Blinking LED using Arduino UNO
-
It is the simple basic project created using Arduino. LED (Light Emitting Diode) is an electronic device, which emits light when the current passes through its terminals. LED's are used in various applications. It is also used as an ON/OFF indicator in different electronic devices.
In this project, we will connect the LED to the digital pin on the Arduino board. The LED will work as a simple light that can be turned ON and OFF for a specified duration.

@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.
