Lamp dimmer using NE555

Lamp dimmer using NE555

lamp dimmer. . Lamp dimmer using NE555. This project is about simple lamp dimmer project using NE555 timer IC. PWM method is used for controlling the brightness of the lamp. This method is very power efficient and low cost compared to linear power control circuits. In PWM method the load is driven u...

...vel 4 foot, diodes D5 ended, 11 feet output low level, thyristor VT ended, lamp light. When dark, photosensitive resistance tolerance is larger, the ends of the voltage, CD4011 1 foot into a high level, this is if there is no voice, two feet to be low, the output end is always 3 H, with the same dur...

Important. Please review New EasyEDA libs.

...mpared to other (tiny) icons (e.g. sources), also see TR1 and Q6, speaker, lamp, meter and logic gates. Transistor (discrete) don’t have circles any more?. Thanks. I will answer your questions after we provide the feature. It is coming soon. Do you think EasyEDA can be public after this feature?...

...uilt this circuit on a perf board and it seems to function well as the led lamp draws a max of 500 mA. It is a larger lamp (flashlight style). I was using a much larger load transistor (tip120) but that's just too big. I chose the transistor in the schematic because of it's 600 mA rating. I should...
