Introduction Last year, I had written a rather ponderous article on the Device part of the IoT triad consisting of Device, Mobile and Cloud. This time,nI want to focus on the Mobile part. In this article, I’ll go through the construction of a cross platform mobile app that displays heart
Introduction I like Atmel tinyAVRs because they are tiny computers that I can(almost) wrap my head around. The Atmel ATtiny4/5/9/10 are the cheapest in the tinyAVR line, and they come in two packages – SOT23 pictured above, and an even more stupendously small 2mm x 2mm USON package. This article
This is a brief account of my four-day visit in January 2016 to Shenzhen,n China. Due to my unfamiliarity with the language and brevity of the trip, this is only a superficial perspective. Why Shenzhen? If you are doing anything related to electronics today, you will come to know about
Introduction I was introduced to Atmel tinyAVRs a few years ago, soon after I started playing around with the Arduino platform. Now, here was a computer I could wrap my head around. Although it lacked the bells and whistles (voltage regulator, USB support, modest number of I/O lines, etc.) of
Introduction Diwali (or deepavali, the Indian festival of lights) is just around the corner, and in addition to stuffing myself with unhealthy snacks and scaring my kids with firecrackers, it's also the time to receive cheap LED lamps as gifts. ;-) So I decided to take one apart and make
Introduction In this project, we will build a two-wheeled robot based on the Nordic nRF51822 BLE SoC. Motor control for the two wheels of the robot will be done using an L293D chip. The robot can be controlled using any mobile device that has BLE, and when not connected, it
I wanted to create a simple project to teach soldering and electronics to kids (10+ years) and beginners. I first thought of a simple two transistor LED flasher, but then decided to make it interactive by adding a touch sensitive element to it. The idea is that once made, this
Introduction In this project, we will control two motors over BLE using the Nordic nRF51-DK. To do this, we will use a motor driver based on the Toshiba TB6612FNG chip. We will use GPIOs and PWM to communicate with this board. Background Before you read further, you might want to
I write this from the perspective of a maker. When I say project, I mean hardware project, and when I say writing I mean non-fiction writing. Motivation I have learned much from the work of others. And much of that learning came about because those people put in the effort
