The article covers how to interface an accelerometer with the atmega32/atmega16. Before proceeding, the user must know the basics of ADC (Analogy to digital converter) of the AVR.An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they […]
What’s with mint boxes and electronics? Beats me, but they are somehow made for each other. I had built ladyada’s USBtinyISP v1.0 circuit on a breadboard which I used every other day. It worked sporadically(and never at hour of need), used up half of my breadboard and looked ugly. So I decided to try my hand
Cap’n ArrDrownHo! is the lovechild of Ardweeny and Boarduino and he’s here to commandeer your AVR ships. ArrDrownHo! inherits pros of both and cons of neither. Pick up an AVR chip and start prototyping instantly on a breadboard! Want to replace that costly Arduino in your project with a cheap AVR, but don’t know how? Use
If you like this instructable, please vote for it! For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There’s a couple of commercial products that can do this, but not with the flexibility I wanted. I designed a Arduino micro-controller based solution
As usual, I’ve been all sorts of busy, with little time to blog about it. I did recently score a cache of small, nay, tiny AVR chips recently, and my wife had an interest in making something with them (maybe I can get her to guest-blog about it). Anyways, I was at a local hacker
Just from pure passion to see how low-end PIC exercises AVR, I made this programmer. Basically it is STK500 port on PIC16F1825. I took this http://www.tuxgraphics.org/electronics/ … 5101.shtml one, did some clean-up, wrote new hardware layer for PIC16 and voila – new programmer is born. It was done in one evening and night, ready to
I always like a challenge, so when I saw [simpleavr]s vusbtiny programmer, I started to wonder how small I could make an AVR programmer. All in all I’m pretty pleased with the result. The schematic is almost the same as the original one. I only added a LED an resistor to indicate a proper power
Here is my Chronos watch controlled rover. The rover has a CC1110 minikit that receives SimpliciTI messages from the watch and sends this to an Arduino (AVR) over serial. The Arduino controls the motors and the servo controlling the robot arm. I have called this thing a robot, which is not strictly correct, as a

Frequency meter with some of quite good performance, capable of measuring frequencies from 1Hz to 10MHz (9,999,999 Hz) with a resolution of 1 Hz over the entire range. Ideal for function generators or as a standalone meter. It is cheap and easy to make, with parts that can be bought anywhere, and with a small
This is as simple routine how to read 4×4 keypad keys using AVR-GCC language. The keypad is connected to AVR microcontroller 8 bit port. In this example it is B port. You can change ports depending on your needs – this is only an example ant it is not the only way to this. Howt
