“Hello World” Running Arduino IDE Serial Monitor on Gertboard

 So you have tried the following code and include Serial.println(“Hello World!”); in your sketch yet nothing happens?

To see printed messages on the Arduino IDE Serial Monitor,  you need to link up the broken-out Raspberry pins as follows: 

• Raspberry Mini UART TXD (GPIO pin 14) -> Gertboard MCRX (1 jumper)
• Raspberry Mini UART RXD (GPIO pin 15) -> Gertboard MCTX (1 jumper)

Just use 2 pin jumpers side by side like this. The red mark represent jumpers.

Test it again.

Done!
