Using Push Button Switch with Atmega32 and Atmel Studio

This tutorial is meant for beginners in the field of Atmel AVR programming. I hope that you already read my first tutorial Blinking LED using Atmega32 and Atmel Studio. In most of the embedded electronic projects you may want to use a push button switch to give user inputs to the microcontroller. To use a push button switch with a microcontroller, first you should configure the corresponding pin as input. T ...

OH HAI! on Windows 10 IoT Core

Story Oh, Hai Hai ('hi') is an integration point for several stand alone smart home technologies.  Hai runs on the Raspberry Pi and can be adapted to optimize electricity consumption (lighting/HVAC) and water usage (irrigation/rain collection) in a number of ways. Hai was originally envisioned for any Pi running Raspbian OS, but is also being ported over to utilize the new Windows IoT Core on a Raspberry Pi ...

Programming ATtiny85 with Arduino Uno

Story I am working on a project which requires reading multiple sensor data on different locations. These require only few PWM pins so using multiple Arduino Uno would be expensive and unnecessary. So I decided to use ATtiny85 microcontroller in place of Arduino Uno development boards.ATtiny85 is a cheap and powerful alternate when u don't need too many PWM pins. Since ATtiny85 is just a microcontroller we ...

Atmel SAMD21G Sensor Board

Mike Rankin created this tiny sensor board with an ARM Cortex M0+ microcontroller and OLED display: 0miker0’s Blog: SAMD21G Sensor Board It’s pretty tiny so a 4 layer board made the whole job easier. The top and bottom are pretty much dedicated for components, layer1 are tracks and power traces, layer2 is a ground plane. Mixing up an internal plane and routing layer was interesting. The hardware consists of ...

Atmel AVR ISP Microcontroller Programmer Project

One of the frustrating part in learning AVR microcontroller for the beginners is the AVR microcontroller programmer. The question is how to program my AVR mircrocontroller; actually if you googling on the internet and search for AVR ISP Programmer there are plenty information; start from simply using your PC parallel port to the sophisticated Atmel owned AVRISP mkII programmer. This will rise another questi ...

Building the I2C Smart DC Motor Controller with Atmel AVR Microcontroller – Part 1

The idea of building my own I2C (read as I square C) smart DC motor controller is came to me when I was learning and playing together with my son on his LEGO® MINDSTORM® NXT 2.0 about a year ago. The NXT sophisticated controller also called NXT Intelligent Brick is powered by Atmel 32-bit ARM7 AT91SAM7S256 microcontroller and communicating with Atmel 8-bit AVR ATmega48 acting as a co-microcontroller using I ...

Telepresence Robot using Microchip PIC16F1829 and Atmel AVR ATmega168 I2C Smart DC Motor Controller Microcontroller – Part 2

The I2C (read as I square C) smart DC motor controller is designed using the Atmel 8-bit AVR Atmega168 microcontroller and configured to act as the I2C slave device where it could be controlled by other microcontroller or microprocessor through the I2C SDA (serial data) and SCL (serial clock) interface. In the first part we have accomplished a basic DC motor controller tasks i.e. differential steering and s ...
