I2C Data Logger Using ATmega328p and DS3232 – I

There is a popular data logger shield out there designed for Arduino using a DS1307 real time clock chip. And […]

The official Arduino Duemilanove board is an excellent tool for prototyping. For most of the users, it is a very […]

One of the goals in my previous timer project was to achieve the ability to control multiple electronic devices using […]

To measure how flat a surface is, you typically will need a level of some sort. In this article, I […]

One of my recent projects was to build a POV display device. There are already many microcontroller based POV devices […]

When I was doing the clock/stop watch project last month, I mentioned that I intended to add I2C (TWI) communication […]

This is what I ran into for the first time: I was flashing the chip the other day and after […]

Over the past couple of weeks, I have been experimenting with BQ3287, a real time clock module from Taxes Instruments. […]

LM19 is an analog temperature sensor that operates over a while temperature range (-55 to 130 Celsius). It is very […]

ATmega328p does not provide any Digital/Analog conversion channels (although the D/A conversion can be simulated by means of measuring the […]

I have been using the bit-banging method to boot-load ATmega328p with Arduino bootloader for a while, and Kimo’s method worked […]

In my last post, I described in detail how to hand solder LIS3LV02DL, an LGA packaged accelerometer chip. And here […]

LIS3LV02DL is a MEMS three-axis digital linear accelerometer that provides both I2C and SPI interfaces for communicating with microprocessors. My […]

I was inspired by Paul’s 7 segment display and decided to build one myself. He used 4 common cathode 7 […]

I have been using the FTDI bitbang method piloted by Kimio Kosaka and improved by others (1,2,3) to flash Arduino […]
