In a prior week I produced 2 pwm small motor drive circuits so this week I experimented with 2 layer PCBs using the vinyl cutter. I produced standard and a modified LED array boards.
For this weeks project I modified and produced the hello.44.array board to interface with the FabKit board.
Bottom Copper layer.
Layer with Vias.
Top Copper layer.
On the mill.
On the Vinyl cutter.
Base layer on mill.
Three layers of board.
Via area on PCB prepared and additional layers prepared to transfer.
Final assembly weeding and stuffed board.
Board connected to FabKit and in operation.
Arduino code - the translation of hello.array c program - fa_led_array.pde.
Arduino code - displaying a historical bar graph of light input - fa_led_array_delay_graph.pde.
