Relay flickering while connecting arduino
-
While connecting Arduino with Relay module (Not self made) some times it flickering. May be due to back EMF. How can I avoid this problem.

One thing you can try is having a diode. It basically allows current in only one direction. And we need more info about how you have connected the circuit and stuff. Please share more info.

@codelery said in Help needed: Arduino Wireless Notice Board project:
I am using the hardware serial (pin 0 and 1 on Arduino Uno)
As @rafitc99 mentioned, you need to expand the Serila buffer, in the hardware serial also the Arduino board package implements a 64-byte ring buffer for send and receive on the hardware serial messages. So you need to change that to 256 as per your message length.
