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, ...

A new trial just getting underway at Scripps Research Institute in La Jolla is using two novel medications in combination to ...

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.

Output components, including LEDs, bulbs, buzzers, and motors, respond to signals from the circuit. Power supplies, like single-cell and multi-cell batteries, as well as AC power supplies, provide ...

Removing either LED does not break the circuit, either, because current can still flow through the other LED to complete the circuit. In a parallel circuit, all the LEDs you connect will glow no ...
