Audio Line Receiver using INA134
https://www.electronics-lab.com/audio-line-receiver-using-ina134/
The project described here is a differential line receiver consisting of high-performance INA134 OPAMPs with on-chip precision resistors. The project is fully specified for high-performance audio applications and has excellent AC specifications, including low distortion (0.0005% at 1kHz) and high slew rate (14V/µs), assuring good dynamic response. In addition, wide output voltage swing and high […]
Balanced Line Receiver for Digital Signal Over Twisted Pair CAT-5 Cable
https://www.electronics-lab.com/balanced-line-receiver-for-digital-signal-over-twisted-pair-cat-5-cable/
The circuit presented here is a high-frequency differential line receiver amplifier that has excellent common-mode rejection at its inputs. The project is an ideal solution for a receiver of a digital signal or video signals that are transmitted over long distances on twisted-pair cables like CAT5. Category 5 cables are very common in office settings […]

Wireless communication between two Arduinos using inexpensive RF modules
https://www.electronics-lab.com/wireless-communication-between-two-arduinos-using-inexpensive-rf-modules/
Raj from Embedded Lab has posted a new article exploring an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules. He used a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless temperature and humidity monitor. Wireless communication between two Arduinos using inexpensive […]

by liwenyip @ instructables.com: In this tutorial I’ll show you how to use an Arduino to decode signals from RF remotes, and re-send them to remotely control some mains switches and a garage door. Decoding and sending 433MHz RF codes with Arduino – [Link]
Simple Infrared Barrier
https://www.electronics-lab.com/simple-infrared-barrier/
by Maurizio @ dev.emcelettronica.com: Although a remote control is not so difficult to design and build, there is an even simpler option: the IR barrier. This consists of a constant IR signal permanently going from an emitter to a receiver, both of them being in two different places (a few meters apart). When an obstacle comes […]
Simple Acoustic Guitar Sound Receiver
