This example code and simple wiring demonstrated how to setup an AVR ATtiny85 processor to react to external interrupts. Whenever the voltage changes on the chosen input pin (pin 6 / PB1), it executes the interrupt service routine (ISR), checks the current voltage, and sets the output pin (pin 3 / PB4) to match. This […]

A while back, I posted up a quick and dirty “el cheapo” method of getting started programming the Atmel AVR series chips:Â Ghetto Programmer (version 1.0) Since then, I’ve vamped, re-vamped, and otherwise improved my setup. Thought it’d be nice to document it. The goal was to get a flexible, compact, portable, use-anywhere, AVR-based microcontroller prototyping

This is a tutorial for programming the ATtiny chip. This tutorial will be more in depth than most. I will give you every step and tell you the things nobody told me when I first started programming ATtiny. Things You’ll Need – Arduino Uno( Can be done with other boards but I will be using

For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC)Â and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude). I’d like to share

Lithophanes are artistic creations on ultra-thin translucent porcelain that is visible only when backlit with a light source. They are etched or modeled artworks made by a 2D image. The 2D image is first processed to make its gray-scale representation, and then, depending on the color, it is then converted to a calculated 3D printed height.

I have seen RGB mood lights using Arduino, PIC, and larger AVR chips, but never one with the ATtiny85. That’s why I decided to make one. This mood light is super simple to make and all the parts can be purchased online for about $5.00 total (not including the Arduino used to program the chip).

Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc.

Hall sensors works on the principle of Hall Effect proposed by Edwin Hall in 1869. The statement proposed says, âThe Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.â So, what could

Flexible circuit boards offer numerous advantages. However, the mechanical fixation of these circuit boards is highly complex. HARTING has developed a new solution based on 3D-MID technology that is capable of replacing flexible circuit boards. Thanks to component carriers, cost savings of up to two-thirds can be achieved. At the MID process, on the injection
