This paper examines the modulation of proteinoid spiking frequency in response to light. Proteinoids are proteins formed through thermal condensation of amino acids and have been found to exhibit spiking behaviour in response to various stimuli. It has been demonstrated that their properties can be modulated by light, with the frequency of spikes changing in response to varying light intensity and wavelength. This paper explores the underlying mechanisms of this phenomenon, including how light affects the proteinoid's structure and its effect on the spiking frequency. We also discuss the potential implications of this modulation for future research and applications. Our research findings suggest that light could be used as a tool to regulate the spiking frequency of proteinoids, opening up a new range of possibilities for unconventional computing research.
