RGB VU meter circuit TL072 Op-amp based on the environment in the sound with a microphone and detects the volume according to the RGB LED strip in different colors of light gives the LED strip on the 15 LEDs There TL072 output the transistor power of increasing the longer LED strip can be connected either…
Light, dark Switch circuit operation to circuit is located on the DipSwitch 5 number must be open. 1 and 2, 3 and 4 are closed while the circuit connected to the relay output device the light key (bright environments. If the device stops the dark environment.) It is used in. 1 and 2, 3 and…
555 timing IC made ??with a simple circuit than the number 2 pin trigger tip 220nF capacitor out according to the signal pin 3 of the output is rectified and the relay goes to the relay is energized contacts connected device opens or by connection closes two different modes can be 22UF 470k resistor and…
Timing has an integrated circuit made ??with N555 hundreds of years in the market all the electronic equipment in the shop a popular integrated See here for a detailed knowledge of Turkish. Circuit as musical notes can give a voice to the series resistance values ??button is pressed, left to right according to the RE,…
Cooler temperatures above by to run the fan I used a circuit test ready while we wanted to share a circuit LM358 op amp pointed at the board integrated output N channel mosfet (IRF540, 50N06 or IRFZ44) used 10k NTC temperature according to the output gives the work the threshold on the circuit 25k potentiometer…
Spy circuit consists of 3 sections there are about 30 pieces transmitter circuit is more complex, but in most circuits modified for reinforcement, additions fm transmitter varieties has been described Market located in the library known as the FM BUG popular video circuit operation note All circuits should be used for experimental purposes only and…
There are 3 USB converter circuits CP2102 USB communication as in the isolation section of the ISO7221 standard is being used. USB/RS232 adapters isolated TTL (RX-TX), isolated USB/RS485 adapter (+ max13488) usb1wir isolated adapter (+ DS280) All prepared with the USB adapter KiCAD source of PCBs, in addition to the schema files are picture. Psi…
LED lamp projects a similar application in this circuit LED strip groups directly 220v rectified operated sufficiently strip LEDs connected in series for voltage limitation does not need previous post as mentioned in 220v directly into direct use is not healthy but commercially using a bit in the lifetime depends on the condition, of course,…
Previously I shared 40 led vu meter circuit using Audio Spectrum Analyzer, Spectrum Analyzer circuit 10 channels (32Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz, 64Hz, 125Hz, 250Hz, 500Hz) on a total of 400 LED’s Spectrum Analyzer circuit 12v DC voltage works with all LEDs illuminated power draws 7.5 amps LM324 op amp used for all integrated…
VU meter circuit LM324 op amp based on this circuit a lot of books on the site saw ready vu meter integrated when there is much interest repellent, but this app is also 40 LEDs use and eagle prepared by the PCB drawing the lack of work is changing writers the same circuit 2 have…
