Questions tagged [remote-control]

For questions related to the remote control of devices and the design of remote controls.

"remote" means distant, and remote-controlling means "control" something from a distance, without any electrical or physical contact to the device-to-control. (Quite similar to Wireless... i.e. no-wire. However the term Wireless transmission commonly used for radio-waves).

However, a remote-control system not necessarily use radio-wave-signal, it can use infrared(IR)-signal, or many-other type of signal.

Just like wireless-radio-transmission, remote-controling also have similar steps, like 1. Input on remote controller by user-> 2. Signal-generation -> 3. Signal radiation or transmission -> 4. Sensing the signal on the remote controlled gadget -> 5. decode the signal -> action or required-change on machine.

Choosing voltage regulator and battery for a compact RF remote control (transmitter)

I'm designing a remote control based on a TWS-DS-6 433.92MHz transmitter and I wanted it to be really compact and energy efficient. I plan to have an ATtiny85 controlling the transmitter and use VitualWire software library to send data to the…

Cause of difference in theoretical and experimental values of RC time constants

What accounts for the slight difference in the theoretical and experimental values of the time constant in a simple RC filter? The slight difference was just (.5*10^-4) seconds

Remote Start for my Dust Extractor

I have a 1.5kW 220VAC 1 Phase dust extractor. It's controlled by what looks like a DOL switch KJD17B/5T (so I assume the 5th terminal is an overload). KJD17B Datasheet Wiring diagram on duct collector: From what I can see it's DP/ST and has L/N In…

How is the remote control working

I am for the first year in electrical engineering so sorry for this question but i couldn't test it by my own. One of my lecturers said that the remote control of a TV saves the channel we choose, and that when we press the "last channel" button,…

Issue with wiring eMylo remote control switch

My eMylo switch has five electric sockets (which can be wired.) The wiring diagram shows that the input positive (anode - the red wire from the 12 DC power) must be wired to the most right socket of the switch, the input negative (cathode - the…

"Inverse rc" impulse response circuit

I am a digital design engineer and am struggling to come up with an analog circuit that could produce an (RC) curve like below. It does not have to be an exact RC curve. Something that comes close would do perfectly fine. Thanks, Robert

Can I connect a button on my motorcycle to the main button on a garage door remote?

I want to connect one of the existing switches (high-beam flash, or turn signal middle push button, or horn, or pretty much any other switch/button) on my motorcycle to the main switch of a garage door opener, so once I am home and hit that switch…

Making my own 38kHz remote

The issue I am having is it appears many modern remotes don't have a 38kHz carrier frequency for the infrared signal. I would get inconsistent readings using an TSOP 1738. Since the remotes you can buy as a kit are always cheap and ugly, how hard is…

How to hook digital input to remote control buttons?

For a DIY project I would like to adapt a remote (RF) control to accept digital signals from MCU. I am not quite sure how the buttons in question work: Are they normal buttons which make near 0 ohm connection or something advanced (it's part of the…

Charging an RC circuit with two different Voltages?

I am giving step input voltages of value 10V and 5V to an RC circuit. Will it take equal time to charge the capacitor to its's final value? OR 5v will take more time to charge and 10v will take less time for charging the capacitor to it's final…

Can any remote be used with an RC car?

I just bought this awesome H2 Hummer RC for $2 at a garage sale (the battery alone that was inside is worth about $100.). The motor works fine and the car is in excellent shape but it did not come with a remote to control the car. Is it possible to…

Is a toy's remote controller interchangeable?

This Christmas I'm buying a couple people remote controlled quadcopters. Then it hits me. Is there a possibility that the different remote controllers will crosstalk and wind up controlling a robot that it is not meant to control? How do electronic…
