Get these awesome clear 5mm tri-color LEDs! Inside, there are separate red, green, and blue LED chips. They're great as bright indicators or illuminators, and it's really fun to create color swirls with them. With an 80-degree viewing angle, you can easily plug them diagonally into a breadboard. These are Common-Anode type. Just connect one pin to around 5V and then connect the other three legs to the ground through a resistor. We use CA more than CC because many multi-LED driver chips, like the TLC5940/TLC5941, are designed only for CA and can't be used with Common-Cathode. The LEDs are square, 0.3'/7.6mm on each side, sometimes called 'Super flux' or 'Piranha'. They have a clear lens and an 80-degree viewing angle. The red LED has a 630 nm wavelength, green is 525 nm, and blue is 470 nm. At 20mA current, the forward voltage for red is 2.1 - 2.5V, green is 3.8 - 4.5V, and blue is 3.8 - 4.5V. The typical brightness is 400 mcd for red, 1200 mcd for green, and 400 mcd for blue (total 2000 mcd). Check the BL-FL7680RGBC Datasheet for more details. If you need help using LEDs, read our 'Introduction to using LEDs' tutorial for your electronics projects.
Using these LEDs is easy. First, you'll notice they're Common-Anode type. Connect one pin to around 5V. Then, connect the other three legs to the ground through a resistor. You can plug them diagonally into a breadboard. When it comes to creating colors, you can play around with the red, green, and blue LED chips inside to make different color combinations. As for the viewing angle, it's 80 degrees, so you can see the light clearly from a good range. When using them in an electronics project, if you get stuck, refer to our 'Introduction to using LEDs' tutorial. As for maintenance, keep them in a dry place and avoid getting them wet. Also, don't expose them to extreme temperatures. If you want to know more technical details, check the BL-FL7680RGBC Datasheet.
