We have been having some condensation and mould issues in our apartment recently due to, I think, the humidity levels. Our property is relatively newly built and, as such, has very good insulation properties (double glazed windows etc.). The side effect of this is that there is very little ventilation and therefore humidity rises over […]

In this project we are going to establish a wireless communication between two ESPs and send data from three sensors to an Excel spreadsheet. This tutorial shows a wireless weather station with data logging that you can implement in your home. Before you continue reading this project, please complete the following tutorials: How to get started

Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas etc. Previously we have made a very simple Metal detector without a microcontroller, now we are building the Metal Detector using Arduino. In this project, we are going to use a

Programming is always fun and Arduino is a wonderful platform if you are just getting started with Embedded programming. In this tutorial we will build our own calculator with Arduino. The values can be sent in through a keypad (4×4 keypad) and result can be viewed on a LCD screen (16×2 Dot-matrix). This calculator could

I learnt about Arduino 2 years ago.So I started playing around with simple stuff like LEDs,buttons,motors etc.Then I thought wouldn’t it be cool to connect to do stuff like displaying the day’s weather,stock prices ,train timings on an LCD display.I found that this could be done by sending and receiving data through the internet.So the

In this project, we are going to make a temperature and relative humidity data logger. Arduino is the brain of this project. DHT22 sensor is used for sensing temperature and relative humidity. Arduino Uno is programmed to read temperature, humidity values from DHT22 sensor and save it to a file in an SD Card. So

In this project, we are going to make a Digital Thermometer using Arduino Uno. We will use DS18B20 temperature sensor to sense the temperature and Nokia 5110 LCD to display it. DS18B20 is a 1-Wire digital temperature sensor manufactured by Maxim Integrated and is capable of reporting degree celsius with 9 ~ 12 bit precision.

In my previous Instructable I have described how to plug the ESP-01 module into a breadboard. This is just the first step to make a cheap Arduino WiFi shield using the ESP8266 module. With few more electronic components and the WiFiEsp library you can build it for less that 10 USD. Step 1: Components Here

Story This is a simple tutorial to create an EMF detector. You can use Arduino for this job, but is better use a microcontroller called Attiny85. It is possible program it throe the Arduino interface. What is a Magnetic Field [from Wikipedia] An electromagnetic field (also EMF or EM field) is a physical field produced
ATtiny85 EMF Detector Continue Reading
Story The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended to be used as a cell phone screen. This one is mounted on an easy to solder PCB. It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is a
