spectrolum: Spectrometer version 0.020

Version 0.020 is outdated.

xSpectrolum version v0.020

This is the third functional spectrometer in the xSpectrolum series. It was finished on 17 june 2020. It is built on an Arduino Nano board and 9 other modules (breakout boards or components) as shown in the wiring diagram below. All included modules/components are listed below.

xSpectrolum spectrometer version v0.020, the Bluetooth module should be BT10 (not HC05) but when writing this there is no fritzing component for BT10 available.

Spectrometer box

The box holding all the components is similar to version 0.019, including tilted light sources that focus 5 cm from the spectrometer.

Spectrometer solid sampler

The solid sampler fits on the front of the spectrometer box and assures that sampling is confined to the oval opening. All three integrated light sources, the strong led built into the Adafruit 6-channel spectrometer, the SMD 5050 RGB LED, and the red laser all point towards the oval opening.

Spectrometer cuvette holder

Also the cuvette holder fits on the front of the spectrometer box. The steering of the light sources through liquid samples is not finalized.
