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 [...]

Using Push Button Switch with Arduino Uno

In this tutorial you will learn how to read the status of a digital pin of Arduino. I hope that you already go through our first tutorial, Getting Started with Arduino Uno – LED Blinking. In this example, a push button switch and an LED is connected to Arduino Uno. When we press the switch, LED will glow for 3 seconds. A pin is configured as Input Pin to connect switch and another pin is configured as Output Pin [...]

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 [...]

Arduino – Development Board For Beginners

Arduino Uno R3 Arduino is a development board based on Atmel Microcontroller introduced in 2005. It is intended for beginners in the field of electronics. This can take inputs from different switches, sensors and can given output to surroundings through light, sound, motion etc. This is the most convenient method for computer based students to develop electronic projects with basic knowledge in electronics. It is an open source system which is flexible and is easy to use. Arduino has its [...]

UM66 Melody Generator – First Step for Electronics Hobbyists

UM66 UM66 is a melody generating IC commonly used in calling bell, phone, toys, musical bell in doors, home security alarm systems, burglar alarms etc. It is a three pin IC looks like a transistor. Its first pin is ground, second is VCC and the third is the melody output. Supply voltage that can be given to the IC is in the range of 1.5V- 4.5V. These are CMOS ICs and have very small power consumption. Melody generator will reset when [...]
