b'CODE TO NOTESerial commands can be used to send and receive data from your computer. This line of code tells the RedBoard that we SERIAL BEGIN: want to begin that communication with the computer, the same way we would say Hi to initiate a conversation. Notice Serial.begin(9600); that the baud rate, 9600, is the same as the one we selected in the monitor. This is the speed at which the two devices communicate, and it must match on both sides.We use the analogRead() function to read the value on an ANALOG INPUT: analog pin. analogRead() takes one parameter, the analog potPosition =pin you want to use, A0 in this case, and returns a number analogRead(A0);between 0 (0 volts) and 1023 (5 volts), which is then assigned to the variable potPosition.This is the line that actually prints the trimpot value tothe monitor. It takes the variable potPosition and prints SERIAL PRINT: whatever value it equals at that moment in the loop(). The Serial. ln at the end of println tells the monitor to print a new println(potPosition);line at the end of each value; otherwise the values would all run together on one line. Try removing the lnto see what happens.CODING CHALLENGESCHANGING THE RANGE: Try multiplying, dividing or adding to your sensor reading so that you can change the range of the delay in your code. For example, can you multiply the sensor reading so that the delay goes from 02046 instead of 01023?ADD MORE LEDS: Add more LEDs to your circuit. Dont forget the current-limiting resistors. You will need to declare the new pins in your code and set them all toOUTPUT . Try making individual LEDs blink at different rates by changing the range of each using multipilcation or division. 24 : circuit 1b'
