The RGB FlasherThe RGB Flasher
The RGB Flasher is an awesome Arduino microcontroller gadget that displays three colors (red, green, and blue) on one LED. You can easily build the circuit on the MakerShield, which will make it portable so you can carry it in your shirt pocket. You can use either the Fritzing diagram shown in Figure 9-4 or the circuit schematic diagram…

Circuit Theory
Figure 9-2 shows a typical RGB LED with the wiring pinout names. There are three pins, one for each color, and one common pin for positive attachment to a power supply. Like the ordinary LED, the positive and negative pins are wired to the positive and negative points of a DC (direct current) circuit. To illustrate, Figure 9-3 shows three SPST (single…
