The Google PAC-MAN logo is actually a live game!
Arduino Development Using NetBeans
The Arduino development environment is probably the preferred development platform for the majority of Arduino users. It is lean and […]
Working With LM19 Temperature Sensor
LM19 is an analog temperature sensor that operates over a while temperature range (-55 to 130 Celsius). It is very […]
A Library for LTC1665/LTC1660
ATmega328p does not provide any Digital/Analog conversion channels (although the D/A conversion can be simulated by means of measuring the […]
An Arduino ICSP Board
I have been using the bit-banging method to boot-load ATmega328p with Arduino bootloader for a while, and Kimo’s method worked […]
Interfacing LIS3LV02DL Using SPI — II
In my last post, I described in detail how to hand solder LIS3LV02DL, an LGA packaged accelerometer chip. And here […]
Interfacing LIS3LV02DL Using SPI — I
LIS3LV02DL is a MEMS three-axis digital linear accelerometer that provides both I2C and SPI interfaces for communicating with microprocessors. My […]
4 Digit 7 Segment Display Using Arduino
I was inspired by Paul’s 7 segment display and decided to build one myself. He used 4 common cathode 7 […]
On ATMega328 Bootloading With FTDI Bitbang Method
I have been using the FTDI bitbang method piloted by Kimio Kosaka and improved by others (1,2,3) to flash Arduino […]
A Simple Dual H-Bridge
H-bridge is frequently used to control DC motors and stepper motors. When controlling a bipolar stepper motor, two full H-bridges […]
A Power Inverter with Arduino Pulse Source
After going through some of the tutorials on Arduino’s site, I really started to appreciate what a powerful platform Arduino […]
Hello Arduino
When I first started interfacing electronics with computers back in the early 90’s my hardware choice was an ISA AD/DA […]
