Arduino GPS Clock
I built the Arduino GPS Clock by Tony DiCola over at Adafruit. The clock was very cool, setting it’s time from the satellites, however, I soon started feeling like I was wasting my GPS shield by only using it to get time. So I decided to use the RGB LCD Shield which
Track A Car Using Tiny Arduino GPS with SD Card
This is a really cool project that was originally on Make as a GPS Cat Tracker. Michael James, at the Programming Electronics Academy, put together an excellent 10 minute video showing you how easy it is to do this project.
A great Arduino project book and site
I received a message on twitter asking if I knew how to test if a GSM Sim900 module was working. I have not worked with that module hands on but did recall a great write up on it from a trusted source, John Boxall of http://tronixstuff.com. I learned of John through Arduinos site under Mannuals and Curriculum. His […]
Particle Photon – The Buddy System: Publish and Subscribe
This is a demonstration of the Photons publish and subscribe features. When the photon publishes an event to the cloud it makes that available to other devices that have subscribe to the event. The other devices is not just limited to other photons but could also be internet connected smart phones ore web browsers.
A Simple LED Clock using Particle Photon
This is a simple LED clock I prototyped following Simon Monks post. I am using a Particle Photon, a couple 4.7k resistors and a 7 Seg Display with an Adafruit I2C backpack.
Syncing Oscilloscope To Interrupt Activity
Debugging interrupt service routines can be very tricky. It’s not like you can print out variables to the serial port as you might when debugging code outside the interrupt. One way you can can get some idea of what your code is doing in the ISR is to pulse one of the GPIO pins while […]
