To test the module, first of all, point any NEC-protocol remote control toward the infrared receiver (infrared eye) of the module and press any key of the remote control handset. If the module is okay ...

This module uses a PIC12F microcontroller to take the signal input and translate it back into infrared. [Peter]’s system can be set up as a single receiver, and single transmitter, single ...

If your up for starting a quick little project, Hardware Secrets can show you how to build your own IR transmitter for the PC. As the article clip states, if you can use a solder iron, you can ...

This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

These ideas are identical to concepts used in cell phones and Wi-Fi. Initially we build a transmitter and receiver to communicate between Arduinos using Morse code sent by pulses of light waves. Next, ...

RF module does have some limitations which is it can only provide one way data transfer. Extra data can only be sent by transmitter to the receiver but not the other way around. This factor limits ...

Claiming to provide highly stable operation in a 10% smaller package compared to similar devices, the FMRTF3 transmitter and FMRRF1 receiver modules require no external components. They operate on ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or ...

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. 2. Here’s the receiver ...
