The very first project of my channel is about controlling an RGB LED using annoying push buttons…. I feel that the project was not a good one to learn about micro-controllers, because most of the micro-controllers uses are not fully utilised in that project…. So, This is definitely the time for an upgrade, and upgrade means letting
If you have noticed in an office before, you would be probably aware of those RFID cards or Tags that would unlock specific doors depending on your access.Well let’s make a simple NodeMCU RFID reader using the MFRC522 module, and program the NodeMCU to provide access when the right card is detected. This simple example

Some time ago, I tried to make an “Instructables Hit Counter” using the Instructables API, and an Arduino Uno with a wired network shield. However, with the limited RAM of the Arduino Uno, I was unable to get the system to work. A while ago, I noticed a similar project done by diytronics using a NodeMCU. This was just

Particle Photon is a tiny micro controller, just about the size of an arduino nano. But the photon is designed for easy IoT prototyping, it supports OTA updates to its firmware. So all we have to do is get it connected to the internet and we could do all the programming wireless, the photon uses a

Hi makers! This is my first instructables and I want to address some important things firts: I made this project with the idea of using the lest amount of tools so that everyone could do it! Even I don’t have lot’s of tools, only the strict necessary I’m not an electrical engineer or a coder,

OLED!! What is an OLED? OLED ( Organic Light Emitting Diodes ) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and

We went all ‘cord-cutter’ and ditched our Cable box and realized something was now missing in our family room…the oh so familiar LCD clock that was always present. I decided to get to work on a replacement and had some fun with it. If you’re like me you’ve ordered an Arduino kit here and there when the
ESP8266 ESP-12E Arduino Clock W/ Outside Temp & LEGOS & NeoPixel Ring Continue Reading
In this project we will use an iPhone to control devices connected to an STM32 device. The project is a starting point for more exciting experiments such as remote controlled robots or any other thing you might want to control in your home. I encourage you to check out the source code which is really
Controlling Devices in Swift With BLE Continue Reading
For my first IoT project I wanted to build a Weather Station and send the data to data.sparkfun.com. Small correction, when I decided to open my account in Sparkfun, they were not accepting more connections, so I choose another IoT data collector thingspeak.com. Continuing… The system will be placed on my balcony and will retrieve temperature,

The goal of this project is to build a cheap alternative to measuring CO2 ppm in the air. It’s a nice simple way to see over-time change in ppm using a cheap NDIR carbon sensor and a temperature/pressure sensor to achieve better accuracy. In this project you will need to: – Solder – Wire –
