Digital oscilloscope GLCD using Atmega32 microcontroller

Leave a Comment / Using Atmega /

This project describes how to make a digital oscilloscope using an Atmega32 microcontroller and a graphics LCD. The GLCD used has 64*128 pixel dots (GDM12864A with KS0108 processor) and the AVR runs at 16 MHz using an external crystal oscillator. To enhance the speed further, it uses an external A/D converter chip, ADC0820. The sampling

A Little More Serious Frequency Meter using ATtiny2313 microcontroller

Leave a Comment / Using Atmega /

This is design for a frequency meter based on AVR microcontrollers. Maximum input frequency is specified to be 30 MHz in the multi-chip configuration, and in single-chip configuration, there are both 5 MHz and 10 Mhz versions operating with 10 and 20 MHz crystals, respectively. All versions have 9 1/2 digit resolution. I have  used

Arduino – Modifying a Robot Arm using ATmega328

Leave a Comment / Using Atmega /

Essentially another tutorial involving controlling DC motors. In this post I’m going to first alter a robot arm I had built previously from a beginners kit so that it can be controlled from Arduino. Then I’m going to write a series of posts on different ways to control the robot arm using Processing and other things. You should be able to
