AC dimmer using Arduino

AC dimmer using Arduino

AC dimmer  What is dimmer Dimmer is a circuit that control the voltage level by changing its waveform and gives output minimum or less than the input and make the brightness of light dim or change the speed of fan as required level.  AC dimmer is mainly two types, one is manually and second is automatic. In manually dimmer circuit […]

What is Fusible resistor

What is Fusible resistor

Fusible  Resistor or Fuse Resistor Fusible resistor is a special type of resistor made for the purpose of protection of any circuit . This resistor made by such material that have characteristic of fusing without flames or without excess heat generation when current load jumps suddenly more than required. When you see normally in any circuit this looks roughen and […]

Turbo bass circuit

Turbo bass circuit

This bass booster circuit is made using the quad op-amp ic LM324. This op-amp ic has  4 operational amplifier, but in this circuit only 2 op-amp is used. This circuit provide Low pass filter of input audio which produce a Low frequency of input and high frequency is blocked . Connect the circuit as the given diagram as below . […]

Semiconductor device numbering system

Transistor identification guide  How to identify a diode and its specification Each Semiconductor devices have a special numbering coding as per specification of that components. All Components have a particular symbolic numbering with Alphanumeric coding for represents their characteristics of material and other parameters. There are international numbering system for all semiconductor devices and components . The 1st letter of […]

LOGIC GATES

LOGIC GATES

  LOGIC GATES Logic gates are the basic building elements of any digital systems or circuits. The name Logic gate is derived from the sense of the making decisions ability of such a device, and after making decisions it produce one output result. We  can say that Logic gates are the fundamental building blocks of any digital circuits or digital […]
