I could switch any of the 3 LED banks between off, auto or on as needed, and the moment I stepped inside into the light, it automatically shut off unless I manually overrode it.
The LED's intensity is good at V S =1.5V (equivalent to a fully charged alkaline cell) and remains acceptable with V S as low as 1V. The circuit should find applications in toys, security devices, ...
This circuit diagram joins a cell, a switch and two bulbs. ... In an LED electrical energy is almost all converted into light energy with almost none wasted as heat.
Gene expression is a fundamental of life, where each cell switches on and off specific genes. Thus, an autonomous device that could control the on-off switching would have great value in medical care.
