Coil Winding machine counter with Atmega8 and Reed relay

Connectors Everything has been mounted on a test board, including the headers for: ISP programmer (USBAsp), the 5110 Nokia LCD, the power supply (5V in, fed to the 3.3V regulator), the Reed relay connector, the reset button connector and another 2 pins connector, used to read the polarity of coil winding machine's motor, so we know we either increment or decrement the counter. Connectors There are a few con ...

DS1307 RTC Interfacing with AVR microcontroller

In this tutorial we will learn How to interface RTC DS1307 with AVR microcontroller. We are using Atmega8 for the demo. GENERAL DESCRIPTION The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C™, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, ...

Microwave Controller using ATmega8 – AVR Project

The user interface has the following parts. Output Device: A 16×2 alphanumeric LCD Module is used as the main output device. It can display numbers, alphabets and few symbols. It can show two line and each line can have 16 characters. The backlight enables the text to be visible even in dark. A buzzer beeps when the system receive input from the user and the input is successfully processed. For example if t ...

A led matrix Mask built on AVR ATmega8

AVR Mask1 is a led mask built around 74hc595 shift register and 8x8 led matrix. The "Dylan Dog" comics decoupage, in conjunction with his stands, make it good looking.t has 4 8x8 led matrix, 2 for the mouth, and 2 for eyes. When the user get closer to the mask, the IR sensor placed on the back activate the mask. If activated, it randomly runs eye and mouth patterns. Patterns can be programmed in code, the p ...

SD card logger library with log rotation that fits on ATmega8

This library implements an SD card Data Logger that runs on ATmega. It has a small footprint, so it can be loaded on an ATmega8, leaving space for user code. It supports SD and microSD cards formatted with FAT16. It also features log rotation.The "Petit FAT File System Module" by ChaN (http://elm-chan.org/fsw/ff/00index_p.html) it is used to write on SD card. I've used the Petit library because i would like ...

Drive a stepper motor with acceleration and deceleration using an Allegro driver on ATmega8

The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation.Most common types of stepper motor can be bipolar or unipolar, depending on the winding. To make a stepper motor move, motor windings must be loaded in the correct order. A stepper motor move at steps, it's accuracy is usually expressed as degree per step. Microstepping is a method by witch motor accur ...
