This just came to my mind.
Although it isnt possible to use a USB dongle with the Microcontroller (because of the driver and BT stack implementation) but what about breaking open an old bluetooth wireless mouse and using the module inside it ?
I think these wireless bluetooth mice use...
Bringing up this old thread once again.
This was almost impossible so many years ago is it still so ? making an ordinary bluetooth dongle work with a microcontroller.
I am very interested in this implementation of yours, this is the only post I found which says that this was done. I cracked...
These 2 also came to my mind but the issue is that how will they connect to the mobile ? I want to have the ease of just picking up the mobile phone, launching an app and simply pushing a button to control the lights. I dont want to connect any wire to the mobile phone because that will defeat...
Hi,
I am thinking of making a home automation system in which lights and fans in the whole house are controlled directly through an android application. Basically the flow will be something as follows:
Bulb----Relay-------------Patch Panel --------Microcontroller ----Wireless Module 1...
AVR Development Board, where to get one and which one
I used to be a hobbyist and an enthusiast in electronics during my student days, made many DIY projects and participated in a few exhibitions and contests even but somehow I couldnt continue my hobby in my professional life. Now after a few...
Re: AVR programmer
You can also try making your own programmer. All you need is a DB-25 parallel port connector and some other basic components. You can find alot of circuit diagrams for making your own programmer. Just search Goolgle!
I made my own ISP, parallel port programmer, a couple of...
For a project of mine , I have decided to use the Motorolla microcontroller
DSP56F807
https://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=DSP56F807&fsrch=1
It is a 16 bit hybrid controller which has DSP and microcontroller functionalities.
I wanted to ask that are there other...
The way I see it you only need a serial port to interface with your GSM module.
For the keypad you can use any IO ports of the microcontroller.
So not only can you use the AVR ATMega32 but you can also use your AT89C51 because both of them have a serial port and IO ports !!!
I am doing a project in which I need to step down DC Voltage (0 to 60V) by a factor of 6.
For example if input voltage is 36.36V then on the output of the IC I should get 6.06 volts.
Is there any IC which can do that for me ?
If there is no IC then is there any small circuit for doing this ?
Re: mbf200
Can anyone who has worked on this sensor please give me the circuit diagram to run the mbf200?
I cant detect any signs of life in the sensor.
Also how would i know that the sensor is alive?
I will be happy to donate a good amount of points to the person who is generous enough to...
fujitsu fingerprint sensor tutorial
Can u please post your initialization code? What values did u for DTR and DCR etc in your finalised code?
Also how can you tell that the sensor has been initialized correctly ?
I am trying to interface a mbf200 fingerprint sensor with the ATMEGA32 AVR microcontroller using the parallel bus interface of the microcontroller.
I am having problems with the sensor initialization.
First thing I want to know is that how will i know that the sensor has been initialized...
