I bought an accelerometer sensor ADXL335 and ArduLog several months ago. Everything was nicely packed and delivered on time. What makes me really happy though is the after service I recently received. Several months after my purchase I ran into some problems with modifying the example provided by Hobbytronics. After being unlucky on the Arduino Forum (https://forum.arduino.cc/index.php?topic=506513.0) I contacted Hobbytronics for help. Following Mike's suggestions we discovered that it was due to a bug in the Arduino code base not the example sketch. Changing Arduino IDE solved the problem. Thanks Mike, great service!!
