project uses a 4060 counter that counts the clock pulses received sets a particular number of pins high. Pressing the button creates a fast clock pulse so the pins that would be high cannot be estimated. This is the reason that makes this dice a completely random number generator. The pins that are set high light up a series of leds that indicates the number. The good thing about this project is that it does not use any microcontrollers thus making it non- programmable thus making it cheap. Most of the projects that you may have seen require arduino or other microcontrollers. Truly speaking, this is the most tedious and time consuming project.

Instructions:

Connect everything according to the layout given above. Make sure you connect everything properly as the connections are too many. Switch the circuit on and press the button. A certain number of LEDs will light up indicating the number which is completely random. Connecting the LEDs like a real dice in a certain order forming a rectangle would make the project look more good.

Parts list:

  • 1x 4060 ic
  • 1x 2.2M resistor
  • 1x 470K resistor
  • 1x 100K resistor
  • 1x 560 ohm resistor
  • 1x 470 ohm resistor
  • 1x 220 ohm resistor
  • 2x 1n capacitors
  • 2x 1n4148 or 1n4001 diodes
  • 6x LEDs
  • 1x Momentary push button
