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!

Using Low Cost Hardware to Enhance the User Experience

FT810CB-HY50HD-2

Ken Boak discuss how to build a graphic user interface using cheap TFT toughscreen displays. This article is about using their lowcost graphics co-processor IC to provide a neat user interface for any low-end microcontroller.

These days, when you can buy a 7″ tablet for $50, there is all the more reason for makers and hackers to want to become more engaged with up to the minute 7″ touchscreen technology for their latest projects. Fortunately, recent developments in hardware have made this both affordable and easy to do – to the point where no project is too small, not have a neat touchscreen interface – and sound too!

Arduino Analog Signal Graphing on a TFT

FEVSJRTIKCX9R5P.MEDIUM

dmainmon @ instructables.com has build an analog signal graphing project using Arduino Mega 2560 and a 2.8 TFT display. This project is used to display two analog signals as line and bar graphs. Touching the screen pauses the graph and opens a menu to adjust setting for the graphs.

The project uses an Arduino Mega 2560 and UNO R3 2.8 TFT Touch Screen to display two analog signals as line and bar graphs. One signal is a photo resistor and the second is an audio sample from an Adafruit Electret Microphone Amplifier with Adjustable Gain module. The audio signal is graphically displayed twice; once in the center using a line graph and also on the bottom with a bar graph. The top graph represents the photo resistor signal.

Arduino Controlled Modular Bench Power Supply

Denis @ envox.hr has designed a great PSU that is reliable, modular, programmable and of course Open source. The power supply is controlled by an Arduino and a touchscreen TFT screen is used to monitor and control it. It comes with a bunch of features you can check on the link below.

The programmable bench power supply project was an attempt to create reliable, modular, open and programmable power supply that can be used for various tasks starting with powering breadboard, charge (or to some extent discharge) batteries of various types and sizes or use as a tool in school/educational and science experiments.

Photoplethysmography – IR Heart Rate Monitor

F4ZW3SBIJOMQ3G4.MEDIUM

SteveQuinn @ instructables.com show us how to create a heart rate monitor using an IR phototransistor and Arduino and display the data on a TFT screen.

This Instructable documents how to create a simple heart rate monitor using Photoplethysmography with an IR phototransistor via transmissive absorption using the Arduino to process the pulsatile data and display live results via a TFT screen.

To use the source code and create the necessary circuitry you will need a reasonable grasp of electronics, knowledge of the Arduino, a DMM and some patience.

Arduino Project: Flappy Bird game Clone with a 1.8″ color TFT display (ST7735)

Educ8s.com @ youtube.com:

Playing the Flappy Bird game on Arduino is extremely easy. With a cheap Arduino Uno and a very cheap 1.8″ color TFT display (ST7735) you can enjoy the classic game, the best part? It is going to be a DIY project. Actually you can build your own gaming console using Arduino, like the popular Gamebuino.

The code of the project is by Themistocles Benetatos who shares the code with us. In his blog he describes how he managed to achieve that result. Don’t miss it: http://www.mrt-prodz.com/blog/view/20…

All you have to do is to buy the following parts, if you don’t own them already. The cost is around 10$:

Rui Cabral tipped us with his latest project. He writes:

Lately I’ve been testing a small 2.4″ TFT display PBC ILI9341 with touch and bought on ebay for less than 8euros!

This graphic display is an excellent solution for both small projects and for more advanced projects since it includes SD card connector to access stored images.

This display has a resolution of 240×320 RGB.

S.M.A.R.T. Alarm Clock

by Tony DiCola @ makezine.com:

Wouldn’t it be nice to have an internet-connected alarm clock that automatically sets itself, based on your calendar? You would never miss an early appointment, never forget to set your alarm, and enjoy more restful sleep knowing you’ve solved the nightmare of regulating your alarms. An internet-savvy alarm clock could even watch your inbox and wake you up if friends or family send you an important email.

This S.M.A.R.T. Alarm Clock (Setup for Meetings, Appointments, Reminders, and Tasks) uses the Arduino Yún, which is a special Arduino with two processors. One processor runs an embedded version of Linux and is connected to the internet over wi-fi or Ethernet. The other processor uses the same chip as the Arduino Leonardo microcontroller, allowing the Yún to work with most Arduino shields and accessories. By using the Arduino Yún, this project can talk to complex web services with the Linux processor, and interface with hardware — an LCD touchscreen — on the second processor.
