DS3231 RTC Module

This module is very useful if you want to create project with time related data such as data logging, alarm and clock. This module keep track the time even the system has been turned off. Thanks to small coin battery installed on this module. Once it has been set, module will keep track the time as long as battery is still life.

There are many libraries that can be used for this module. But here the simple one we will use. Let start to configure it. This module use I2C interface, so you can use it in parallel with other I2C module.

Wiring:

GND <----> GND
VCC <----> 5V
SDA <----> A4(analog pin 4)
SCL <----> A5(analog pin 5)

Libraries:

Download : http://www.rinkydinkelectronics.com/library.php?id=73, or modified version https://github.com/satujamsaja/Arduino/tree/master/ds3231

Sketch:

Download sketch : https://github.com/satujamsaja/Arduino/tree/master/ds3231

Result:

I have also created simple oled clock using this RTC module and oled library downloaded from: http://rinkydinkelectronics.com/library.php?id=79 or the modified library and sketch here: https://github.com/satujamsaja/Arduino/tree/master/ds3231oledi2c

Result:

Good luck.

Using LCD 2004a I2C on project with Arduino

On previous post measurement sensor results displayed on serial monitor. This is good when we are on development stage. When we want something more independent we need external display. I have purchased a few type of display. For now we will use LCD 2004 for external display.

Arduino : Controlling PL9823-F8 RGB LED

I have great passion about electronics since I was in middle school then high school. With some of my school friend that has same passion in electronics, we built radio transmitter so we can communicate each other at anytime. It was so cool back then. Thats why I took study on electrical Engineering. Instead of working on Electrical engineering field, I end up become web programmer. Something I found interesting when i was in college. That's old story. But lately I get bored and try to get another hobby. I have many hobbies and creating electronics stuff is one of it. So I bought my self Arduino Uno and few electronic components to get started learning Arduino programming. So my first project is controlling RGB Led. Here what you need: Arduino Uno with usb data cable and Arduino IDE Install Adafruit Neopixel library 3 PL9823 RGB led Breadboard Jumper cables (mostly male to male) First you need to install Arduino IDE. You can download it here . That would depend

Read temperature and barometric pressure from GY BMP 280 using Arduino

This sensor based on BMP 280 digital pressure sensor made by Bosch. You can find the complete datasheet here . This small sensor is quite impressive with it's accuracy. It claimed to be ±1 hPa in measuring barometric pressure, ±1.0°C in temperature measurement and ±1 meter in altitude accuracy. Pretty impressive right ?
