    Why do electrical engineering students have to study computer programming

    I think it depends which area of electrical engineering you want to concentrate on. Let's say that you are interested in solid state devices, then you might not ever use traditional HLLs like C or python, but you would definitely need good programming skills with mathematical software like...

    Antennas for Tx433/RX433

    HI, I am using tx433/Rx433 RF modules to transfer some data between two AVRs. I know that we have to use 30-35 cm simple wires as antennas. I send out out two bytes. The second byte is the actual data , and first byte is to get rid of unwanted information. However, I have a hard time...

    DS18S20 with Atmega16

    Thank's a lot! Turns out I was using bottom view as top view and messed up Vcc and ground pins. It works fine now. I am surprised the chip didn't blow up.

    DS18S20 with Atmega16

    Hi, I checked the resistor to make sure it was 4.7kohms. So, if Vdd pin is connected to 5v and ground pin to ground , the data pin (center pin) has voltage of ~5v ( after disconnecting the resistor). Does it mean the chip is bad?

    Analog to digital conversion for a project

    This sounds interesting. So I am trying to use as few digital components as possible just as a challenge. Do you think it would work if I used R2R ladder instead of DAC ( the problem I run in there is that apparently: "On a printed circuit...

    Analog to digital conversion for a project

    Hey guys, I am trying to do analog to digital conversion for a project. I don't want to use the digital chip, but want to do it in analog. I need 8-bit resolution. I found one approach: string resistor ladder. It uses 2^n-1 resistors. For 8-bit conversion I will have to use 255 resistors...

    Electrical Engineering Senior Design Project Ideas

    Software Defined Radio would be a good project. You can easily finish it off in a term. In case you have time left you can add a lot of extra features for "wow" factor. Typically you can use FPGA and write software in C or VHDL. You can also use a DSP if you can get hold of the fast enough. I...
