Synchronizing an LED array with a motor
In the previous sections of this chapter, we learned about controlling an LED array and DC motor using Arduino:
Once you have connected the circuit as shown in the preceding image, upload the following code to Arduino. In the following code, we are writing the "Hello world" of persistence of vision:
int LEDPins[] = {2, 3, 4, 5, 6, 7, 8, 9};
int noOfLEDs = 8;
//data corresponding to the each alphabet and a few characters to be displayed
byte H[] = {B11111111, B11111111, B00011000, B00011000, B00011000, B00011000, B11111111, B11111111};
byte E[] = {B00000000, B11111111, B11011011, B11011011, B11011011, B11011011, B11000011, B11000011};
byte L[] = {B00000000, B11111111, B11111111, B00000011, B00000011, B00000011, B00000011, B00000011};
byte O[] = {B00000000, B11111111, B11111111, B11000011, B11000011, B11000011, B11111111, B11111111};
byte fullstop[] = {B00000000, B00000000, B00000000, B00000011, B00000011, B00000000, B00000000, B00000000};
