Description: My goal is to create a modern telegraph machine that replaces the subjective interpretation of “dots”, “dashes” and “spaces” with independent objective buttons to hopefully improve functionality, speed and online delivery. Goals: Send...
Lesson Learned: Controlled by Arduino Controller Off-line. Use const to keep track of pin numbers for buttons and leds It is SO easy to fry a board: Always connect GROUND before you connect POWER...
Lessons Learned: Unplug and plugin Arduino USB to create dynamic MAC OS drivers! 220 Ohm resistors for LED Lights — 10K Ohm resistors for buttons. Sample Code: // the setup function runs once when...
Three interactive buttons and LED lights. Stand alone hardware check. Green = DOT Yellow = DASH Blue = SPACE
Interactive button to turning on/off green LED light.
