Atmega 32u4 Based USB Digital Voltmeter

In this project, a digital voltmeter will be designed which will show the voltage reading on a desktop application. The device will read analog voltage with respect to the ground, digitize the reading and send the reading to personal computer on USB interface. The device could read four different voltages in range from 0V to 5V. For this, the device will be configured as CDC Class Device. A CDC Class device ...

Burn BootLoader into Atmega328P using Arduino Diecimila

I have an old Arduino Diecimila and some new Atmega328P-PU chips. Shouldn't have but I brounght some without bootloader to save some dollars. What next? search instructables to see if I can burn bootloader to ths chips. Unluckily not working. An error message "avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51" shown. There is a way to solder ...

Bootloading and Mounting Arduino Atmega328 – I made it at TechShop

This Instructable shows how to bootload and mount an Atmega328, Atmega328p or Atmega328p-pu for any project. This is a great way to save money by purchasing Atmega328 DIP package microcontrollers instead of using the Arduino development board itself. I put this together at techshop to be able to bootload microncontrollers for future applications they don't do a ton in electronics or programming but you can ...

I2C Bus for ATtiny and ATmega

I love the Atmel AVR microcontrollers! Since building the Ghetto Development System described in this Instructable, I've had no end of fun experimenting with the AVR ATtiny2313 and the ATmega168 in particular. I even went so far as to write an Instructable on using switches as inputs, and extended the Ghetto Development System concept to CPLDs. During a recent project, I needed several switches for setting ...
