Nettet1) Disconnect everything from Arduino especially from Tx Rx pins, and try to dump the blinky sketch. If it works, then arduino is good. If it doesn't work, follow this article to burn a fresh bootloader in your atmega. Check again. If not able to burn bootloader or code afterwards, get a new atmega IC for cheap and replace the damaged one.

RX and TX flicker whenever the Arduino is sending data to the PC (TX) or is receiving data from the PC (RX). If you have never re-programmed your Arduino, it is running whatever code was in it when it was …

NettetWhen an Arduino's pin is configured as a digital output, the pin's voltage can be programmatically set to GND or VCC value. By connecting the Arduino's pin to LED's anode (+) pin (via a resistor), we can programmatically control LED's state. Wiring Diagram We are going to run through two examples: NettetAfter that, when I powered the board to upload another program, 4 LEDs (L, TX, RX, ON) went red without blinking. So now, every time when I power up my Uno board, without any connection with any of the pins previously mentioned, the 4 LEDs are red coloured all the time. arduino-uno led bluetooth error rx-pin Share Improve this question Follow
