This chapter continues working with analog signals, sending voltages from the EV3 Intelligent Brick to the Arduino. The previous chapter had signals going from the Arduino to the EV3; in this chapter, the reverse is being done. An example application is developed of the EV3 Intelligent Brick sending commands to select different patterns on an LED array. This LED array, shown in Figure 6-1, is a line of ten LEDs that can be programmed by the Arduino to light up each LED in color and brightness. Three buttons on the EV3 Intelligent Brick will select which of the ...
