In the transmitter we have connected a push button with a resistor in series and, for the receiver we have connected a LED on the Data line, and both the circuits are powered by a 3.7V lithium battery ...

433 MHz (or 315 MHz) RF transmitter; 433 MHz (or 315 MHz) RF receiver; Sensors Ambient Light Sensor (BH1750) Temperature & Humidity sensor (SHTC3) USB – 1x USB Type-C port for power, data ... The ESP ...

This robot can be controlled from the terminal window of your computer. You can see a manilla-colored board mounted between the wheels. This is the RF receiver which has quite a long antenna that w… ...

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals.

The RF transmitter and receiver units are the two main components of the system. In this configuration, RF signals including information on the speed limit are broadcast by the transmitter unit, which ...
