This comprehensive light source set includes an assortment of 50 or more LEDs in red, green, blue, yellow, and white. These LEDs are THT (through-hole) package types, available in 3 mm and 5 mm sizes, and are fully compatible with breadboards and educational microcontrollers like Arduino. They operate with a nominal forward voltage of 1.8 to 3.3 V and a current of up to 20 mA. Additionally, the kit features training-use light bulbs with E10, G4, or similar base types. These bulbs support a nominal voltage range of 3–12 V and use either incandescent or LED light sources. Power can be supplied via batteries or an external low-voltage source.
