My Light Diagram

Description With this electronic dice the result is displayed with LEDs that are placed so every dice face is shown. In the circuit diagram, IC 4022 is used to count to 6 in which only one output can get “1″ state. A diode matrix (D1..D8) serve as decoding the output signals of the counter so that the LEDs are controlled by two buffer transistors and series resistance.  Integrated circuit outputs only support a reduced load, so in the transistor’s base are connected the limiting resistances. As a clock generator it can be used any generator with rectangular pulses whose amplitude corresponds to the IC’s supply voltage. The 4022 clock input impedance is 10 12 Ω.  Circuit Diagram  Source - http://electroschematics.com/5011/electronic-dice/

Simple Dice With 7-Segment Display Circuit Project. A simple digital dice circuit can be easily realised using an astable oscillator circuit followed by a counter, display driver and a display. Here we have used a timer NE555 as an astable oscillator with a frequency of about 100 Hz. Decade counter IC CD4026 or CD4033 (which-ever available) can be used as counter-cum-display driver. When using CD4026, pin 14 (cascading output) is to be left unused (open), but in case of CD4033, pin 14 serves as lamp test pin and the same is to be grounded. Digital Dice With 7-Segment Display Circuit diagram The circuit uses only a handful of components. Its power consumption is also quite low because of use of CMOS ICs, and hence it is well suited for battery operation. In this circuit two tactile switches S1 and S2 have been pro-vided. While switch S2 is used for initial resetting of the display to ‘0,’ depression of S1 simulates throwing of the dice by a player.  When battery is connected to the...
