ESP32 H.A.N.D. Project Update

I’ve recently started an ESP32 project whose objective is to automate some of the tasks in my home. Since the last update on my web site, I’ve made some additions and changes to the project. To get updated on what’s new just read the rest of the article.

During my last article I’ve posted a photo of my project contained in two prototyping breadboards. I was waiting for the infrared motion detection module I bought online overseas. Here’s a photo of the current state of organized chaos of my breadboard.

What has changed

Since the last update here are some of the additions and changes:

  1. I’ve connected the infrared motion sensor module to one of the I/O pins of the ESP32.
  2. The voltage regulator temperature sensor module has been changed by just connecting a thermistor directly on the breadboard instead of using the bulkier temperature module.
  3. I’ve created a 5v/3.3v power module which can be connected directly to the breadboard power rails. It has more current capacity than what is available off-the-shelf. (More on how I made this in a future article.)
  4. A 16-key membrane keypad has now been connected to the system.

What’s next

Hopefully the other sensors I’ve ordered will arrive this month so that I can connect them and start integrating the pieces. Once they’re all connected, I will start posting regular articles to explain each subsystem.

Why am I doing this

My main objective has been to be able to automate some tasks around the house — necessity is the mother of invention.

I’ve decided to write about the project on iGerry to share my experience with others who may be interested — especially the younger generation. Hopefully, this will encourage them more to pursue their interests in Electronics.

I’ve been posting about the project on the different major social networks like Facebook, Instagram, Twitter, Linkedin, Google+ and Pinterest. You can follow me on those social networks to get updates.  I’m also thinking of creating videos about the project on YouTube if there’s people interested. if you’d like to watch YouTube videos about the project, please subscribe to my YouTube channel. If a lot of people are interested, I will start posting videos.
