- Digital Dice Module on NI ELVIS II Protoboard 2. Use the NI-ELVISmx Digital Writer as a diagnostic test instrument to stimulate your circuit. Recall that the LEDs are active LO. Use the values A, B, C, and D in Table 11.0 to verify the operation of your design.
- Here is the circuit diagram of a LEDs based digital dice which is nearly unbiased. The main advantage of this circuit is that there is no chance to cheat as the circuit operates at such a high speed that the circuit is almost imperceptible to the human eye.
- Operation of Unbiased Electronic Dice with LEDs This circuit uses 555 timer as an astable multivibrator. In this mode, the circuit is arranged with R2 = 100 KΩ, R3 = 100 KΩ and C2 = 0.1 µF. With this configuration, the circuit operates as a pulse generator with a frequency in order of kilo hertz.
Unbiased Digital Dice with LEDs By Sudheer Gupta (Contributed Content) Wednesday, February 20, 2013 Here, we are going to show you a digital dice which is nearly unbiased. There is no chance to cheat as the circuit operates at such a high speed that the circuit is almost imperceptible to the human eye. This is a simple and easy to construct digital dice circuit. The circuit is based on a single IC, CD4060B.The dice consists of six LEDs marked D1 to D6.The number of LEDs glowing indicates the numeral. The heart of this circuit is 14 stage binary ripple counter IC CD4060B.The IC also has a built-in.
This is the Electronic Dice Kit. This well-designed project will result in a useful Electronic Dice that you can use anywhere that a Dice is required. This is an advanced project due to the small components used and how it needs to be put together.
To operate the Dice, simply hold down the Pushbutton and release it after a second or two. All of the LEDs will light up and slowly go through the numbers until it randomly stops on a number from 1 to 6.
Use this Electronic Dice when playing any of your favorite games. It comes with White LEDs but you may substitute any color you like. This electronic circuit is the first in a series of fun hobby kits designed to fit the small hinged enclosure.
The circuit requires a 9v battery which is not provided. You will get a schematic, instructions, and all of the parts to assemble a working unit. This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc.
Tons of LED dice projects with different output forms have been published online. The most common output configuration in those projects is a 3-1-3 setup (two rows of three LEDs and one LED at in the middle) of seven LEDs, which simulates the actual patterns of dots found on the six faces of a traditional dice. When it is rolled, one or more LEDs are selectively turned on to display a random number between 1 to 6. This project is about a similar LED dice but with a slightly different output form. It uses 6 LEDs which are arranged in a circular pattern and are labeled 1 through 6. They create a chasing effect when the dice is rolled. The chasing effect slows down gradually, and eventually stops at one of the six LEDs. The rolling is done by a gentle shaking of the dice horizontally. The LED dice is powered with a 3V coin cell battery and uses PIC12LF1822 microcontroller to generate a random number and drive the output LEDs.

The six LEDs are driven through 3 I/O pins of PIC12LF1822 microcontroller using the Charlieplexing technique. Three 100 Ohm resistors are placed in series with the I/O lines to limit the LED currents. A horizontally placed tilt switch (also known as vibration switch) is used to sense the shaking of the dice. A tilt switch is simply a tube with a tiny conductive metal ball that rolls inside it, and has two electrical contacts that are accessible from external leads. When its tilted upright, the ball rolls onto the two metallic contacts, thus short-circuiting them together. The tilt sensor along with a pull up resistor generates an interrupt signal on GP2/INT pin of the PIC12LF1822 microcontroller and the dice is rolled. A power on/off slide switch is also included in the project. In case you forgot to turn it off, the PIC microcontroller will be programmed to automatically go to sleep mode to save the power consumption. A circular shape PCB is designed for this project. The CR2032 battery holder is placed on the bottom side of the PCB, whereas rest of the electronics and LEDs go on the top side.
