In this article I have explained about a peak detector circuit, its working principle and how to implement it in clap operated circuits for illuminating an LED in response to clap sounds. What is Peak Detector A peak detector is a circuit which holds maximum amplitude value of a signal. If a signal varies rapidly […]
Newly Updated Circuit Projects:
High Voltage Constant Current Source Circuit
The presented circuit offers an adjustable constant current source capable of reaching up to 60mA, operating at voltages as high as 350V. Circuit Description The input stage, consisting of resistor R1 and zener diode ZD1, delivers 8V to the regulator (a 7805), maintaining this voltage relative to its reference line. This voltage level ensures sufficient […]
Mains AC Home Protector Circuit
This simple mains 220 V, 110 V AC voltage home protector circuit will protect all the mains operated appliances of your home from high and low voltage situations and also from sudden voltage surge. The circuit can be used with 220 V AC inputs and also with 110 V AC inputs. The circuit will basically […]
LM35 IC Temperature Controller Circuit with Push Button
In this post I have explained a simple yet very accurate temperature controller circuit using IC LM35, featuring an automatic cut off with a push button latch. LM35 is a precision temperature sensor IC, which can be effectively used for detecting temperature differences accurately. For more details regarding this IC you can refer to this […]
Adjustable Voltage Regulator Circuit using LM324 IC with Over Current Protection
In this post I have explained how a single LM324 IC can be used to create an adjustable voltage regulator circuit with overload and over current protections. Basic Working A basic IC LM324 quad operational amplifier regulates an unregulated 28-volt input source to approximately ±0.02%, resulting in a 1 amp 0 to -20 V supply. The […]
How to Use TTP223 Capacitive Touch Switch Module [Pinouts Explained]
In this article I have explained how to connect and use the TTP223 capacitive touch switch module. These modules work using 2.5V to 5V. They are all pre-debounced, all you need is to provide the DC supply across the VC and GND terminals, and you get an output in the middle. So it is really […]
