Serial. Serial1.println("Initialize Serial Hardware UART Pins") Serial1.begin(9600) //This is the UART, pipes to sensors attached to board Serial.println("Initialize Serial Monitor") Serial.begin(9600) //This pipes to the serial monitor TX LED is set as an output behind the scenes PinMode(RXLED, OUTPUT) // Set RX LED as an output (We could use the same macros for the RX LED too - RXLED1, So, far, you havent defined how long the pause while the pin is on should be, so the fact that it is not to your liking is hardly surprising. macros (TXLED1, TXLED0) to control that. By turning the pin on, pausing, turning the pin off, pausing, and repeating, the LED connected to the pin can appear to blink. Note: The TX LED was not so lucky, we'll need to use pre-defined Int RXLED = 17 // The RX LED has a defined Arduino pin To explain the difference between Serial.print() and ProMicro's TX and RX LEDs within a sketch.

Where can I get the code for the program "Blink"?.How do I select the board I have in the Arduino software?.How do I run the program "Blink" on my board?.Is the constant red LED a common issue? And how do I solve it?.(the board has 2-3 LED:s) – But after having ran a pasted-in version of the program "Blink" that i believe i got from some website that a video linked to, the board seemed to have broken for I am no linger getting that "random"-like blinking anymore, just one red light that is constantly on. At first my board, which I believe to be a "Pro Micro" (but I need to verify this, how do I get to know which board I have?), was blinking yellow and green a little "random"-like when plugged into my laptop.I watched a few videos about how to set up my board with the "Blink" program a while ago (I prefer learning by reading), but ran into some problems: I am very new to Arduino, but I'm decent at programming in JS and HTML.
