Nite Rider LEDS
As a keen cyclist I am always looking for ways to be seen at night. I wanted something that was a novelty and would catch the motorists eye. So looking around ...
LED VU Meter with LM3914N
The circuit is based on an LM3914N bar graph display driver device (IC1), which can be used to drive up to ten LEDs. This is connected so that with OV12 at the ...
simple self-powered circuit
This simple circuit is started running by connecting a twelve volt battery across the terminals, causing the large diameter Light-Emitting Diode to light up. Wh...
