New tutorials coming


I will be putting up at least 2 or 3 new tutorials here (and on Hackster) in the next couple of days. I had planned to finish them earlier, but I was slowed down by running into a few issues porting some libraries.

Anyway... new tutorials will be about:

5161AS 1 digit 7 segment LED -- super simple tutorial for beginners
Bosch BMP180 Barometric Pressure & Temperature Sensor
Fujitsu MB85RC256V FRAM (Adafruit I2C FRAM breakout)

Maybe after those I will write up:

DS3232RTC Real Time Clock possibly including AT24C32 EEPROM
HTU21D Temperature & Humidity Sensor

In the mean time you can find the precursor for the 5161AS tutorial here... it is the library and demo code on github,,,


O.K., so I am about a week behind where I wanted to be on tutorials... but I'm ahead on porting libraries. My aim is to get back on track with tutorials... the 5162AS mentioned above is done... Next ones will likely be the SH5461AS 4 digit 7 segment LED display... then the DS3232RTC real time clock & the bunch of temperature and humidity and/or barometric pressure sensors I have... HTU21D (pre-existing library), BMP180 (new port), SHT15 (new port) and possibly DHT11 (existing library) and DS18B20 (existing library) if the latter two sensors I have on order ever get here. The weather sensors will probably be paired with either 1602 or 2004 type displays. After that it is hard to say. I've got enough parts here to hopefully eventually do 20-30 tutorials. I may go back and do some really simple and basic ones before getting into the more complicated stuff.

One of the really cool things about the Esquilo is how easy the data from any one of these sensors could be served up to the Internet instead of being output on a local display...


Here is a pre-view of something I've been working on for a while...

Weather Station Shootout!

On the left is the SwitchDocLabs WeatherPiArduino hooked up to an Esquilo via I2c. This one has a Bosch BMP180 Barometric Pressure and Temperature Sensor on board with all the options... a DS3232RTC which also contains an AT24C32 EEPROM and a temperature sensor, an Adafruit HTU21D Temperature and Humidity Sensor, an Adafruit MB85RC256 FRAM, an Adafruit ADS1015 12 bit ADC and an Embedded Adventures MOD-1016 AS3935 Lighning Sensor. I also have the SwitchDocLabs wind and rain measuring add-ons which plug into the two supplied RJ11 jacks.

On the right is the Sparkfun Weather Shield. I have added stackable headers and RJ11 jacks to it so I can connect the same wind and rain instruments as mentioned above. This shield includes the HTU21D Temperature and Humidity Sensor onboard along with an MPL3115A2 Barometric Pressure Sensor and an ALS-PT19 Light Sensor. I don't have the optional GP635T GPS module yet.

Anyway... what my plan is, is to try each one of these out and see which one will be my permanent Weather Station solution hooked up with the wind and rainfal sensors. The by-product of that will be write-ups of my experiences with them including tutorials featuring many of the separate components.

I'd really like to hear from anyone who is interested in these weather stations.
