Fig. 1: Image of an LED circuit on breadboard Image above shows a simple circuit that glows an LED when connected to power supply.. Connecting LED directly to the power supply will damage it, hence aresistance of suitable value must be connected in series for its proper operation. Following the standard color convention,red wire serves as…

Step 1: How to Use Multimeter Fig. 1: Image of a multimeter   As its name suggests, a multimeter measures various circuit parameters such as resistance, voltage, current, and capacitance. More precision over multimeter readings can be achieved by using a digital output.Measurements of different ranges are marked on the DMM. These are the maximum values of…

This tutorial will detail with testing PNP and NPN configured transistors using a multimeter. After reading this, you will be able to find out configuration of the device as well as find out its collector, emitter and base. Fig. 1: Image of a transistor  Step 1:Transistor Function on Multimeter. Fig. 2: Image showing Transistor function region in…

Step 1: Understanding the component Fig. 1: Image of an LED Light emitting diode (LED)is a small component used in almost every electronic device. Led has 2 terminals or legs. The bigger leg is the anode or positive terminal and shorter leg is cathode or negative terminal. But this method of identifying the leads will not…

Step 1: Understanding Diode Fig. 1: Image of a Diode Diode has two terminals Anode (+) and Cathode (-). Terminals can be identified by the shaded portion at the end of the diode. Terminal near the shaded portion is Cathode (-) and other one is anode (+). Diode can be tested with the help of Diode…

I am designing a circuit which can be controlled by  TV or AC remote. For that I have purchase TSOP1738  with few more components from market. And I assemble my circuit carefully, then also I am not getting the desire output. I again rechecked my assembled circuit with the circuit diagram and I don’t find…
