Interfacing SSD1306 OLED Display with Arduino
Posted on: 10 Jun 2018
Most of us would be familiar with the 16×2 Dot matrix LCD display that is used in most of the projects to display some information to the user. But these LCD displays have a lot of limitation in what they can do. In this tutorial we are going to learn about OLED displays and how […]
BOM/Component manager for KiCad
Posted on: 09 Jun 2018
IMO, KiCad is one of the best EDA tools out there, with just one major problem: Bill of Materials management is rough. If you make more than 1 board a year, you probably know how frustrating it can be to get everything together for an order. There are multiple ways to export a BOM (each […]
Open-Source SWD Programming Adapter
Posted on: 08 Jun 2018
After making the switch from AVR to STM32 microcontrollers, I redesigned my old 6-pin ICSP pogo-programming adapter for SWD. The new design allows programming with pogo pins or a small pin header soldered to the pogo pads for debugging, all with the same cable. The footprint uses surface mount pads only, so it can be […]
How to Send Data to Web Server using Arduino and SIM900A GPRS/GSM Module
Posted on: 08 Jun 2018
Today we are here with an interesting project in which we will Send Data to the SparkFun server using Arduino and GPRS. This is an IoT based project in which we will use GPRS, present on the GSM Module SIM900A board, to send some data to the web service on the internet. In this project, we […]
ESP12e + OLED display – a try to make a smartwatch
Posted on: 07 Jun 2018
Description Recently I bought two ESP12e, wanted to see how those IoT things work. One thing I know for sure, they don’t tolerate 12V 1A 😉 yep fired one by accident … I left with one working, trying to figure out what should I build with it. In the meantime was wondering should I by […]
Testing DRAM Using an Arduino
Posted on: 06 Jun 2018
A couple of weekends ago I was in the mood to do some retrogaming and didn’t know what I wanted to play so I asked for some suggestions from Twitter. I played some Castle Wolfenstein, Snake Byte, BC’s Quest for Tires, and Miner 2049er on the Apple IIe and then I wanted to try some […]
Arduino Data Logger (Log Temperature, Humidity, Time on SD Card and Computer)
Posted on: 06 Jun 2018
As Engineers/Developers we always rely upon the data collected to design or improve a system. Recording data and analyzing them is a common practice in most of the industries, here we are building Arduino Data Logger Project where we will learn how we can log data at a specific interval of time. We will use […]
Li-Fi – 200 Gbps via your room light
Posted on: 05 Jun 2018
Li-Fi (/ˈlaɪfaɪ/; short for light fidelity) is a technology for wireless communication between devices using light to transmit data. In its present state only LED lamps can be used for the transmission of visible light.[1] The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh.[2] In technical terms, Li-Fi is […]
Generating Tones by Tapping Fingers using Arduino
Posted on: 05 Jun 2018
In this project we are going to build a piece of entertainment using Arduino. We all have that habit of tapping Table or Pen for creating any random music. Of course it might not be considered as a good mannerism, but we all enjoy doing it at least once. Hence I thought of taking it […]
Smart Knock Detecting Door Lock using Arduino
Posted on: 04 Jun 2018
Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In […]
