Last year, I created Crypto Price Tracker (an app which was acquired by Redwood City Ventures this year). A back end member of my team had been using an Arduino setup to check web server response statuses continuously to get updates all the time. I found that setup to be pretty useful and interesting.

I researched about it and recreated the setup for myself. In this article, I’ll show you how you can build it yourself, too.

Things that you need:

  1. Ethernet Shield for Arduino (to connect the Arduino to the Internet)
  2. Ethernet Cable
  3. A/B Type USB 2.0 …

Last Sunday, while I was explaining the basics of electronics and Arduino to my roommate, she challenged me to understand how a voltmeter works and build one from scratch just using the stuff I own already. I accepted the challenge, started hacking, coding, testing, re-coding, and re-testing, and finally I had my voltmeter ready and working by dinner time!

I used Arduino Uno (to collect voltage in analog and to power the LCD), a small LCD screen that I got in my Arduino starter kit (to display the voltage), a breadboard (to connect everything), and jumper wires.

Just a few days ago, I finished my WWDC 2018 scholarship submission. It was so much fun creating Alice in codeLand. This was my first year applying for WWDC scholarships, and I hope to get in!

Alice in codeLand is a three-in-one. It’s a hacker/coding simulator that looks like the Mac OS terminal that you can play with offline. It’s also a funny story of a hacker named Alice who tried gaining unauthorized access to Apple’s WWDC portal after succeeding at hacking into (a video sharing platform for toothpaste reviews) and (a social platform for macaroon lovers like…

And some tips for you to get started with both.

A few days ago, I published a post on Typography, a post on Color Theory, and a post on designing mobile apps from scratch. They received a good amount of attention, and people shared with me how helpful the posts were to them in understanding design better.

So, I decided to write another post that’s a quick introduction to two very broad topics: User Interface Design and User Experience Design. The knowledge from previous articles and this one can help you become a better designer.

Let’s start!

First off, let’s answer the question: What exactly are UI design and UX design, and…

I’ve been writing a fair bit on Medium recently, sharing valuable design and development knowledge I gained from working on my first app, Crypto Price Tracker that I just launched today, on 28th Jan.

I wanted to share my story of working on this app from the day I started until today. I hope this post helps and inspires other young programmers (or really anyone who’s interested in making tech products!) to acquire valuable technical skills, identify market needs, build great products with their skills that solve those market needs.

A bit of background on me: I’m a 16-years-old homeschooler…

I started learning graphic design when I was 13. I learned to design websites from online courses and used to play around with Photoshop and Affinity Designer all day. That experience taught me how to think like a designer.

I’ve been designing and developing apps for almost a year now. I attended a program at MIT where I worked with a team to develop Universeaty. Two months ago, I started working on a new app, Crypto Price Tracker, which I launched recently on 28th January.

In this post, I’ll share the step-by-step design process I follow along with examples of…

We’re able to see different colors because of our retina’s innate ability to differentiate frequencies of light waves.

Certain colors or shades evoke different sentiments in people. In this post, I want to give a quick introduction to color theory, ways to combine colors, and tools for designing with color — that you as a designer can benefit from to make your designs delightful.

Let’s start!

Different moods are attributed to different colors and you can use these different colors to achieve different ends.

  1. Red has been traditionally associated with Love, Energy, and Intensity. …

For digital design, it’s important to know and understand how to use and how to combine different fonts. There’s a font for every mood!

This post is going to give you a quick introduction to the biggest families in Typography: Serif and Sans Serif. And how, as a designer, you can choose the right fonts and combine them.

Let’s start!

Serif Type Family

3 weeks ago, I set out to work on a cryptocurrency price tracking app that offers real-time prices of hundreds of cryptos, alerts, portfolio, all in a beautiful and sleek interface.

I’ve been following the crypto market and using crypto price tracking apps since a few months and was utterly annoyed by the confusing interface, and not to mention so many ads! I asked my friends for suggestions for better apps, paid for a few more, and still disappointed. …
