Analog to Digital Conversion in ARDUINO

Analog to digital conversion module of ARDUINO UNO has 6 input ports. The number of the port varies with your ARDUINO model but the coding remains the same. The analog reading in the analog inputs are converted into corresponding 10bit(0-1023). ARDUINO developers have made such an option that you can print anything and see it on the Serial monitor. This example demonstrates analog input usage by reading an analog sensor on analog pin 0 and turning on and off a [...]

PWM using Arduino

Pulse Width Modulation : PWM using Arduino

PWM using Arduino Pulse Width Modulation or PWM is a method of Digital to Analog Conversion. It helps in delivering analog average voltage using digital pulses of variable pulse width. By controlling the on time and off time, we can generate an analog average voltage using the digital pulses. PWM has a wide range of application. It is used in DC motor speed control, Brightness control of LED lamps etc. Here in this simple experiment to understand the PWM working in ARDUINO, [...]

Arduino Uno R3

Arduino Uno

Arduino Uno R3 The Arduino Uno is the most popular one among other Arduino development boards. It is  based on the microcontroller ATmega328. The factor which make Arduino Uno differ from others is that it does not use FTDI USB-to-serial driver chip. Instead it uses a microcontroller Atmega16U2 (Atmega8U2 up to version R2) which is programmed as USB-to-serial converter. Its peripheral features includes 14 digital input/output pins (of which 6 can provide PWM outputs), 6 analog inputs, a 16MHz crystal oscillator, a [...]

16x2 Green Character LCD Module

Interfacing LCD with Arduino Uno

16×2 character LCD display is a very basic LCD module which is commonly used in electronic projects. 16×2 means it can display 2 rows of 16 characters (columns). Its other variants such as 16×1, 16×4 etc are also available. These LCDs are usually made using HD44870 compatible controllers. In this tutorial we will see how to interface a 16×2 Character LCD display with Arduino Uno development board. Arduino provides built in libraries for interfacing HD44870 compatible LCDs. 16×2 LCD Pin [...]
