The device supports only 9600baud. So you will need to wire a USB driver specific to this device to make it work for USB (It might be easier to use the regular Serial port). Also, you might need some line/port drivers to connect this to the port.
This should be possible using any programming...
IEEE student membership is not free... but it comes at a lower price...
Here are the details: https://www.ieee.org/membership_services/membership/join/join_dues.html
Instead of the default regulator in the adapter try using a 7805 based one... it can source up to 1A... http://www.fairchildsemi.com/pf/LM/LM7805.html or **broken link removed**
Re: Monostable IC555-based Morse pulse generator help/questi
A monostable around 555 should work... But how are you going to tx dots and dashes (3 times the dot) for Morse code... you may need another RC for that as well.
Also refer to the data sheet before wiring up for any mistakes (they...
The simplest solution will be to put an IR LED with a proper beam (you might need to cover the sides so that no direct beam falls in the sensor) and an IR sensor. use an op-amp to compare the sensor output to a reference voltage and give out a high voltage (logic 1; for opamp it should be the...
Re: dtmf over pmr radio
Looks like it might just be a simple phase shift... Is should not affect decoding (or I am missing something)! Try increasing the pulse length so that the decoder can decode it better...
Just a silly check.. you are ac coupling the signal input to the decoder using a...
Re: Optical Heart Rate Monitor: Can I use a fourier transfor
An FFT should work at least in theory...
But a better approach will be to use a Schmitt Trigger at the sensor output and use a counter to count the pulses... FFT is an overkill for the purpose!
For that the digital chips inside should also support the higher frequencies... If it supports that, you might have to change the input clocks as well in addition to all that you mentioned.
Re: a/d input to monitor motor batteries' voltage and adjust
Can't you use a high impedance potential divider scale down the 6V battery voltage? Since the output will be directly proportional to the battery voltage, your purpose will be served!
