Build Your Own Microcontroller Based PID Control Line Follower Robot (LFR) – Second Part

One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor (Build Your Own Transistor Based Mobile Line Follower Robot – First Part) and enhance it to the programmable version that use microcontroller as the brain for controlling the robot. The reason of using the microcontroller for the Lin ...

Darby’s not dead.

Hardware components: Particle Spark Core × 1 atmega168 × 1 pn532 breakout board/ adafruit × 1 Story In the future there is a bar where all the dead punk rockers hang out. They are each given a MiFare classic card programmed with their name and 666 credits. This is the device the bartender uses to keep track of their tab. This project uses an atmega168 to control a pn532 breakout board to write cards as well ...

AVR Twinkle Twinkle Using PWM Project

Would be interesting if we could make our microcontroller to sing for us not just beeping or blinking; this project is all about using the powerful AVR ATmega168 16-bit PWM feature to produce accurate musical notes such as playing the child’s favorite Twinkle-Twinkle Little Star song or we could say beeping with style. The principal we learned here could be applied to other AVR microcontroller families that ...

AVR LCD Thermometer Using ADC and PWM Project

Sometimes we need our microcontroller to interact with more human readable information. It will be better for us if we could make it display the words not just blinking the LED. Today most modern gadget such as mobile phone and PDA, use LCD (Liquid Crystal Display) for interacting with us. In this project we will learn how to use the 2×16 LCD for displaying the room’s temperature. Actually driving the LCD h ...

Using Serial Peripheral Interface (SPI) Master and Slave with Atmel AVR Microcontroller

Sometimes we need to extend or add more I/O ports to our microcontroller based project. Because usually we only have a limited I/O port left than the logical choice is to use the serial data transfer method; which usually only requires from one up to four ports for doing the data transfer. Currently there are few types of modern embedded system serial data transfer interface widely supported by most of the ...

Program an ATmega168/328 with codebender

If you want to use an inexpensive ATmega168 or ATmega328p for your project, but you want the simplicity of the arduino code and codebender, this tutorial will guide you through! A brand new ATmega microcontroller does not come preconfigured to use with Arduino code. So to use one of these you normally need a high cost ATMEL ISP programmer to burn the Arduino bootloader into your ATmega. Thankfully there is ...
