Light Emitting Diode LED has revolutionized entire globe with one of the most fascinating spectrum as source of light. A littleBits component that easily lev this interface requirement is a proto module as shown in Figure 6.


In other words, make sure the hardware is working with matfix simplest code you can. The 4-bit binary counter needs a digital clock to sequence the numerical data in the correct counting order. Figure 3 shows the electronic circuit schematic diagram for the littleBits pulse bit. Once the breadboard wiring is completed, the littleBits modules can be attached and wired to the correct solderless breadboard locations.
