The Arduino Pro-Micro then uses it's 9 analog inputs to read ... This replacement part is 850nm compared to the phototransistor which is 880nm, but the spectrum overlaps enough and the two devices are ...

Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to ...

Whether you're a newbie just getting started with electronics and embedded systems or a professional Engineer planning your next big design project, Arduino has you all covered with a development ...

Simultaneously, the Arduino output pin D3 of the Arduino sends a voltage. This voltage causes the LED in the optocoupler to emit light, activating the photodiode and forming a short circuit between ...
