Why arduino is slow ?

Is Arduino really slow ? Well that is really relative, as like everything else.  I am not talking about Time Dilation and space time fabric bending stuff here.  Alas! I haven’t seen Interstellar yet.  Anyways, this post is really about how arduino performs the basics of its function and how it appears a little slow […]

Logic "Analysing" Serial Communication

Lets hit it directly, assuming you are already familiar with Serial Communication.  You might have used it already with Arduino or other microcontrollers, almost all of them are equipped with the UART/USART module. Serial Communication  — just in case you need a little brushing up. The pic shown above is taken from WiKi, above link. […]

Logic Analyser (Saleae) : Getting Started

Yeah, “Tear in the Eyes” moment, whenever I get a new electronics item to play with.  This time I got my hands on Saleae Logic Analyser (digital one though). This one allows you to probe 8 digital channels simultaneously.  The device is extremely simple to use for first timers.   Just plug a miniUSB cable, […]

Programming the programmer : AVR

Well, as the name says it all, this post is indeed all about programming mumbo jumbo of AVRs.  First lets get the picture as it is normally seen. C/C++ Code ->Compiler->linker(&/|)loader->avr-objcopy->hex file->avrdude->running program. So, the above order seems simple enough but every stage is a big process in itself.   What I in this post […]

FTDI plays Dirty : Drivers Scandal

Woahh!! feeling like “No!! Not this” or “Nice move there”. You can be one of the two people saying above lines by the action taken by FTDI . So, What is FTDI ?  [[Those who already know skip Down to “Driver Scandal”.  ]]    FTDI is actually a company that manufactures chips and electronics solutions mostly […]

Intel HEX for AVR explained

Ughhh! It really took me 2 days to understand the whole picture here.  We all know that there is a hex file generated by the “Compiler” or the Arduino IDE (lets just say it now..allow me to use loose terms here, gotta explain a little below) and that HEX file is uploaded into the controller and […]

Working with RC and Arduino: Part 1

Working with RC and Arduino: Part 1

The HK-T6A V2 is a classic 6-channel RC Transmitter, best option for starters. The 4 channels are used for flying while rest 2 can be used for landing purposes. It is programmable as well. For that purpose one need to have the programming cable. It requires 12 V as the optimum voltage supply level. However, […]

GUI: Plug n Play Duino

GUI: Plug n Play Duino

The main idea behind the “Plug n Play Duino” model was the ease of implementation of algorithms of line following, edge avoiding and all such sort of works… or “To make it a toy”(in english :P) As Saurabh gave a detailed list of features of this board here, http://www.embedded4fun.com/plug-n-play-du…a-new-approach/ We built a GUI for this […]

Rotary Encoder

Rotary Encoder

Basically, Rotary Encoder converts the angular motion of wheel or shaft intoanalog or digital codes, and by codes we can count the number of rotations of the same. That seems pretty simple. 😛 First thing one faces in robotics, is the motion update of the bot. This motion update requires the tracking of the number […]
