For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio signal and a 40 kHz carrier signal, implemented using the ...

Conclusion and Key Takeaways To summarize what we’ve gone through making, we started with a mere 3D design, installed parts, programmed, and tested the Arduino Pistol-grip Transmitter with its ...

I found that we could get the radio to reach the length of a 60ft bowling alley, but it worked best with one long range version as the receiver, and a standard module for transmitting.

Figure 1 shows the transmitter based on the microcontroller PIC16F1619. Pushbuttons PB1 thru PB4 are enabled to control four relays in the receiver module in Figure 2.

The HX1 from Radiometrix is a narrow band VHF radio transmitter module designed for use in various data-transfer applications. When used in conjunction with the matching RX1, BiM1R, or CVR1 receiver ...
