73 MHz Hallogene Lamp Radio-Controlled circuit
This circuit is a 73 MHz Hallogene Lamp Radio-Controlled. The purpose of it is to control the power state of a hallogene lamp by a remote control. When we press the push botton of the remonte control, the power state of the lamp will be changed, so, if the lamp was turned on, it will turned off and if it was turned on, it will turned off. If we pr
Infra Red Remote Control
This circuit is the result of Andy Collinson research. He has used a photodiode, SFH2030 as an infra red sensor. A MOSFET opamp, CA3140 is used in the differential mode to amplify the pulses of current from the photodiode. LED1 is an ordinary coloured led which will light when IR radiation is being received. The output of the opamp, pin 6 may be c

Core Remote Control Unit
If the unit has been sitting idle for a long period time (dead AAA batteries) and you see only garbage on the display or the unit doesn`t operate, the first item required is probably a new internal lithium battery. Although the unit was exceptional for its day, a major flaw with the unit was allowing the firmware to be lost if this battery ever...
IR Remote Control Receiver
With many audio systems consisting of separate units, you`ll oftennd that due to economic reasons only the amplifier has a remote control receiver module. The control signals are then sent to the other units using patch cables. The tuner and CD player, for example, won`t have a built-in receiver module. When the tuner from such a system is bou
IR Remote Control Tester
This small circuit is ideal for checking the basic operation of an infrared remote control unit. The circuit is based on the brilliantly simple idea of connecting a piezo buzzer directly to an IR receiver IC. This method is almost as simple as connecting a photodiode directly to the input of an oscilloscope, but has the advantage that no oscillosc
On-off Infrared Remote Control
Most homes today have at least a few infrared remote controls, whether they be for the television, the video recorder, the stereo, etc. Despite that fact, who among us has not cursed the light that remained lit after we just sat down in a comfortable chair to watch a good film This project proposes to solve that problem thanks to its original app
RC (Remote Control) Switch
It is sometimes necessary for an RC (remote control) model to contain some kind of switching functionality. Some things that come to mind are lights on a model boat, or the folding away of the undercarriage of an aeroplane, etc. A standard solution employs a servo, which then actually operates the switch. Separate modules are also available, which
Remote Control Mains Switch
As the only electronics engineer in my family and circle of friends, it is sometimes not possible to evade an appeal for help.

SIMPLE RF REMOTE CONTROL CIRCUIT
The Remote Controlling Circuit
The design of this project depends on the sensors. The control module and the robot both contain sensors. The computer, in turn, analyzes the signals to make the appropriate output actions. As previously mentioned, the potentiometers are the sensors on the control unit. They send the signal to the computer that interprets the data. However, the co
GSM Remote Control 2 IN and 2 OUT Part 2 Schematic
The entire control is handled by a Microchip PIC18F46K20-I/PT microcontroller, programmed with a firmware that controls the GSM/GPRS module`s activity, reads the logic condition of the two opto-isolated inputs and sends commands to the two relays in the device. Having said that, let`s take a better look at the electrical scheme: power is supplied
GSM Remote Control Gate Control Schematic
Power is supplied by continuous voltage, not always stabilized (applied to PWR + and -) at a value between 5 and 32V; such voltage is filtered at the bottom by the diode protecting against polarity inversion (D1) through condensers C1 and C2. Fuse F1 enables us to protect both thecircuit and the power source in case of a short circuit in the...
GSM Remote Control MotherBoard Schematic
The entire remote control is handled by a PIC that controls the GSM/GPRS module`s activity, reads the room temperature through a Dallas DS1820 smart probe, controls the logical state of two opto-isolated inputs, and gives commands to the two relays. In addition, the circuit is equipped with a DTMF decoder whose purpose it is to identify the...
GSM Remote Control Module
This GSM Mobile is used for our Remote Control (for example Gate Control, Temperature Control . ). We use the word module` because, unlike what we did in ourremote control projects, this time around the mobile phone is not mounted on a printed board, but rather on a small auxiliary board which is then inserted in a connector specifically created
GSM Remote Control Temperature Control Schematic
The full GSM thermostat is managed by a Microchip PIC18F46K20-I/PT microcontroller, programmed with a firmware that controls the temperature and takes care of the communication with the GSM module which is the component named GSM; this is, in fact the small board hosting the cell, so the pins` numbers refer to the used pin-strips` contacts. The fi
Remote-controlled fiber-optic Ceiling Light with Arduino
A wood table with many holes with different diameters that house the optical fibers. The size of the ceiling lamp (90 cmx 60 cm) did not allow me to use a single bundle of fibers and this is the reason of the two beams I used, each of which comes with a LEDs illuminator as shown: The schematic with Arduino and its control circuit is shown in the...
TiDiGino the Arduino-based GSM remote control
Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. The remote control is easier, thanks to the availability of several libraries that allow you to do anything to the Arduino microprocessor; if

Atari Joystick Wired Remote Control for Robots
The simplest solution for implementing joystick control for a robot would be to program the actions in software in a microcontroller. But, since many readers prefer off-the-shelf parts, this circuit is going to be made with diodes, resistors, transistors, and one FAN8200 motor driver chip. The downside is that the circuit is more complex. D10: A S

Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...
