1 PICAXE 18X Microcontroller
1 serial socket
1 22kOhm resistor
1 10kOhm resistor
lots of black multicore wire
lots of red multicore wire
Once you have the parts, it’s time to connect them all together.The first board he began soldering on was the display board.Once this was complete he started soldering the LEDs.
