Around the Bodensee by bike

With a small group I cycled from Konstanz to Konstanz via Bodman, Überlingen, Friedrichshafen, Lindau, Bregenz (AT), Rohrschach (CH) and Kreuzlingen (CH). We started on a Wednesday an 11:30 in Konstanz after arriving by train, stayed the first night on the Camping site Camping Birnau-Maurach near Uhldingen-Mühlhofen and the second night in Lindau at Park-Camping Lindau am See. The first camping site was quite fine, but the second was significantly better. :) The trip was 196 km in 12.5h riding time. We stopped in a few cities and visited city centers and harbors.

Reading sensor data from a DHT11

Reading data from an DHT11 using an arduino is fairly simple. Library used:


  • using arduino-mk
  • Arduino Linux 64bit package Version 1.0.5
  • (more see previous blogposts in arduino category)


  • Clone library in libs folder
  • Create Makefile
BOARD_TAG    = uno
ARDUINO_LIBS = DHT-sensor-library
USER_LIB_PATH = ../libs/

include /usr/share/arduino/
  • try example code:

My DHT11 has a different pin layout: - + S. The rest of the example code works without modifications.
