Weather Station with digital and analog display :: Member Project

Ever want your own weather station? What about one with analog and digital displays?

Martin Cury, a member of Programming Electronics Academy, built an Arduino based weather station with both analog and digital displays using the BME280 sensor (an environmental sensor with temperature, barometric pressure and humidity).

His design uses an Arduino compatible Mega AT2650 clone, three servo motors, and an OLED display among other things.  Checkout some of his photos below!

The weather station uses 3 servo motors that adjust a pointer based on input from the BME280 environmental sensor.

“I used your lessons to clarify the components and programming techniques” -Martin Cury (Editor note: Awesome!)

Martin soldered together a connector board for plugging in his servos, OLED display, and BME280 sensor.

He generated the scales used for the analog backdrops in excel with a little trigonometry and some macros.

During his prototyping, he used example programs from numerous Arduino libraries, the Dr. Duino Explorer kit to test components and work out issues, and expanded on the kit code for displaying the temperature.

“The code is not as organized as I would like but the objective was to make it work” -Martin Cury (Editor note: I know that feeling!)
