Parts included:

• One 33k resistor
• Two 10k resistors
• One Light Dependent Resistor (LDR)
• One 8×8 Red LED Matrix - Common Cathode
• One 10uf Capacitor
• One 0.1uf Capacitor
• One 24 Pin DIP Socket
• One MAX7219 LED Driver IC
• One PS2 style joystick
• One joystick cap
• One Beta Shield PCB

Assembly:

Insert resistors and capacitors as labeled - solder connection on the bottom. Trim excess leads.

Insert LDR in oval spot next to 10 k resistors. Solder connection on bottom. Trim excess leads.

Insert joystick into position - solder connections on bottom. It only fits one way.

Insert DIP socket and solder connection on bottom.

Insert 8×8 LED Matrix with the black writing on the edge of the Matrix facing downward to the bottom edge of the board - NOT facing the capacitors. Solder connections.

Insert MAX7219 into socket - with the key facing the right edge of the board - not facing the capacitors.

Snap joystick cap on to joystick.

Insert two 9 pin male headers from the bottom of the PCB and solder on the top - plug Digispark Pro with female headers into the bottom.

Use the LED control library to control the LED Matrix (included with the IDE addons) - use the following init string for proper pin settings:

/*
 pin 10 is connected to the DataIn 
 pin 11 is connected to the CLK 
 pin 12 is connected to LOAD 
 We have only a single MAX72XX.
 */
LedControl lc=LedControl(10,11,12,1);

The joystick is an X and Y potentiometer which shows a voltage on A5 and A8

The push button pulls Pin 1 high.

The LDR reports a voltage on A9 based on the light level.

The pins are written on the board itself for reference as well.
