• STAT1 — This blue indicator LED toggles on/off when a new
character is received. This LED blinks when serial communication is
functioning.
• STAT2 — This green LED is connected to Arduino D13 (SPI Serial
Clock Line/ATmega328 PB5). This LED only blinks when the SPI
interface is active. You will see it flash when the OpenLog records
512 bytes to the microSD card.
Hardware Hookup
You are going to love this! First thing is that you need to insert a microSD
card into the OpenLog with the text side "up" as shown in the image below.
Make sure the card "clicks" into place and stays in place.
Next insert the OpenLog's pins into the serial port on the weather:bit carrier
board as shown below. Make sure that all of the pins are aligned and
inserted correctly. Offsetting these pins could end in damaging your
OpenLog or micro:bit. Finally, if you haven't already, plug your micro:bit into
the weather:bit. With that you should be good to go!
