Arduino Uno Menu Template


PaulSS @ instructables.com shows us  how to build a menu for a LCD/button shield:

While working on a new Instructable (coming soon) I had decided to use an Arduino Uno with an LCD/button shield I purchased off of AliExpress. It’s a knockoff of the DFRobot Shield. I knew that I needed a menu for my project but was becoming so disillusioned with the terrible menu template programs available for the Arduino Uno. Many of which were not designed to work with this shield. I decided to make my own.

DIY Voltmeter using a simple voltage sensor and Arduino Uno and a Nokia 5110 LCD

In this video we are going to learn how to build our own voltmeter using a very inexpensive sensor. The voltage we measure is then displayed in a Nokia 5110 LCD display. This project is very easy to build and great learning experience.

With this project we can measure the voltage of our voltage sources, or monitor the battery level of our projects. Let’s see the project in action. I have connected two wires to the voltage sensor module I am using today. I place the red wire to the positive terminal of an AA battery and the black wire to the negative terminal of the battery. In the display we get its voltage. Let’s now try this 18650 battery, we get 3.6V. Let’s now measure this big 12V battery. The voltage is 12.2V. If we compare the readings with a Multimeter, we can see that the measurements are really close! The project is working fine. But be careful, the maximum input voltage that this sensor can measure is 25V, so if you exceed it, you are going to burn your Arduino Pin. Let’s now see how to build this project.

3.5″ Color TFT display ILI9481 on Arduino Uno and Mega

In this video we learn how to drive the new, low cost big, 3.5″ Color TFT display for Arduino Uno and Mega.

A few weeks ago, I discovered this promising new display on Banggood.com and thought that it might be useful in some of our projects. The price of the display is very low for such a big display, it costs 10$ and banggood.com was kind enough to send me a sample unit in order to test it and share my opinion about it with you.

DIY 32ch FPV 5.8ghz LCD


Spikey made his own DIY 32ch FPV 5.8ghz LCD. He writes:

If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on the market now.

Hacking home weather station transmitter


Bob hacked a home weather station transmitter and made a home thermometer from it. He writes:

Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life.

Display YouTube Stats on LCD Screen


In this guide “padeath” shows us how to use a 320×240 LCD display with Arduino UNO to display youtube statistics. The stats are updated once in a minute using the google API.

This little Instructable will show you how to use a 320×240 pixel LCD screen connected to an Arduino Uno with a network shield too, to show stats for Youtube channels.

I created this as I wanted to see how many subscribers and views I had on my channels without having to check Youtube 🙂 The stats update on the LCD screen every minute using the google api.

Arduino Body Thermometer + LCD I2C


This is a body thermometer using a thermistor sensor, Arduino and LCD display.

I’ve decided to provide a funny Arduino concept thermometer in case its the middle of the night, pharmacies are not working, you are not feeling well and you want to check your body temperature. If you have Arduino by your side, this is a life saver!

Mini Arduino Lux Meter


Here is a nice build of a LUX meter using BH1750 sensor and a Nokia 5110 LCD. The meter is controlled by an Arduino Pro Mini and is powered by a Li-Ion battery. The LCD backlight is controlled according to environment light and there is graphing capability of the measured light intensity.

That’s when I realized that I had an unused BH1750 light meter module laying around, which I bought some time ago but never used it. So I grabbed an Arduino, a Nokia 5110 LCD, wired everything up on a breadboard and had a functioning lux meter within a few hours. To make it a bit more fancy, I added some graphing functionality and made the LCD backlight switch on/off depending on the light level.

Real time clock and temperature monitor with a DS3231 and a Color TFT

In this video educ8s.tv is building a Real Time clock and temperature monitor with a big 3.2″ Color TFT display. They are using a DS3231 Real Time clock module to get the time, the date and the temperature. The heart of the project is the powerful Arduino Due board, which can drive the display and update it without any visible flickering at all! Impressive. Let’s start!

A few weeks ago, I tested this 3.2” color TFT display for Arduino with both Arduino Mega and Due. The display works fine and I built a simple project with it. It is a temperature monitor and a real time clock. As you can see at the top, we can see the current date and time, we can see the temperature right now, and at the bottom the Arduino records the minimum and the maximum temperature that it has measured. I also tried to design a basic user interface just with simple shapes. As you can see everything works fine, and it is a very easy and useful project to build. Let’s see how to do it!

ECG Arduino Shield


This project is an Arduino shield able to measure ECG and respiration. The shield is equipped with a LCD display to show measured signal in real time. It’s based on ADS1292R ECG Front End from TI.

Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. Big advantage of this shield is possibility to make it easily at home. The shield is equipped by display to show you measured signal real-time.
