Arduino Frequency Coutner

http://circuitdigest.com

Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of signal generated by a clock or a counter or a timer. We can use oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency but all these devices are costly and are not for everyone.

Voltage Doubler Circuit

http://circuitdigest.com

Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 5v voltage, we will get 10 volt at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the quick, easy and practical solution to double the voltage, using 555 timer IC.

Interlocked Monostable Timers

http://home.cogeco.ca

This is done by connecting the OUTPUT of each timer to the TRIGGER of the other through a diode and placing a resistor in the trigger circuit. The resistor limits the current from the opposite timers output when the trigger is closed on the stopped timer.

Astable Mode of 555 Timer IC

http://www.learnabout-electronics.org

If an oscillator of a particular frequency and mark to space ratio is required, the method would be to calculate periodic time from the required frequency and the discharge time and charge time using the formulae for tD and tC described in Oscillators Module 4.3. To do this, some component details will be needed.
