Received this Learning Lab Kit on a Shield for Arduino from Programming Electronics Academy today and am very pleased.  

The Learning Lab Kit on a Shield for Arduino is meant to help you save time – it basically pre-populates common circuits for you.

Circuits that you might already have learned quite ...

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 ...

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.

Pretty cool huh?  If you enjoyed that you may also ...

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 ...

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 ...

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.

The 7-segment LED backpack is obtaining it's power from the VIN pin of the Photon, which ...

Debugging interrupt service routines can be very tricky.  It's not like you can print out variabes 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 ...

3x4 Matrix keypad connected to an arduino. Displaying results of key pressed on a 7 segment led display via 74HC595 shift register which reduces the required pins of the 7seg display from 8 to 3.
