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 to...

Using Push Button Switch – MPLAB XC8

Push Button Switch I hope that you already go through the first tutorial of MPLAB XC8, Getting Started with MPLAB XC8 - LED Blinking. In that tutorial we learn how to use an output pin by driving an LED. In this we will learn how to read an Input pin using a push button switch. We already seen that TRIS register is used to set direction of each IO pin, ie Input or Output and PORT register is used to read...

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 USB...

Getting Started with MPLAB XC8 Compiler – LED Blinking

In this tutorial we will learn How to Blink an LED with PIC Microcontroller using MPAB XC8 Compiler. Recently Microchip released a series of development tools including MPLAB X IDE and MPAB XC Compilers. MPLAB X IDE is a software that runs on a computer intended to develop applications for Microchip's Microcontrollers and Digital Signal Controllers. It can be used with Windows, Mac and Linux Operating Systems. It is called an Integrated Development Environment as it provides comprehensive facilities to...

Read Modify Write Problem with Mid-Range PIC Microcontrollers

RMW Problem with PIC 16F Family Microchip's mid-range PIC Microcontrollers use a sequence of operations : Read, Modify and Write to change output state of a pin. In certain circumstances RMW operations might cause unexpected behavior of outputs. You might have already experienced this issue and struggled with it as you can't find exact reason with microcontrollers unexpected behavior. Mid-Range PIC Microcontroller uses two registers, TRIS and PORT to control the direction and status of an IO pin respectively. When you try...
