Knight Rider Circuit with Arduino In Sinhala

 පහසුවෙන් Knight rider circuit එකක් සාදා ගන්නා අයුරු සරල සිංහල බසින්!

The digital pins of the Arduino can be used to power the led’s of this circuit
To limit the current flowing through the LED’s we use a resistor (150 -330 ?) connected series with the ground pin of the Arduino board.

Part list :
150-330 ? resistor x 1
Leds x 10
Arduino board x 1
Jumper wires
Bread board x 1

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.

Have fun by changing the delays.
Try – delay(100);

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 .

Fixed Resistors.        Fixed resistors පිළිබඳ සරල සිංහලෙන් දැනගමු! • Resistance is the opposition for the current flow. • Resistance is measured in ohms ( Ω ) • Fixed resistors have a fix value of resistance. • Circuit Symbols:    • Physical appearance of the resistor :  • Resistance can be measured directly  multimeter   . 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 1 st 3 color bands of the resistor (starting from the opposite end to silver or gold color band) ´ Each colour represents a number. ´ Combining the numbers we can calculate the resistance value. Example 1 : Example 2 : ´ The 4 th color band gives the tolerance of the resistor -Silver represents a tolerance o

How To Make a 0-12V Variable Power Supply In Sinhala | Part 02 Expanding the setup to a 0-12V variable power supply. We have already completed the 12V fixed powersupply tutorial vide so if you havent watched it first watch it and continue. By now we have completed the project upto a 12V fixed power supply as our next step we are to make the power supply variable. Additional Components Required: D400 x1 2N3055 x1 100kO variable resistor 1kO  Determining the pins of the d400 transistor is very straight forward but it can be tricky in the case of 2n3055. Refer the pdf for the pin configuration of the D400 transistor: 2N3055 : According to the data sheet the metal casing is the collector of the transistor. The problem is identifying the base and the emitter of the transistor. Steps: Put the multimeter to the diode mode. Connect the probes of the multimeter to the two leads of the transistor. If there is a reading on the multimeter then the positive probe is the ba
