The circuit, composed of a bulb, a photoresistor, a thyristor and a linear resistor, corresponds to a nightlight device whose light is looped back into its light sensor. Periodic bifurcations and deterministic chaos are obtained by the feedback loop created when the thyristor switches on the bulb in the absence of light being detected by the photoresistor and the bulb light is then looped back into the nightlight to switch it off. The experimental signal is analyzed using tools of delay-embedding reconstruction that yield a reconstructed attractor with fractional dimension and positive Lyapunov exponent suggesting chaotic behavior for some parameter values. We construct a simple circuit model reproducing experimental results that qualitatively matches the different dynamical regimes of the experimental apparatus. In particular, we observe an order-chaos-order transition as the strength of the feedback is varied corresponding to varying the distance between the nightlight bulb and its photo-detector. A two-dimensional parameter diagram of the model reveals that the order-chaos-order transition is generic for this system. <\/jats:p>","DOI":"10.1142\/s0218127416500802","type":"journal-article","created":{"date-parts":[[2016,5,31]],"date-time":"2016-05-31T06:25:31Z","timestamp":1464675931000},"page":"1650080","source":"Crossref","is-referenced-by-count":3,"title":["Optoelectronic Chaos in a Simple Light Activated Feedback Circuit"],"prefix":"10.1142","volume":"26","author":[{"given":"K.
