+The ATmega328 microcontroller supplied with the kit has a specially modified version of the Arduino bootloader pre-programmed into it, together with an initial program to flash the red LED.
-Arduino usually has a LED wired to Digital pin 13, but in Nanode, digital 13 is in almost constant use as the SPI Clock.
+Arduino usually has a LED wired to digital pin 13, but in Nanode, digital 13 is in almost constant use as the SPI Clock so in the Nanode bootloader the LED flashing function has been altered so that it flashes the red LED which is wired to digital pin 6.
-So in the Nanode bootloader, the LED flashing function has been altered so that it flashes the red LED which is wired to digital pin 6.
+If all is well with your Nanode board the red LED should start flashing about 2 seconds after the power (from USB or FTDI cable) has been applied.
-If all is well with your Nanode board, the Red LED should start flashing about 2 seconds after the power (from USB or FTDI cable) has been applied.
 If it does not flash, check for faults such as missing soldered joints or the LED incorrectly inserted.
