IoT Starter Kit for Makers

There are so many situations where you’d want to add automation to an electrical appliance, remotely control it or to keep check on it in real time.

You’d probably start by making an Arduino based hardware device with needed components / modules. Programming firmware to read values and take actions based on those values, or just publish the values online service to access them from anywhere. Last part will be to have some way to get it talking with your mobile phone.

Introducing our Flutter ESP8266 IoT Starter Kit, its two projects in one pack!

Flutter ESP8266 IoT Starter Kit – App in Dark Theme

For last few years, we’ve been doing projects which needed such automation, remote control or monitoring. We developed a template project, cloned it for every new requirement and customized as per our needs. It’s a boilerplate with all the basic requirements such as device settings, connectivity, data publishing and most importantly keeping device connected.

We decided to help other developers by releasing a ready-to-go package, full source code of a Flutter based mobile app along with ESP8266 firmware. Its available now at CodeCanyon, follow the link below:

Once you get copy of Flutter ESP8266 IoT Starter Kit, all you have do to is open both projects one by one in VS Code, and build. The steps are described in online documentation, which are quite easy to follow.

App Screenshots and Wiring Diagram

We just added pre-compiled APK on product website so you can try out the app as well, visit the following link for more:

If you have any questions, feel free to leave a comment below, I’ll try to get back to you as soon as I can.

P.S. Pre-compiled app connects and share data from live embedded device. We just replaced relay board and buzzer with LEDs so it doesn’t make noise :)

Font Converter for Arduino

Currently working on a DIY project for my SUV where I needed to use ESP8266 WiFi enabled microcontroller with two tiny I2C displays and a GPS. I found a great display library by Daniel who goes by the name Squix, known for sharing Weather Station and other awesome open source projects. If you’re into DIY embedded hardware, do check out his blog https://blog.squix.org/

Squix’s display library can use font generated by online Font Converter which have good list of fonts to select from. Sometimes a custom font is needed, like in my case, and I struggled to quickly get my own font converted to supported format.

Searched for and found some options, but was not happy with them. Thanks to Daniel  for sharing source code of Font Converter, I digged the source and extracted just the part to convert the font.

I did bit of modification to pass font name, size and regular or bold option arguments to the console utility. I created a GitHub repo where source and compiled binary is available.

Usage example:

> java FontConverterV3 "Tahoma" 14 r > font-tahoma.h

Download and repo:

Soon enough, I will share the project which needed this utility.
