Modifying AVR Development Board and Programmer

Programmer and Development Board from Extremeelectronics: Look at the below picture. The programmer I am using is bought from another manufacturer, not from extremeelectronics. It is an USB Porgrammer. You can get it from any leading electronics hobby electronics store. My programmer is not pin compatible with XboardMini which I brought from extremeelectronics. I modified the ISP connector for connecting the USB programmer with the board. The XboardMini does not has Vcc connection in its ISP connector. My programmer has Vcc connection in its ISP connection. 10th pin is free (not connected) in the Xboardmini ISP circuit. I modified my cable such that 9th pin gets Vcc from USB programmer. The red wire I connected goes from 10th pin to one of its Vcc node. In this way, the board directly gets Vcc from USB power supply. You dont have to use 9V adaptor for programming and powering the board. I dont know whether the usb programmer from extremeelectronics is having Vcc connection in its ISP P...

Interfacing a DS18S20 with an AVR

This can be a complete project on its own - a simple DIY digital thermometer with LCD display and only a handful of parts - ATMEGA88, DS18S20 and only a resistor running off a regulated 5v supply. Display type - LCD (can be 16x1, 16x2 or anything larger) Controller: ATMEGA88 Programming Language: BASIC Compiler: mikroBASIC PRO for AVR ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''...

Line Follower Robot with AVR ATMega8535

Line Follower Robot with AVR ATMega8535 - Make the robot line follower is exciting, especially for those who like to friends experimented with AVR microcontroller ATMega. "Line Follower Robot" is a robot designed to follow the trail (can be a line putus2 line or even a point to point). Creating a Line Follower Robot uses an AVR microcontroller ATMega 8535 is very possible and very reliable. Due to the design of a Line Follower Robot should we think that the trail will be followed step by step Line Follower Robot will be made to track or path in Line Follower Robot is passed. And of the Line Follower Robot needs tersbut feature2 owned by AVR microcontroller ATMega 8535 is sufficient and meets the needs of the Line Follower Robot. Line Follower Robot in the article with AVR ATMega8535 I made a simple graffiti to be possessed by a Line Follower Robot.

AVR Stick – A Simple USB Data Logging Device

The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a ‘timestamp,’ from two pins on an ATtiny85. The device uses open source firmware availabe from Objective Development (http://www.obdev.at/vusb/) called V-USB to implement the USB 1.1 standard. The code that runs the application was based on the EasyLogger example application from Objective development.

Battery Charger based on AVR ATMega 8535

Battery Charger in general can be interpreted as a means to recharge the battery charge. Principles of good charger circuit is capable of providing resources to perform effectively charging the battery, efficient and safe. AVR-Based Battery Charger ATMega 8535 With LCD Display This is an idea that had just emerged from the author. In AVR-Based Battery Charger design ATMega 8535 With LCD Display is using AVR microcontroller processor charger with ATMega 8535, process the data viewer charger with LCD, a safety from a hot temperature with the temperature sensor LM35 and several buttons for setting the charger. And component power charger Battery Charger Based on AVR ATMega 8535 With LCD Display is a FET. Click to view larger Function-Based Battery Charger Part Series AVR ATMega 8535 With LCD Display ATMega 8535 AVR microcontroller serves as the controlling process of the charger. Button S1 - S5 as input data charger settings (setting the current, maximum temperature, peak voltage batterie...
