I am new to microelectronic.But I have a little knowledge in some hobby circuits etc.

I want to make a fully automated circuit for my vehicle,by using a short range RFID sensor for detecting the unique person(Driver) for driving a vehicle,-So as to avoid anyone driving my vehicle..

My idea is..

bike project details

program description

  • When the owner sit on his vehicle and put the key on vehicle.
  • RFID sensor start detecting necessary tags.
  • If necessary tag found detected, vehicle will turn on
  • If no necessary tags found,inform the owner with some voice alert

Advantage is that

no one can ride our bike without necessary RFID tag(Because No one knows about our personal RFID tag).

This is the first step.

Is it possible to create a micro-controller program using high-level programs like JAVA or VB etc and convert to hexadecimal codes,for my MC??.

Thanks in advance..

  • \$\begingroup\$ No... Rather not advised to use so.... Prefer C for programming on Microcontroller or you can use Arduino or raspberry pi which comes with lot of libraries and easy if you don't know much about Embedded programming \$\endgroup\$ – Swanand Sep 19 '15 at 18:26
  • \$\begingroup\$ @Swanand, I am also a programmer,But I don't know much about embeded C. \$\endgroup\$ – user86790 Sep 20 '15 at 4:56
  • \$\begingroup\$ That's why I suggested Arduino or raspberry pi \$\endgroup\$ – Swanand Sep 21 '15 at 6:09

I regard this as a too serious project for a beginner, since you're meddling with something that needs reliable operation - with little experience you might leave critical bugs in your code which would leave you with a mild annoyance at best or a damaged vehicle at worst.

To answer your original question:

You could program it in a high level language, however that would defeat the purpose of a microcontroller, because you'd be using it's resources very wastefully. If you really want a high level language, you can just plop a Raspberry Pi, or a Carambola2 unit in there.

If you desperately want to go for a high level language, you could go for an Espruino, however javascript is quite similar to C/C++, so why not just go for the true way of coding microcontrollers immediately?

I'd recommend trying an Arduino, since it'd have all the modules you'd need easily available as well as a rich array of drivers/libraries already written for said modules. This would mean that you would have to study the C language a bit, however it's nothing too difficult if you need just a simple application to recognise a specific hex stream from an RFID reader and switch output pins accordingly.

  • \$\begingroup\$ ,Thanks for your kind reply. I completed Diploma in computer eng:-obviously I know programs like C,C++,java,java script like that.But I don't know much about embedded C.Please give me a sample program with example. \$\endgroup\$ – user86790 Sep 20 '15 at 4:53
  • \$\begingroup\$ Here's a simple Arduino based example: playground.arduino.cc/Learning/PRFID And here's a more serious write-up with code which doesn't rely on the Arduino libraries: courses.cit.cornell.edu/ee476/FinalProjects/s2006/cjr37/Website/… \$\endgroup\$ – Linards Sep 20 '15 at 20:58
