I’ve been keen to do some temperature monitoring. This is IoT basics 101. I thought of a use case for my Beer Brewing. Jaycar had DS18B20 temperature sensors at $7.90$ NZ each. They are cheaper than the DH11 & DH22 which are more expensive as they do humidity as well. So I thought I’d start
I came across Node RED as I was looking into IoT projects to do with Raspberry Pi. You can use it on PC’s and on Raspberry Pi’s, it comes installed in the Noobs package. It is an Open Source visual programming language that you plug actions into each other to create a flow of actions.
While on the Raspberry pi site, in the download section, there is a 3rd Party OS for Windows and I thought I’d like to try that out. My VPS is a windows server and I thought it would be interesting if I could boot the RPi up with different OS’s. There is a setup page
Further to my earlier article ” Physical Ms Flow button -IoT part 1” I have been tinkering around with Arduino code & Flow buttons a bit more. Some successes and some failures. The failures I cannot seem to connect to the device any more. So updating the code in Arduino desktop does not re-install on
After my partial success with the Arduino chip button test I thought I’d dust off my Raspberry Pi 3 Model B that I’d bought years ago. I hadn’t played with it, I’m not sure why. I’d taken it out of its packaging but hadn’t even installed the micro SD card with Noob setup. So I
I went to a Dynamics 365 Saturday event with lots of talks on Microsoft platform. There was a goody bag with a ESP8266 microchip device and a link(QR Code) to a web page & video on how to set it up as a “Panic Button” which will sent a message to your phone when pressed.
Somewhere I came across Standard Library but best searched for under StdLib. I signed up for it and found a couple of videos. It looked like magic and required serious coding, so I put it down at the time. I have been receiving regular “onboarding” emails (Seems pretty common and irritating when you sign up
I saw this great YouTube video about QR Attendance Using Google Drive with QR Codes Generator Add-ons: I thought it was a great workflow and also an elegant solution. The autoresponse from scanning the QR code to fill out the form. How easy is that? Then I got to thinking how I’d use it. I
I was looking at the GlideApps showcase and the Bogdan Popa created a News App. In it he uses IMPORTXML in Google Sheets to pull in web data that he filters to different tables. A nice app. I started thinking about what other import formulas does Google Sheets have, I know it has GOOGLEFINANCE
