all the way to digital output

Note: It is very easy to use the Hi-Watt 9V Battery in any circuit but get a battery snap connector so that you can easily replace the discharged battery and also it is much easier to use without having to solder the wires on the terminals of the battery

When an appropriate voltage is applied to the LED terminal

The digital output (D0) can be used for simple detection logic

5mm White Blue Led (Pack of 10) Integrated Circuits There are four rows and5mm White Blue Led (Pack of 10) A white blue light emitting diode (LED) is a semiconductor light source. LED's are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white led and illuminate's blue light. When a light emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the
