Digital Metronome — Revisited
Last year, I wrote about a simple digital metronome project. While the device worked pretty well there are a few […]
Simple Zener Diode Tester
In this post I will show you a simple Zenner diode tester circuit, when coupled with a PWM generator it […]
Arduino Library For MCP342X
Last time, I discussed how to interface TI’s ADS1112 16-bit delta-sigma A/D converter with Arduino. Today I am going to […]
Interfacing ADS1112 With Arduino
ADS1112 is a 16-bit delta-sigma A/D converter. This A/D chip has an I2C interface, a 2.048V internal voltage reference and […]
AD7705/AD7706 Library Revisited
About a year ago, I wrote a simple library for interfacing AD7705/AD7706 with Arduino. The library works, but it requires […]
A Self-Balancing Robot – III
In part one, I went over the theory behind the self-balancing robot and in part two, I showed you my […]
A Self-Balancing Robot – II
In my previous post, I explained the theory behind the self-balancing robot at a high level. Here, I will discuss […]
A Self-Balancing Robot – I
Building a self-balancing robot is one of those things that every hobbyist and engineer want to do. But there are […]
So Why I like Arduino
You probably know this already from just reading some of the posts in my blog. Like millions of others, I […]
Adding Off-Screen Buffer to Serial LCD Display
Since the current Arduino tools do not support in-circuit debugging, you will have to rely heavily on the serial print […]
Using FRAM as Nonvolatile Memory With Arduino
One of the biggest advantages of FRAM (or FeRAM, Ferroelectric RAM) over EEPROM is that FRAM has a much higher […]
Interfacing MMA8453Q With Arduino
MMA8453Q is a rather inexpensive accelerometer. It is significantly cheaper than many other 3-axis accelerometers (such as the popular LIS3LV02DL) […]
Makefile for Arduino 1.0
A while back, I created an Arduino plugin for NetBeans so that I could use the full-fledged NetBeans IDE for […]
Building a Wireless Temperature Sensor
I have built quite a few (1,2,3) temperature measurement circuits in the past, but none of those has remote sensing […]
Interfacing DS28EC20 with Arduino
DS28EC20 is a 20Kb 1-Wire EEPROM chip from Maxim. Like all other 1-wire devices, only a single pin is needed […]
