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.... -
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.... -
Installing a small dash mounted 2 speed fan in my motorhome. What`s the best way Use your 1 channel and then find a relay or use the 4 channel and use the seperate wires [1 low spd. &1 high spd ] Any other lideas Would it hurt the unit if it were placed in.... -
This is a very easy circuit that every one could make and have fun. This project popped out of nowhere, one day that i was trying to control the TV from the serial port of the computer. It took me no more than a few minutes to understand the simple method.... -

I usually can`t hear the doorbell when I`m in the basement. This project describes how to add an inexpensive remote doorbell to your existing household doorbell. My doorbell runs off of a 24VAC transformer that is live all the time. Someone presses the.... -
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,.... -
The laser-pointer detection circuitry is able to determine when a laser light is aimed at a particular photosensor. If the laser is aimed at the top sensor, the comparator chip outputs on . If the laser is aimed at the bottom sensor, the comparator chip.... -
IR remote control for my Nikon DSLR camera. Not that I absolutely need one, surely I don`t need it bad enough to get one for about ‚¬30 or ‚¬40 from e-bay. However it would make a nice little in-between project. Big Mike explains the very easy protocol used.... -
A schematic diagram of the remote-control receiver is shown. The heart of the circuit is IC1, a PIC16C54 8-bit CMOS manufactured by Microchip. The microcontroller stores its data in IC2, a 93LC46 1-kbit serial EEPROM (electrically erasable programmable.... -
Starting from today I will try to post interesting Arduino projects from around the web. I am novice in this domain but I am giving my best to fully understant it. I must say from the begining that the projects are not developed by me and I will link the.... -
Is infrared emission circuit diagram. NE555 circuit generates a 40kHz pulse which is sent by the infrared emission control SE303 after beingamplified by VT. (b) is remote receiver and infrared dimming circuit composed of the KA2184. LS7232 is an integrated.... -
As shown in the diagram above, it is a radio remote control dimmer circuit. The radio remote control dimmer circuit adopts micro radio transmit/receive module and light modulation ASIC. So the circuit is concise and easy to produce. It works reliably. And.... -
The circuit is not only used for the latch output, but also for non - latched output, SB is control switch. When SB and VDD are turned on, it is in the latch output state, then the sixteen output ends are out control of Io output state; when SB and Io output.... -
HS101/HS201 are a pair of tiny radio transceiver components. The working frequency is 280MHz. It is suitable for digital signal transmission. The control distance is 30 ~ 100m. All the components including the antenna are packaged in one. It is easy to use..... -
The circuit uses the long-wave wireless transceiver T630/T631, controlled 6-channel load. The features are low-power, high anti-interference ability and simple structure etc.... -
TDC1808/TDC1809 is a pair of wireless remote control transmitter and receiver component. They use an internal antenna, transmitting digital signals or analog signals. It is suitable for a variety of wireless remote control device. The features are small.... -
Figure (a) is the infrared emission circuit that composed of 12 the keyboard and S2559. Figure (b)shows DTMF decoder circuit and channel control circuit composedof the MT8870. Figure (c) is the voltage amplifier circuit composed of two-op ampLM358.... -
The DTMF codec is the abbreviation of the dual-tone multi-frequency codec. The multiple-channel infrared remote control switch circuit which is composed of the DTMF is as shown in the figure. It is composed of the infrared remote control signal emitter, the....
