Abstract: Direct digital-to-RF conversion at the antenna interface offers many exciting opportunities to push the performance envelope of RF transmitters in efficiency, area, signal bandwidth, and ...

Abstract: Thermoelectric generator (TEG) converts heat energy into electrical energy when there is a temperature gradient between top and bottom surface of the device. Generally, large electronic ...

1. LEDs- its used as an indicator to show that the receiver is receiving a signal. 2. Resistors-help to reduce the flow of electric current 3. HT12E- it is an encoder which is used to encode ...

These days, transmit- and receive modules that operate on the well-known 433-MHz licence-free frequency are reasonably cheap and freely available at electronics stores. The circuit described here ...

In this project, we’re making an ordinary two-wheeler helmet smart using an RF Transmitter & Receiver. The best part: this Arduino-based smart helmet is simple to build and does not require advanced ...

Making our projects Wireless always makes it to look cool and also extends the range in which it can be controlled. Starting from using a normal IR LED for short distance wireless control till an ...

In the first three installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies, ...

RF-controlled robot design requires S parameters to model and simulate various electronic passive resistors, inductors, and capacitor circuits represented as two-port networks. Examples demonstrating ...

This low-cost AM transmitter is tunable from 10 to 15 MHz with the help of ½J gang condenser VC1, which determines the carrier frequency of the amplitude modulation transmitter in conjunction with ...
