Controlling the AK-DS1307 RTC from Java (SE) on a Raspberry Pi
Thanks to Laurence Vanhelsuwe, of Software Pearls, for submitting this article.
One of the nit-picking criticisms the Raspberry Pi boards get, is that they do not have an on-board real-time clock. When the power is switched off, those poor Raspberries forget what time and day it is.
Enabling the I2C on the Raspberry Pi
In this quick tutorial we’ll enable the I2C bus on the Raspberry Pi.
By default the Raspberry Pi comes with the I2C channel disabled. In order to enable it we have two options: enable it “on-demand” or enable it by modifying some configuration files so it’s enabled by default at every start-up.
About LEDs
LEDs are everywhere. From your keyboard to remote controls. Initially used for indication purposes, now we can see them on big wall screens or illuminating entire rooms. In this quick guide you’ll learn the basics about LEDs and some tips and tricks. Read more →
Controlling the AK-Mr.Wood-L from Java (SE) on a Raspberry Pi
Thanks to Laurence Vanhelsuwe, of Software Pearls, for submitting this article.
We’ve seen how to drive one or more AK-Mr.Wood-L modules via an Arduino, but not everyone uses Arduinos; another very popular development platform today is the Raspberry Pi.
New Products – Components and Moar LEDs
Welcome back to another “New Products” post. This time we have some LEDs and prototyping components.
AK-3232 Usage Guide
This guide shortly explains how to use the AK-3232 Level Converter. Let’s start with the basics:
Why do I need a RS232 Level Converter?
In general, you need a RS232 Level Converter when connecting the UART of a TTL device (for example, the serial port of your microprocessor) to a standard RS232 serial port of, for example, a PC.
New Products – a Little Bit of Everything
Hello and welcome back. This time we have two new breakout boards and some prototyping tools.
New Products – Boards, LEDs & Prototyping
We have some new products, and with these we surpass the +100 products in the catalog. Thank you. We can’t thank our customers enough.

This time we got some sensor boards. These were missing in our catalog and some of you have asked for them, so here they are.
AK-Mr.Wood-L – Library for Arduino
In this guide we are going to explain how to install and how to use the AK-Mr.Wood-L Library for Arduino. This library contains quick access to common tasks when using a shift register with 7-segment displays. It’s based mostly on the standard shiftOut() function. The library contains a predefined ASCII table for all printable characters and numbers.
