If you use interrupts, the overhead is about 20 or so ticks, or just over 1us. That gives you the minimum. If polling, and you are lucky, 1 tick is all it takes. 1 /16th of a us.

It should be around 4 to 5V, and not higher than 5V (for a high). It also should not go negative. Something like this will protect the input pin: Warning - audio from an audio jack will be AC and it will go negative. bishop reed boston catholic tv

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 ... As you can see, the original waveform is far from ideal. The height of the steps is irregular because even at 1 %, the R2R resistors are not accurate enough. The poor 8-bit resolution and low ... WebYou can use a delay of 5 sec in your main, or what's even better is to use millis (). Check the blink Arduino program for an example. – Michel Keijzers. Apr 11, 2024 at 22:39. delaying 5 sec in my main would cause a delay in the monitored value. I want the sensed temperature to be accurate with time and as well as the interrupt to stay about ... 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 … bishop referendum consultant nj
