* **Center Frequency:** The center frequecy should be set to the resonant frequency of the cell. The firmware will set the frequency of the green laser to the center frequency. It will set the frequency of the blue laser to the center frequency - 3 Hz and the red to the center frequency + 3 Hz.

* **Blue Laser:** The laser connected to pin 0. * **Blue Laser:** The laser connected to pin 1.
* **Green Laser:** The laser connected to pin 1. * **Green Laser:** The laser connected to pin 4.
* **Red Laser:** The laser connected to pin 2. * **Red Laser:** The laser connected to pin 9.
* **Frequency Sweep:** Begin at center_frequency - n Hz and increase the frequency by 1 Hz every 2 seconds until reaching center_frequency + n, where *n* is any integer. *This is not currently useful -- use the sweep software instead!* * **Frequency Sweep:** Begin at center_frequency - n Hz and increase the frequency by 1 Hz every 2 seconds until reaching center_frequency + n, where *n* is any integer. *This is not currently useful -- use the sweep software instead!*
* **Indicator LED:** By default, the Pico will flash the on-board LED when powered on. This may be turned off with `toggle.off`. * **Indicator LED:** By default, the Pico will flash the on-board LED when powered on. This may be turned off with `toggle.off`.
