In my last post a few weeks ago, I built a Temperature Sensor using an Arduino. This temperature sensor was limited to reading the current temperature using an LM35DZ sensor. I could’ve wired it up to a I2C display (Perhaps I’ll have a separate post for it). However, the real fun begins when sensors are able to communicate over the Internet. That way you can record and graph the data.
In this post, I’m going to take you through building a WiFi temperature sensor using the popular ESP8266 dev board.
Codewars is an interesting website for enhancing your coding skills. I have been playing around with the site for a while trying to get better at Python. I came across the “Pick Peak” problem on codewars that I found very interesting. In this post I’ll take you guys through the Solution to Pick Peak problem on Codewars. The ‘Pick Peak’ problem was fun and interesting. Here’s the problem.
I purchased my domains from Godaddy about 8 years ago. Since then I’ve been using them on and off for web hosting some content and essentially parking my domains (with no income). I’ve stuck with them because their prices were competitive. However, logging into Godaddy’s web portal to manage anything was a poor experience. It’s like wading through the 90s popup ads on the Internet with absolutely no popup blockers. They have gotten better about it lately but they still try to upsell all the time. This is very annoying to the normal user.
A temperature sensor is an interesting application and I decided to build one using my Arduino. To build this, you’ll need basic understanding of Arduino and you should be familiar with the Arduino IDE as well as some basic electronics concepts. Continue reading “Temperature Sensor using Arduino”
