In many sectors, conventional keys are fast becoming obsolete, a development that has now reached the self-storage industry. Keep It Simple Storage (KISS), a U.S.-based provider of state-of-the-art solutions designed to simplify running self-storage facilities has transitioned from manual locks to fully automated and remote-controlled systems for secure locking. With the NFC-powered, battery-free smart lock…

With technological advancements in consumer electronics, nowadays almost every appliance in our home is remote controlled.Managing a different Remote for TV, AC, Fan, DVD, DTH, etc., is quite difficult. What if we could have only one remote capable of working as a dedicated remote for any appliance any time.Presented here is such a device based on Arduino that can act as Remote control for any appliance when needed. 

Basically, the Remote controls of Electronic Appliances be it TV, DVD, etc., work on IR communication principles. They transmit a code, in the form of IR pulses which is decoded by the reciever to carry out a specific operation. Each key has been assigned a specific code based on a certain standard protocol developed by the manufacturer.There are number of protocols that have been developed till the date by various manufacturers including Sony, Philips, etc. Some of common and widely used protocols are Sony SIRC, Philips RC5/RC6, NEC, etc. 

Controlling speed of AC motor is required in industries as well as in domestic use. In industries the required motion control is achieved by controlling speed of big and heavy AC motors. They use variable frequency drives (VFD) for speed control. In some other applications like fan, blowers, heaters etc another method for speed control is used that is phase angle control. By varying phase angle, the current supplied to motor can be varied. And by varying supplied current the speed of motor can be varied.In domestic application the phase angle control method is used. The best example is fan regulator. In domestic fan regulator DIAC and TRIAC are used to vary phase angle of fan motor. This is very easiest method to vary AC motor speed.  

Today we are controlling many appliances with the help of remote like AC, TV or music system. It often happen that remote stops working due to any reason (lowbattery or any button of remote becomes faulty). Therefore circuit describes below help you to test your remote to identify that appliance (TV, AC etc) has problem or your remote is not responding. Advantage of circuit- Based on single sensor and hence circuit consumes very less power. Almost every remote can be tested with the help of this circuit as operating frequency of sensor is 38 KHz.  High immunity against ambient light. With little modification in the circuit you can use it to control your home appliances with remote. 

 The circuit of this project utilises the RF module (Tx/Rx) for making a wireless remote, which could be used to drive an output from a distant place. RF module, as [[wysiwyg_imageupload::]]the name suggests, uses radio frequency to send signals. These signals are transmitted at a particular frequency and a baud rate. A receiver can receive these signals only if it is configured for that frequency.A four channel encoder/decoder pair has also been used in this system. The input signals, at the transmitter side, are taken through four switches while the outputs are monitored on a set of four LEDs corresponding to each input switch.The circuit can be used for designing Remote Appliance Control system. The outputs from the receiver can drive corresponding relays connected to any household appliance. Read more to find out how the circuit is assembled and made to work

In most of the industries for motion control AC motor or DC motor are used. To control the motion there is a need of either AC drive or DC drive. The basic functions of this drive are to give smooth start to motor change the direction, change the speed etc. Here I am demonstrating one such…

AC Drive is widely used and probably a vital controlling device in the field of industrial automation. Most of manufacturing industries, continuous production units, chemical industries, textiles miles, pharmaceutical industries are now equipped with most advance industrial automation and to control various AC motors the ultimate solution is AC Drive. What’s an AC Drive? AC Drive is actually…

This is the ultimate industrial remote control with 16 different channels and a very high range of more than 1 Km. Let us see the main features of this remote control system: Single chip DTMF based FM transmitter with 16 different channels. Programmable, multi functional, DTMF based FM receiver because of 89C51. Perfectly suits with…

Here to make a IR remote control I am using an ASIC codec chip ST12 where codec means coder decoder. That means same chip is used as encoder at transmitter side and as decoder at receiver side. It’s very nice chip and some of the major features of the chip are Encode / Decode on…

This is very interesting project. It is same as commercial available wireless FM bell but with sweet melody output. It can also be use to operate any AC/DC device from remote and safe place. The range of this remote control is up to 50 meter (basically this depends upon your FM transmitter if you use higher power…

Here to make a IR remote control I am using an ASIC codec chip ST12. Codec means coder+ decoder. That means same chip is used as encoder at transmitter side and as decoder at receiver side. It’s very nice chip and some of the major features of the chip are: Encode / Decode on single…

It’s multi channel IR remote control so you can perform not just single but so many functions with this remote control. Micro-controller 89C51 is used in receiver part so its programmable remote control. You can program it to perform specific task or for specific application. Some applications that I have developed are “Remote control for home appliances”,…

This device can be used to control (ON/OFF) eight high voltage electrical equipments with a remote control. The LEDs connected shows the status of the relays (ON or OFF). If one relay is ON then the corresponding LED will be ON otherwise it will be OFF. The remote control is shown in figure. The RED…
