**DIGI-DICE 6 LEDs and Numbers**

Basic System Diagram

**INPUT**
A Mechnaical switch - such as the Push Button or one of its variations

**PROCESSOR 1**
RC1 Controls the Timing of the Roll-Down

**PROCESSOR 2**
4046-VCO Clock Output

**PROCESSOR 3A**
4017 Walking Ring Decade Counter to control LEDs 7th Output (o6) connected to Reset and Controls on 4510

**PROCESSOR 3B**
4510/4511 clock signal in to 7 Seg. Display Output

**PROCESSOR 4**
Timed Off as a power saver. RC3 Controls the Transistor that cuts powere to the LEDs

**OUTPUT-1**
6 LEDs

**OUTPUT-2**
7 Segment LED Counting 1/2/3/4/5/6

**OUTPUT**
7 Seg. Display Each Display is supported by a 4510/4511 set

Graphic System Diagram

**First Section including the 4046**
Input	Processor	Output
Push Button closes Voltage Filling RC 1	Falling Voltage controlled by the RC 1 drains from max to minimum. The voltage at pin 9 is compared to V+. This controls speed of Voltage Controlled Oscillator	Length of Rolldown controlled by RC 1. Rolldown Clock Signal.

**Second Section 4017**
Active Inputs	Processor	Output
Clock Rolldown From the Output of the 4046 Reset	1 of 10 counter reset at out6.	Walking Ring Provides Hi to out0 to out6. out6 is used to reset 4017 to 0 out 6 is used as contolling input to 4510

**Second Section LEDs**
Input	Processor	Output
Walking Ring Provides Hi to 1 of 6 LEDs in sequence.		Light

**Third Section starting with 4510**
Input	Processor	Output
Clock Rolldown from 4046 Hi input from 4017 out6 triggers preload of L1 U/D Counter set up or down	Decimal Counting Binary	Advancing Binary Code

**Third Section 4511**
Input	Processor	Output
Binary Word	Converter for 7 Segment LED Binary Counting Decimal	Decimal Value of Binary Input shown on the 7 segment LED

**Fourth Section Timed Off**
Input	Processor	Output
Voltage Filling RC 3	Transistor opens then slowly closes the connection to ground as controlled by RC 3	Displays Fade Out
