Door Activated LED Lighting using Hall Effect Sensors using Attiny85 microcontroller

I’ve been meaning to make something cool for my dorm room this coming semester and decided that some custom closet lights would look great. In this Instructable, I’ll show you how to make some nice-looking LED lights that will turn on automatically using a hall effect sensor and a magnet. Edit: I’ve noticed a lot […]

Creating a charlieplexed LED grid to run on ATTiny85

This instructable was inspired by my first AVR microcontroller project that I’ve been working on for some time now. I wanted to start learning more about the AVR microcontroller and see how much I could do with the minimum amount of hardware… no extra chips, simple components, etc… just my AVR and my code so

Turn Your Arduino Into an ISP

AVR ATmega Projects, Video - Camera - Imaging Projects / Ibrar Ayyub

Learn how to turn your Arduino into an AVR In System Programmer. This will allow you to burn bootloaders onto new chips or program AVRs without a bootloader. Step 1: Materials To begin you will need: * Arduino (I will be using the Uno) * AVR Microcontroller (This tutorial will cover the ATtiny85 & ATmega644)

Apple-style LED pulsing using a $1.30 MCU using ATTiny85 microcontroller

AVR ATmega Projects, LED Projects / Ibrar Ayyub

The Atmel ATTiny85 chip is an 8-pin MCU that is totally awesome. If you’ve been programming with the bigger boys (the ATMega series), these are a nice adventure – you’re rather limited in the number of output pins, but a creative design gives us a lot of flexibility in a very small package. You’ve seen

New Jar of Fireflies

AVR ATmega Projects, Game - Entertainment Projects / Ibrar Ayyub

When I ran across the Jar of Fireflies Instructable sometime this past summer, I knew I had to build it. Full credit to Keso for an excellent set of instructions! I wouldn’t have gotten to the point of developing the firefly behavior without such a solid base for building the hardware, as well as firmware to start it

VUSBTiny AVR SPI Programmer Using ATtiny85

AVR ATmega Projects, Other Projects / Ibrar Ayyub

after making a usbtiny isp programmer and using it for 6 months, i was looking at making another one for carrying around. i like the simplicy of the usbtiny isp design but would like to make it even smaller and take less parts. one thing in the original design that i want to change is

Repair dead AVR's – Attiny fusebit doctor (HVSP)

AVR ATmega Projects, Other Projects / Ibrar Ayyub

Did you make a mistake while programming fusebits, or purposely disabled reset pin (RSTDISBL) or ISP programming (SPIEN)? No need to buy or make inconvenient HV programmer only for unlock couple of Tiny AVR’s. This Attiny fusebit HV doctor will cure your dead tiny microcontrollers, by restoring all fusebits to factory settings – nice and

Swiss AVR Knife using Microcontroller ATtiny84

AVR ATmega Projects, Game - Entertainment Projects / Ibrar Ayyub

The Swiss AVR Knife bundles a number of AVR programming projects together in a single convenient Altoids Gum Tin. Because of the flexibility afforded by microcontroller programming, it also provides a starting point for any number of projects based on LEDs and sound output. The SAK can contain as many programs as the 8K of

Debugging AVR code in Linux with simavr using Microcontroller ATTiny85

AVR ATmega Projects, RTOS - OS Projects / Ibrar Ayyub

I recently started programming AVR chips, namely the ATTiny85. They can be programmed using C, compilers are readily available in Ubuntu, and you can do a LOT with them – just search for avr on this site! Anyway, I was having some trouble with my project today – the LED wouldn’t flash! I couldn’t figure

USB PCB Business Card Using ATtiny85 Microcontroller

AVR ATmega Projects, Interfacing(USB - RS232 - I2c -ISP) Projects, Other Projects / Ibrar Ayyub

This is a business card that will type out some text when you plug it into a USB port. It uses a ATtiny85 microcontroller with V-USB based code to emulate a keyboard. The typing is triggered by the CAPS LOCK status LEDs being toggled 3 times. This instructable will focus on using CadSoft EAGLE to
