Thermometer using an arduino, a 7 seg display and a DS18B20
Today I pieced together a small arduino project using a temperature sensor and a 7 seg display.
The video below pretty much sums up the functionality.
I'm quite satisfied with the results given how little time I put into the project.
The arduino is a great platform to base your project on as the number of support libraries truly speed up your development. For instance, getting the temperature sensor up and running took only a couple of minutes.
The hardest part of the project was to try to minimize the flickering while doing the display multiplexing. There is still some flickering due to that some cycles need be spent quering the sensor.
I don't know if this is solvable without involving some external circuitry
