Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
