Arduino and an LM34 temperature sensor

| July 30, 2009

Ok, so this is nothing that hasn’t been done before. But I’ve been working on another project, and it is just driving me nuts, so I need to take a break from it, and do something else. Maybe not “simple”, but “achievable!” I ordered some LM34 temperature sensors to play with, and threw together an […]

Another revisit to my analog meter clock

| August 23, 2008

Since I’ve been playing with Lady Ada’s Ethernet shield, I figured I’d see if I can do something useful. I wanted to see if I can get network time, which was a fair pain in the you-know-what. “Real” network time is via NTP, which is not exactly a walk in the park to manage at […]

Arduino, XPort ethernet sheild and serial LCD

| July 29, 2008

I picked up an Xport ethernet shield from LadyAda and played with it for a bit, and this is what came out. And inside the box This is an Arduino Diecimila with the Ethernet shield, and a SparkFun serial LCD, shoved into one of my unfamous wooden boxes. The code is very simple and very […]

Playing with arduino, again

This is just another test, a learning exercise. Flash, but it overloads the LEDs: No light, so that the display can be seen: code

PWM clock step 2

| December 24, 2007

I woke up in the middle of the night with an idea how to better deal with the minutes and hours settings. Since I am polling the switches, rather than interrupting, I might as well enclose the test in a bracket and be better able to handle it. Basically using a while statement when reading […]

PWM clock revisited

| December 23, 2007

After looking at my unfinished project for the past few months, I finally decided to pick up where I left off. The last thing I needed to figure out was a way to set the minutes and hours, and I was hoping to use an interrupt. I was already using INT0 for the calibration mode, […]

Analog meter clock

| August 7, 2007

This is a silly little project I’ve been working on for about a week. Basically, a clock using analog meters: This is based around an Arduino board which I purchased from SparkFun for $35. I didn’t order the proto board, etc, and re-used an old 5vdc wall-wart for the power supply. It probably looks ugly, […]
