Grove Beginner Kit for Arduino

It’s been a while since I took the old Arduino out, blew the dust off it, and yet again attempted to make something.  We’ve had a love/hate relationship, as I’ve sometimes struggled to overcome my knowledge deficits, but more on that later.

I was prompted to revisit the world of Arduino when I was recently delighted and intrigued, to be contacted by Seeed Studio, to feature their Grove Beginner Kit for Arduino on this blog.  I accepted their offer of a free beginner kit in return for this blog post….

Arduino Altimeter

This is a revisit to the CanSat project to share some tips on how to use a simple MPX4115A pressure sensor as an altimeter.  In a previous post I shared how to set up the sensor to detect ambient pressure, so now that we have that data, how do we estimate our altitude?

Testing SD Cards with Linux

While on holiday recently, my wife bought a 32GB micro-SD card, which she intended to use in her tablet.  Since then, it has been giving various errors, so I thought I should take it and verify its quality.

In order to test the card, we’re going to run three tests:

1. Access Speed, to assess the card Speed Class.
2. Drive Size, to assess if the reported size matches the actual size.
3. Data durability. to assess that data written can be read back reliably.

How To Take Timelapse Photos with Raspberry Pi

As part of our CanSat endeavours, we are going to use a Raspberry Pi to do some time-lapse photography as we descend after launch.  In order to do this we’ll need to configure our Pi to do this automatically.  Read on for a description on how to do this.

How To Measure Air Pressure with Arduino

Continuing with our series on CanSat, we discuss how to detect atmospheric pressure using an Arduino Uno R3 and an MPX4115A Pressure Sensor.

Temperature Sensing with Arduino

As part of the CanSat Primary Mission, we need to measure temperature.  For this our starter kit has given us an Arduino Uno R3 micro-controller, as well as some resistors and an NTCLE101E3 NTC Thermistor.

Introduction to CanSat

I’ve been fortunate to become involved with the CanSat competition in Ireland this year.  I’m playing the part of Industry Mentor to a team of students from Gairmscoile Mhuire, Athenry, Co. Galway.  Our team have called themselves Gairmsat.

Arduino Uno by Snootlab

A few months ago, my local maker-space (091 labs) presented a few informal tutorials on Arduino.  Having seen it mentioned online, I decided to bite the bullet and drop by to learn more.  Shortly later I purchased the Experimenter’s Guide for Arduino, which was used during the tutorials.  Being further interested in Arduino and it’s capabilities, I subsequently bought the Arduino Cookbook, by Michael Margolis (O’Reilly).
