The aim is to develop a low-cost, easily assembled visible spectrometer for educational use.
Constructed a visible spectrometer using a microcontroller, optical components, and 3-D printed materials.
Utilized a C++ program to operate the microcontroller and collect data from the optical sensor.
Connected the device to a laptop to record data in real-time using Excel with VBA programming.
The built spectrometer provided similar species concentration readings to commercial spectrometers.
Effective for educational laboratory exercises in quantitative analysis and instrumental methods.
