TANK ROBOT ATMEGA48 BLUETOOTH JAVA PROJECT

Introduction After two more complex robots (¬†Eurobot2008¬†and¬†Robot2¬†), I decided to build a small and simple car.¬†The choice fell on a plastic tune, which was controlled by two AA pencil monoculars – similar toys can be found in toy shops, on soils or in bazaars.¬†Others are available on the Internet (for example,¬†Snailinstruments.cz¬†has several of them – […]

Enhancing An FM Transmitter’s Firmware using ATmega48

This hack is about rewriting the firmware of PLL FM transmitters based on AVR microcontrollers to add more functionalities. They’re commonly available on eBay from various sellers and for prices ranging from $40 to $80, depending mostly on the RF output power. If you don’t know if a similar transmitter is based on an AVR

Flickr images on a Nokia LCD using ATmega48

LCDs are often used in microcontroller projects. Most used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. Some time ago I ordered a Nokia 6100 LCD including breakout

Multichannel USB Analog Sensor using ATMega48 Microcontroller

Sometimes it’s tempting to re-invent the wheel to make a device function exactly the way you want. I am re-visiting the field of homemade electrophysiology equipment, and although I’ve already published a home made electocardiograph (ECG), I wish to revisit that project and make it much more elegant, while also planning for a pulse oximeter, an electroencephalograph (EEG),

Nixie Clock with AVR using ATmega48 microcontroller

Introduction: This is the hardware and source code for an Atmel ATmega48 based four digit Nixie Tube Clock. Description: This was my second Nixie clock project. I wanted something a little smaller / cheaper / simpler then my rather large B-7971 clock. I will post the design for that one of these days. Trying to

Simple Automatic Battery Discharge Analyzer using ATmega48 microcontroller

The project allows you to analyze characteristics of unknown/junk battery especially the capacity and variation of the voltage on discharge. It is controlled with a PC via a serial port. No external power supply is required because it is powered by RS-232C signals. It uses ATmega48 as main controller for dummy load and constant current

Open Source AVR Temperature Controller using ATmega48 microcontroller

The open source project allows you to control DC appliances based on the temperature of two thermistor inputs. It uses AVR ATmega48 as main processor. The controller has both green and white LEDs to indicate status. The project output is connected to N-Channel MOSFET, AOD444, for switching with current up to 4A. For higher current
