Questions tagged [remote-control]

Used to describe the act of (often wirelessly) controlling another system.

Forms of remote-control

Remote control can be separated in two categories: wired or wireless.

Remote control is different from remote communication in a way that the second device usually does not change the logic and that each signal usually represents an action rather than information.

(In consumer electronics, a remote control is the device to control a TV or set-top box. Also an RC-car is an (often radio) controlled miniature vehicle.)

Wired

A wired remote control system isn't all that different from a regular system. The increased length of wiring might bring in problems though. For long-distance wiring, interference and signal strength might become a real problem. The use of differential signals (RS-422, RS-485) in combination with quality (shielded) twisted pair cables should extend the maximum possible cable length. The use of internet might also be a solid option for wiring remote control systems, but you should be very wary of security risks (and even then, it's still a risk). High-risk applications are "never" connected to the internet.

Wireless

For setting up a wireless connection, there are several protocols/implementations around.

Such as: Bluetooth (HC-05/06), WiFi (Esp2866), Light/IR, radio signals or magnetics (limited range).

The security of wireless can also be a risk, since the signal could be intercepted/altered.

Directional

Some remote control applications are bi-directional, which means that there is no defined "master" or "slave" device. And that both the devices can control each other.

Tone() conflicts with IRremote library (multiple definition of `__vector_7')

I have just started with Arduino and C++ so I apologise if my question is very basic. I am trying to use tone() with a passive buzzer to create a sound while also using the IRremote library for a remote. However, whenever they are used together, it…

Is it possible to transmit using an NRF24L01+ without an Arduino?

I have two NRF24L01+ modules which are transceivers, but for my project I would like to send a very simple signal from one of these modules to the be read by the other. That would've been very simple if I had an Arduino on each side but due to power…

Wirelessly communicate between two Arduinos without router

I want to "connect" two Arduinos, without using wires. The range is ~0.2 miles (300 meters). Using Google, I saw too many options. The idea is to build something like a beacon, so the bandwidth can be small. I want to send 32 or 64 bits/second of…
