Portable Arduino Barometric Weather Station

In this video lesson we take you through the project of building an Arduino Barometric Pressure Weather Station. It builds on the last two lessons in this series. We measure and display instantaneous Barometric Pressure, normalized to Sea Level. Then in the lower portion on the OLED SSD1306 display, we show a graph of the barometric pressure over the last 24 hours.

 

Schematic for the Portable Arduino Barometric Pressure Sensor

When using the breadvolt, or any battery power supply on a breadboard project, do not turn the power supply on while the Raspberry Pi Pico is connected to USB, as you could generate voltage conflicts. It is an either or. If the USB is connected, the power supply should be OFF. Or if you are going to connect the USB, first turn off the power supply.

Below we include the code we develop in the above video. Make sure to set the ‘alt’ variable to your elevation at your location, in meters.

 

Arduino Tutorial 24: Understanding Passive Buzzers

In this lesson we show you how to incorporate sound into your project using a passive buzzer. Passive Buzzers have the advantage that they are less expensive than active buzzers, and you can more precisely control the tone. This lesson will show you how to hook up the buzzer, and then how to code the arduino to produce different tones.

If you want to follow along at home, an official Arduino Uno R3 is available HERE. In this new series of lessons, I will be using the sensor and other components found in this KIT

The Ultimate Raspberry Pi Project: To the Edge of Space with Raspberry Pi

We have what we consider to be the Ultimate Raspberry Pi project . . . we send a Raspberry Pi instrument package to space, and telemeter live data back to earth, including live video over HAM radios. We do the telemetry with an innovative technique we call Ethernet over Ham, where we use the 2.39 GHz Ham band right below commercial WiFi.

We have had 5 successful launches, and are preparing for the launch of Eagle VI in Early February, 2017. Watch the video and see a live demonstration of our raspberry pi based system. Enjoy!
