  • Mini Dual Power Supply
    on Aug 26, 2016 in Projects
    Even if the analog domain is not in my main area of activity, in many cases we are dealing with small signals which can not be used directly by an usual ADC (that we can find in almost any microcontroller these days). For instance: measuring the volt...
  • LCD + 74HC595 Module
    on Jul 19, 2016 in Arduino Projects
    It’s been a while since this idea (to control a LCD module with a shift register) appeared. There are several variants, different registers, different schematics, different libraries. Even if using a shift register to increase the number of dig...
  • AVR 4 Relay Board
    on Jun 6, 2016 in Arduino AVR MCU Projects
    Now we move to a more interesting project. A small(and smart) module with 4 relays, RS232 and RS485 interface. This is a very good example about what can be done with these small hardware projects from this site (open source projects). So. I joined t...
  • Simple Relay Module(s)
    on May 19, 2016 in Arduino AVR MCU Projects
    Even though there are plenty of similar modules on the market I felt the need to design my own relay module. Primarily because I did not have one handy when I needed. And these modules are two months away from me. Secondly because I wanted to test th...

  • RS232TTL Board
    on Apr 14, 2015 in Arduino AVR MCU Projects
    ABOUT PROJECT There is nothing special with this little board. The schematic is standard (from MAX323/MAX232N datasheet). Although there are hundreds of projects that treat this topic, I felt the need to redesign in gEDA. The main reasons are as foll...
  • ATmega 40 pin minimal board
    on Mar 20, 2015 in Arduino AVR MCU Projects
    ABOUT PROJECT After I wrote several articles about using ATmega microcontrollers (DIP40) in Arduino environment (here and at Instructables), I had some feedback that I was asked how to be effectively put into operation this project. As I came into th...
  • Using ATmega16 with Arduino IDE
    on Mar 9, 2015 in Arduino AVR MCU Tutorials
    A few days ago I searched in my microcontrollers box (one of them ) and I came across some ATmega16. I almost forgot I had these microcontrollers there. In recent years I became more involved in using different ATmega microcontrollers with Arduino an...
  • Rotary encoders experiments – part 2
    on Feb 7, 2015 in Arduino AVR MCU Projects
    Here is the second article of the series about reading rotary encoders. In this section we will explore reading of 15 rotary encoders  with Atmega1284 and Arduino IDE. 15 is the maximum of encoders that can be connected to the microcontroller, consi...
