Using the 433MHz RF Transmitter and Receiver with Arduino
https://www.electronics-lab.com/using-433mhz-rf-transmitter-receiver-arduino/
While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where communication is one way (Receiving device cannot transmit and the transmitting device cannot receive). Several options […]
Communication Between Two Arduinos Using NRF24L01
https://www.electronics-lab.com/communication-between-two-arduinos-using-nrf24l01/
While building Arduino or any other microcontroller platform project over time the need will arise to establish communication between two of the Arduino boards or microcontrollers for data exchange and/or control. This communication could be achieved using either wired or wireless process. For wireless communication between devices, quite a number of options exist including WiFi, GSM/GPRS, […]

Drones- A Blessing or a Curse?
https://www.electronics-lab.com/drones-blessing-curse/
The increasing popularity of unmanned aerial vehicles (drones) has created a lot of security issues and possible privacy threats. Drone manufacturers have made them easy to fly so that any person without any experience can buy one and fly it without reading the instruction manual first. This has made them attractive for consumers, but also […]
WattUp – RF based Wireless Charging at a Distance
https://www.electronics-lab.com/wattup-rf-based-wireless-charging-distance/
Recently, many big companies such as Samsung have developed wireless chargers which work by induction. These chargers usually consist of a station which needs to be in contact with the device in order to charge. The station defeats the purpose of being able to move and walk while still charging the device. Energeous, a global […]

Ossia has created the world’s first wirelessly-powered alternative to disposable AA batteries. The “Forever Battery” puts a long distance wireless power receiver into an AA battery format. The technology can receive up to 4W from a nearby RF transmitter (Cota transmitter), and includes a data link. [via] Forever Battery bridges the gap between the battery-wire […]
Researchers Develop Long Range Backscatter Sensors That Consume Almost No Power
https://www.electronics-lab.com/university-washington-develops-long-range-backscatter-sensors-consumes-almost-no-power/
Researchers at the University of Washington developed a new backscatter sensors that can operate over long ranges with very little power. The researchers demonstrated for the first time that the device runs on almost zero power and can transmit data across distances of up to 2.8 kilometers. Backscatter communication works by emitting a radio signal and […]
