SparkFun AVR Stick schematics

The SparkFun 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 repository is at https://github.com/sparkfun/AVR_Stick where you can find out more details. I like looking over the...

ATmega16 and MAX7219 8 x 8 matrix

This is a picture of the 8 x 8 LED matrix display I used which I connected to my ATmega16 Here are the connections CS -> PORTD 2 DIN ->.

Atmega16 and a 7 segment display

In this example we will show you how to connect a 7 segment display to our Atmega16. You can think of a 7 segment display as 7 individual LEDs in a configuration like the picture below. Image 1 shows the layout and image 2 shows how...

Atmega16 and 74HC595 shift register example

Sometimes in your projects you simply do not have enough I/O lines available, take for example a lot of the multiple LED examples, these use 8 outputs to control 8.

Attiny2313 and PWM led example

In this example we connect an LED to PB2 (Pin 14) of an Attiny 2313. The PWM output is obtained from the OC0A output of timer/counter0. Schematic Code Avr studio code example [codesyntax lang="c"] #define F_CPU 1000000UL #include...

Attiny13a buzzer example

In this example we connect a piezo buzzer to PB0 of our Attiny13a. We use mikroC pro for AVR which has a built in sound library to play a tone.

Atmega128 push button example

I recently bought a development board for an ATMEGA128, sadly there was no examples and no schematic supplied but after some trial and error I managed to get this up.
