IC 4049 Square wave oscillator generator

We can bring the inverter CMOS digital IC is CD4049 Hex Inverting Buffer IC, to design the Square wave oscillator generator circuit diagram or Simple Pulse Generator circuits, to a lot circuit been simplified.
The circuit we use a little equipment, just add a resistor and capacitor are the only one,It uses less energy. The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less. The pulse generators can also produce a 50% duty cycle square wave. The ICs in the circuit number CD4069,TC4069,LM4069. The frequency determined by R1 and C1 is F = 1 / (1.39xRxC). The power supply used DC 3V-12Volt.

Led light running mixed using not gate

Many people would never suspect.IC is not Gates, frequency generator that? Will be deployed there? The rubber or how it works? This circuit will work to understand more easily.Because a simple circuit is simple.
This circuit, the circuit will run at the IC not gate, the circuit arranged as a sequence.Work is in the initial condition at pin 3 of IC1 / 1 to 0 volts, will cause the voltage at pin 2 of IC1 / 1 to 9 volts.And pin 15 of IC1 / 6 to 0 volts, the LED1-LED8 not lit.However, due to pressure from the pin 2 of IC1 / 1 is connected to R3, C3 to charge through the R3.To Pin 7 of IC1 / 3 to 9 volts.As a result, the voltage at Pin 6 to 0 volts, pin 10 of IC1 / 4 is 9 volts, the LED17-LED24 light.Because pin 6 of IC1 / 3 R3 is connected to the pin 5. Of IC1 / 2 to 0 volts, as a result, the voltage at pin 4 to 9 volts.And pin 12 of IC1 / 5 is 0 volts, LED9-LED16 it off.However, subsequent pressure on the leg 4 of IC1 / 1 to make pin 3 of IC1 / 1 to 9 volts.The next, LED1-LED8 light.
The order of the signal voltage at IC1 pin is pin 15, 12 and 10, respectively, were indefinitely.

IR Remote Control Extender by 4049

This is an improved IR remote control extender circuit. It has high noise immunity, is resistant to ambient and reflected light and has an increased range from remote control to the extender circuit of about 7 meters. It should work with any domestic apparatus that use 36-38kHz for the IR carrier frequency. Please note that this is NOT compatible with some satellite receivers that use 115KHz as a carrier frequency.
The main difference between this version and the previous circuit, is that this design uses a commercially available Infra Red module. This module, part number IR1 is available from Harrison Electronics in the UK. The IR module contains a built in photo diode, amplifier circuit and buffer and decoder. It is centerd on the common 38kHz carrier frequency that most IR controls use. The module removes most of the carrier allowing decoded pulses to pass to the appliance. Domestic TV’s and VCR’s use extra filtering is used to completely remove the carrier.
