Designing The Parts V – AT24C64

Designing The Parts V – AT24C64

Following the same way that we did with the previous articles, we now have to design the component AT24C64, which is an EEPROM memory. This time, I didn’t find any component like that on Sparkfun’s or Adafruit’s library. This time you really might need to draw the component!

Designing The Parts IV – PCF8563

Following the same way that we did with the previous articles, we now have to design the component PCF8563, which is a real-time clock module. This time, I didn’t find any component like that on Sparkfun’s or Adafruit’s library. This time you really might need to draw the component!

Designing The Parts I – MPU6050

Designing The Parts I – MPU6050

After installing EAGLE from CadSoft, you may want to open some of the examples that come with the software. But, to begin our project, the user needs to have the components inside the library. You can use the Adafruit library, or you can make your own. If you don’t trust the library, you can always design your own part. Besides, even if you use the component from the library, you can always practice and learn.

Installing And Setting Up Eagle

This tutorial is the first in a series to help people follow my Arduino articles, and go from scratch to finnish the Arduino Powered Smartwatch. What is written on this article, however, can be found on many other websites, but I wanted to make the complete series of tutorials to cover all aspects of the project. So if you already know this, skip this page, because it might seem a little redundant. If not, I hope this helps you in some way.

IoT WiFi DIY motion detector with e-mail notification using PIR sensor and ESP8266

In this project I am using the ESP8266 WiFi module and PIR sensor motion detector to get e-mail alerts if someone enters the room while I am away. I am using GadgetKeeper Cloud Platform to bring e-mail notifications with PIR Sensor. I have choose GadgetKeeper Cloud Platform because it’s FREE and easy to use. The whole project costed me around $7 and was pretty easy to build.

Step 1: Parts

  • 1× esp8266-07 – Ebay;
  • 1× PIR Sensor – Ebay;
  • 1x Bread Board Power Supply – Ebay;
  • 1x 12V AC-DC Power Adaptor – Ebay;
  • 2x 400pin Breadboard – Ebay;
  • Wires.

Arduino Power-down Mode With Accelerometer, Compass and Pressure Sensor

Arduino Power-down Mode With Accelerometer, Compass and Pressure Sensor

Introduction

Last article, I wrote about how to use our own homemade Arduino Pro Mini bare bones along with an OLED display and how to make both of them consume as little power as possible. In fact, we managed to achieve a small 1.1 uA current with both of them sleeping. Also in our circuit there were a PCF8563 real-time clock module and one AT24C64 EEPROM memory. Now, to proceed with our smartwatch project we need to add sensors, such as an accelerometer, compass and pressure sensor. This article is about how to add them, read the variables and keep saving power.

OLED Display and Arduino With Power-Save Mode

OLED Display and Arduino With Power-Save Mode

On the previous article I wrote about how to use the real-time clock module with the EEPROM non-volatile memory. Now it is time to get something working that resembles a watch. Make something that matters. How about adding a display? Last post it was possible to achieve a power consumption of only 16 uA (improved) 0.7uA on the smartwatch prototype. Now we can see how much power the watch will consume. In this case, it is an application that needs to consume the smallest current possible but also needs a display, then one can use a OLED display, which is the abbreviation of “Organic Light-Emitting Diode”, which is a much more economic display in terms of current than the regular LED displays. An overview about OLEDs, first.
