WebThe frequencies used for RFID systems are typically in the range of 125 kHz to 13.56 MHz. To block RFID chips, a device that emits a signal at the same frequency as the RFID system can be used. However, it is important to note that the use of such devices may not be legal in all situations. Can RFID be intercepted? WebSecond, you have to realize that there is additional overhead associated with a call to an interrupt vector. Here is an extract from the ATMega328P datasheet, section 7.7.1 - this should be representative of all AVRs: The interrupt execution response for all the enabled AVR interrupts is four clock cycles minimum.

WebIn this project I used a timer interrupt to output a sine wave of a specific frequency from the Arduino. I soldered a simple 8 bit R2R DAC to digital pins 0-7. This DAC was constructed from 10k and 20k resistors arranged in a multi-leveled voltage divider.. I'll be posting more about the construction of the DAC in another instructable, for now I've included the … WebSince the interrupts occur at such a high frequency, I had to keep the interrupt routine, the piece of code encapsulated in the ISR(TIMER1 ...
