Fixed resistors In Sinhala

Fixed resistors පිළිබඳ සරල සිංහලෙන් දැනගමු!

Resistance is the opposition for the current flow.
Resistance is measured in ohms (?)
Resistance can be measured from the multimeter directly.

Steps :
Set the multimeter to the resistance range. 
Connect the resistor to the multimeter leads.
Take the reading on the display.
Resistance of the resistor can also be calculated using the colour bands printed on the surface of the resistor:

Steps :
Observe the 1st 3 color bands of the resistor (starting from the opposite end to silver or gold color band)
Each colour represents a number.
Black-0
Brown-1
Red-2
Orange-3
Yellow-4
Green-5
Blue-6
Violet-7
Gray-8
White-9
Combining the numbers we can calculate the resistance value as shown in the photo.
The 4th color band gives the tolerance of the resistor.
Silver represents a tolerance of +/-10%
Gold represents a tolerance of +/-5%

How To Blink a LED With Arduino In Sinhala  Arduino මුලධර්ම භාවිතයෙන් පහසුවෙන් LED බල්බයක් නිවී නිවී දැල්වෙන අවස්ථාව උදා වීම සහ එමගින් ඉතා සාර්ථක ආලෝක රටාවක් සැකසා ගැනීම වනතෙක් සියළු පියවර අන්තර්ගතව ඔබ වෙත  ඉදිරිපත් කරන  වීඩියෝවයි මේ! In this video we need;  Output pins of the Ardunio board has the ability to give around 20 mA per I/O pin. This 20 mA is more than enough to switch on an LED. Rather than using the full current we are to limit the current by using a resistor in series. A good resistor value is 330 ohms. (use can use any resistor between 150 – 330 ohms) Steps : Connect the Arduino board to the computer via the USB cable. Open up Arduino IDE. Select the correct COM Port. Select the correct Board . Type the code and Upload. Code and Tutorial PDF Zip - https://drive.google.com/open?id=0B-xkwb9ASKxXWmhSOTdFTjlGTDQ

Fixed 5V regulator Using 7805 In Sinhala

Image
5V Regulator එකක් භාවිතා කර Phone Charger එකක් නිර්මාණය කරමු! The 78xx is a series of fixed-voltage integrated-circuit voltage  regulators designed for a wide range of applications. The Ic can handle upto about 1.5A of current. Working temperature 0 – 125 º Celsius Examples : -7805 (5v regulator Ic)  -7812 (12v regulator Ic) Properties : -Thermal shutdown features. -Overload current limiting features. -High power dissipation capability. -Bias current (~1–10mA). Part List: 7805 IC 0.33 μF 0.1 μF When the circuit is set you can successfully obtain 5v output from a varying dc voltage source (7-25V). The capacitors helps to stabilize and filter noise of the input.  Applications: Powering a micro controller Making a mobile phone charger 7805 regulators are cheap and efficient.

Dark Sensitive Circuit With C828 Transistor In Sinhala

Image
අදුරට සංවේදී පරිපටයක් සකස් කර ගන්නා ආකාරය සරල සිංහලෙන්. Dark sensitive circuits have a range of applications such as turning on lights when the light level falls below a certain threshold.In our circuit this threshold is changed by using a variable resistor which can be turned to fine tune the circuit. The circuit consists of the following components: C828 transistor x1 7805 voltage regulator x1 1 kilo ohms resistor x1 LDR x1 LED x1 100 kilo ohms variable resistor.  The base current of the transistor is controlled by the potentiometer.In very low light conditions the ldr will have a very high resistance and in high light conditions the ldr will have a low resistance.In the dark condition less current will flow through the ldr so more current passes through the base of the transistor causing a high current flow through the led via the collector pin of the transistor causing the led to light up but in high light condtions the ldr will have a low resistance there for most...
