Today we will make a Adjustable LED flasher-first potentiometer using Arduino. It is first time that we use it. First to use potentiometer on Arduino Arduino has the analog input pin (A0 to A5 for read any signals. When we apply voltage to potentiometer and to analog input pin Arduino. We can apply to control electornics appliance. When we rotate the potentiometer make a voltage across it change. The arduino can read this changing. As Figure 1 analog input pins and Power output pins that we use with the potentiometer. Figure 1 Analog input and Power output Parts you will …
Today we learn the simple simple Button Digital Input using Arduino it is very easy. The Arduino has Digital I/O PINs. Which “I/O” is Input and Output We used the output of Arduino to display the LEDs. Today we need to use the switches as digital input pins to get a various electrical signals to control the operation of the circuit as well. What is Digital? Digital is a kind of electrical signal. Which has work of only two states are: – HIGH or ON or “1” – LOW or OFF or “0” We bring this digital Go to the …
This is the easy 3 LED running circuit or LED Chaser using Arduino. We will learn code “int” to define the variable. -variable Is representatives of the various Let’s write code Sample one LED flasher. Which we’ve already made easiest it ——code Sample one LED flasher use int on Arduino int pin1 = 13; // to define the variable void setup() { pinMode (pin1, OUTPUT); // pin1 = 13 }void loop(){digitalWrite(pin1, HIGH);delay(1000);digitalWrite(pin1, LOW);delay (1000);} ++++++++++++ From the code above. We use “int” to define the variable: pin1 = 13 The number 13 is output of arduino use for LED In void …
Today we will make a 2 LED flasher using Arduino (UNO) Usual we use a transistors circuit to make two LED flasher. This we will study programing C code on Arduino. It is easy to learn. Step to step by Chayapol. Lets go! Figure 1 Define pictograms,easy to understand Figure 2 Set the diagram programing Figure 3 Put code in programing Then, we open the Arduino IDE software. Next,write the code below CODE void setup() { pinMode(13, OUTPUT); pinMode(12, OUTPUT);}void loop() { digitalWrite(13, HIGH); digitalWrite(12, LOW); delay(1000); digitalWrite(13, LOW); digitalWrite(12, HIGH); delay(1000);} Figure 4 programing on Arduino IDE And then, …
Today, let’s do a one LED flasher. Which we use the Arduino Software (IDE). Although, difficult to use, because the text mode. But it works completed, the most popular and free. Step by step as 9 years boy learning. 1. Define symbol that human understand “LED is ON” and “LED is OFF” Figure 1 2. However, since the LED changes from “ON” to “OFF” very quickly. The human can not see it. We need to delay the LED ON longer for 1 second Figure 2 3.We start with programing, add a delay and “LED is ON”. The system will always …
