Electronic for Chemists_ The Spectrometer

This book is the second in a series of publications on the application of electronics and robotics to the manufacture of chemical laboratory equipment. Building on the series 'Electronics for Chemists', it is a logical continuation of the previous book about 'Conductimetry' which aim to introduce chemists and physicists to designing laboratory equipment to create an autonomous, low-cost 'ChemLab'.

UV-visible spectroscopy is one of the most widely used analytical techniques in chemistry. It enables the identification of coloured compounds, the monitoring of reactions, and the precise quantification of species alone or with a co-reagent.

This book helps non-chemists to understand the origin of the colours of the compounds around us, as well as how to accurately measure complex compounds. It also allows others to approach the electronics of RGB LEDs, the reconstitution of light through the principle of addition, signal amplification and simple processing by an Arduino card. It is an excellent project for any apprentice wishing to develop their skills in this field of “Electronics for Chemists.”

Let's not forget that we cannot expect a chemist to become an expert in electronics and data processing ... However, we can educate him or her in the simple and basic principles. We invite chemists to participate in the open source movements to enrich himself and the community of "hackers" and "doers". In this sense, this book has been written in the hope that readers will fill in the missing pages!
