| − | The Arduino uses the handshake protocol to send characters out. It sends all the ASCII characters from 'A' to 'Z', and starts over. It sends an active-low Strobe signal and listens to an active-low Ack signal. The Arduino waits 1/2 second between each character. Whenever it sends 'A' it activates its yellow LED. This LED blinks ON every 13 seconds approximately, and stays on for 1/2 second (26 characters * 0.5 sec). | + | The Arduino uses the handshake protocol to send characters out. It sends all the ASCII characters from 'A' to 'Z', and starts over. It sends an active-low Strobe signal and listens to an active-low Ack signal. The Arduino waits 1/2 second between each character. Whenever it sends 'A' it activates its yellow on-board LED. The LED is turned off when a 'B' (or any character other than 'A' is sent). This LED blinks ON every 13 seconds approximately, and stays on for 1/2 second (26 characters * 0.5 sec = 13 sec). |
Your assignment is to design a system that will use and LED that will blink synchronously with the Arduino. The LED should stay on for about 1/2 second. | Your assignment is to design a system that will use and LED that will blink synchronously with the Arduino.
