AVR Programmer using ATTINY2313 microcontroller

AVR ATmega Projects, Microcontroller Programmer Projects / Ibrar Ayyub

INTRODUCTION AVR910 is a very useful programmer. It can program almost complete range of AVR chips. The original version made by Klaus is here, http://www.mikrocontroller-projekte.de/Mikrocontroller/AVR-Prog/AVR-Programmer.html. The programmer uses ISP capability of AVR chips. AVR910 first appeared in AVR910 application note by ATMEL. It is one of the fastest programmers for AVR. We can use AVR

Output number when button is pressed using Atmega16 microcontroller

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

This is simple demo program of reading button state, lighting LEDs, sending information via USART. 8 buttons are connected to Atmega16 port A, 8 LEDs to port B via current limiting resistors. While none of buttons arent pressed there is running light on LEDs performed, but when any of buttons is pressed then LEDs display

Running TX433 and RX433 RF modules with AVR microcontrollers using Atmega8

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

Sometimes in embedded design you may want to go wireless. Might be you will want to log various readings of remotely placed sensors, or simply build a remote control for robot or car alarm system. Radio communications between two AVR microcontrollers can be easy when specialized modules are used. Lets try to run very well

Door Chime Privacy Sentry using Attiny12

Home Automation Projects, Security - Safety Projects / Ibrar Ayyub

An ATtiny12 controller as a timer and some switching circuitry turns the doorbell off for 10 hours at the same time each day. The string of resistors across the top of the board are series connected to make a 728 Ohm 2 watt resistor. The slide switch is used to switch the circuit between the

Nikon Camera Remote Control using ATtiny13 Microcontroller

Video - Camera - Imaging Projects / Ibrar Ayyub

This is an IR remote control for Nikon cameras. It is compatible with the Nikon ML-L3 remote control. Supported cameras include: D40, D40X, D50, D60, D70, D70s, D80, Coolpix 8400 8800. This design is based on an idea from http://www.bigmike.it/ircontrol/. The circuit is extremely simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery.

Barker Code-Locked Loop Synchronous Demodulator using ATtiny2313 microcontroller

Other Projects / Ibrar Ayyub

A simple, low component count phase locked loop that locks onto and detects the amplitude of an incoming baseband 7 bit Barker code using a switched resistor demodulator that is driven directly by a microcontroller’s output pins. Balanced modulators using resistors and a microcontroller’s output pins. Locking into oncoming Pseudo-noise (PN) stream. Microcontroller modulates its

Prime Calculator is Complete using ATMega8 Microcontroller

Calculator Projects / Ibrar Ayyub

My microcontroller-powered prime number generator/calculator is virtually complete! Although I’m planning on improving the software (better menus, the addition of sound, and implementation of a more efficient algorithm) and hardware (a better enclosure would be nice, battery/DC wall power, and a few LEDs on the bottom row are incorrectly wired), this device is currently functional

LED Dog Collar using ATTINY2313 Microcontroller

LED Projects / Ibrar Ayyub

LED Dog Collar So this is a pretty simple project, but I thought it was a clever idea. I have 2 dogs, a lab and a lab mix. The lab “Sunshine” likes to runaway a lot if we let her outside at all. She always comes back, but we can’t find her whenever she leaves.

BUILD A SIMPLE SERIAL PROGRAMMER FOR AVR DEVICES using ATtiny2313 Microcontroller

Microcontroller Programmer Projects / Ibrar Ayyub

Atmel described a simple programmer based on the AT90S1200 (NOT the AT90S1200A) controller in their application note. AVR910 (a modification to use the AT90S2313 is also given below). The circuit is so small and simple. I was able to put two of them together without using a printed circuit board. Taking only about an hour
