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.

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.
