The purpose of the remote dimmer control circuit TV (Philips RC5 code) 220V lamp with brightness adjustment can be made. Increase and decrease +10, -10 and +1, -1 as is done in two ways. Circuit PIC16F628, and 4N35 MOC3021’ve used. @ Melih. While the project design involved a great many thanks to ETE evening. PIC16F628…
Serve to control the 128×64 graphic LCD with a preview of the contents of the array and menu graphics. The heart of the controller is Atmega 128 CPU for communication with the PC corresponds to the FTDI FT232BM. As today is the prototype implemented a very simple menu on the display + 3-button keypad. A…
Almost all modern sound cards are no longer integrated audio amplifier. For all those who have no external active speakers on the PC operating system, is This small stereo amplifier with a sine wave output power of 2 x 3.5 W conceived. Thus, any passive boxes with impedance between 4 ohm and 16 ohm directly…
IRF4905 MOSFET with very few elements 5 amp current control, current limiting circuit input voltage line connected on 8 + .40 volts DC current through this circuit is limited to 5 amps 5 amp current draw on the output voltage drops Even when loading medium capacitors in the range of some 1000 F µ Einschaltmoment…
A friend I made for 2x30W amp circuit to say the least, this work had to take care: D tda7377 was the best choice integrated single-source supply is working with 14 volt 2 × 20 watts of power can give max supply voltage of 18 volts DC passive elements very least three capacitors first resistance…
Converter from USB to LPT parallel port (25 pin SubD receptacle) with hardware virtualization at input/output instruction level Supports all parallel port modes named SPP, EPP and ECP, 16 Byte FIFO depth USB Low Speed (1.5 Mbit/s signaling; 1 kByte/s for input/output instructions) Supports USB suspend mode with reduced power consumption Full open-source, even for…
Supply most laboratory power supplies maximum output current of 2 A to 3 A (Depending on model), while the output voltages usually up to 20 V or are more adjustable. Is, for example, at 6 V a current of 4 A needed is the power supply no longer able to deliver them, although the required…
L298 L297 Motor Driver Robot, cnc, or you could use different control projects prepared with sprint layout PCB and the SPLA have been prepared with schema file. L298 is an integrated H-bridge driver. Bipolar stepper motors are designed for driving. Max 2A/Phas could flow. The output signal is applied to the input phase upgrade to…
The keyboard on the computer recording the transactions in the know Keyloger programs between two PC’s with this circuit you can do the same process as wireless Coding in C language prepared by a different project or my işetişi wireless data radio frequency control on the computer can be useful for people interested in Receiver…
Tone control is a nice application that consists of 3 parts, vu-meters, two-channel amplifier and two from the Input Selector integrated circuit TDA1514 used in integrated information 50w max output power Amplifier can be connected to two devices at the CH1 and CH2 input signal can be selected with the button that selects the circuit…
