The Digital Die

1 Inputs and Outputs to generate 1-6

Learn It

GENIE chips can be programmed with several configurations.
We'll need 1 pin to provide power to the chip and 1 pin to tie it to ground.
We'll need 1 pin to program the chip.
We'll need 1 pin to receive an input.
This leaves us with 4 pins to play with.
By right clicking on the GENIE chip in Circuit Wizard, we can choose >Program>Program Settings

Make sure you have a C08 chip sellected.
Now you can use the check boxes to make different pins inputs or outputs.
We're going to want to have as many outputs as possible, so this configuration is probably the best.

Try It

If we want to make a die, we need to be able to represent the numbers 1-6 using LEDs
But we can't simply connect an LED to each output pin, as we only have 4 output pins to use.
Build the circuit as shown below.

Try It

Here's a circuit that allows any number from 1-6 to be displayed by sending output pins high.

Try to come up with your own arrangement, where we could have any number of LEDs fom 1-6, switch on using only 4 outputs.
Screenshot your circuit when you have finished it.

2 A Program for the Die

Try It

We're going to use the circuit shown below to program our Die. It's identical to the one before it, but the LEDs have been placed differently.
Please note: The resistor on G2 is 330 ohms and the resistors on G0, G1 and G4 are 120 ohms.

It's a little hard to construct, so you can download it here
It might help you to understand how the outputs control the LEDs by using the simulation below.

Badge It - Silver

Use the simulation to write down which outputs will need to be set to high for each number the die will generate from 1 through to 6.
Using the diagram below and any graphics package you choose, draw a basic diagram to show how the arrangement of LEDs will be connected to the pins of the GENIE chip.

With this information, you should now be able to create a program to generate the random numbers.
You've quite a bit of experience using flowcharts to program GENIE chips already, so here is the start of the flowchart only.

Badge It - Gold

Use the file you downloaded earlier and your knowledge of which outputs to send high to complete the program and test it to make sure it works.
Take a screenshot of your program when you have finished.

Badge It - Platinum

There are many ways of solving this probems.
See if you can come up with an alternative algorithm that doesn't use the Random block.
Take a screenshot of your program when it is complete.
