a 5 V from the Arduino and the transmitter. He designed the receiver side with equal care. Conceptually the circuit there is simple, consisting of the ultrasonic receiver, followed by a transistor ...

The transmitter and receiver circuits of the infrared alarm system shown here have been designed for a range of several meters, almost independent of ambient light conditions. Only in the rare case of ...

[GreatScott] does exactly this in the video after the break, building both a transmitter and receiver ... testing two popular 555 transmitter circuits. One uses the control voltage pin to input ...

Here are some DIY FM Transmitter circuits that we have been published on electroschematics.com. This do-it-yourself fm transmitters are pretty easy to build and will give you a good feeling when ...

Researchers have developed a tiny unit that is both an optical transmitter and a receiver. Researchers at ... integrated with traditional electronic circuits. "We have managed to integrate optical ...

dc power applied to the transmitter circuit causes the transmit coil to generate an ac magnetic field that induces an ac current in the receive coil, which then powers the receiver circuit that ...

Simplifying the wireless power system, these transmit power optimization and foreign object detection features in the LTC4125 do not require any direct communication between the transmitter and ...
