How fast can Arduino ADC sample?
Arduino itself provides a convenient way to read analog input using analogRead() function. Without going into much details, the analogRead() function takes 100 miliseconds leading to a theoretical sampling rate of 9600 Hz (9600 samples each second).
How fast can Arduino read analog input?
about 10,000 times a second
On ATmega based boards (UNO, Nano, Mini, Mega), it takes about 100 microseconds (0.0001 s) to read an analog input, so the maximum reading rate is about 10,000 times a second.
Does ATtiny have ADC?
Analog to Digital Converter ( ADC ) in ATtiny85: There are total of 4 ADC channels present in ATtiny85. These channels are interface to to pins PB2, PB3, PB4, PB5 in port B. Also ATtiny85 ADC is of 10 bit resolution. Meaning the input Analog signal can be translated to 10 bit data.
How fast can Arduino read?
the short answer is: digitalRead() takes 4.9us to execute on a 16MIPS Arduino Uno, or 79 ticks (=instructions). the fastest you can read digitalRead() is then 200KHz (= 1/4.9us).
How does the ADC work on the attiny85?
For example, if the ATtiny85 is powered with 5V and the ADC is configured to use Vcc as the reference voltage then the ADC is able to convert an (analogue) voltage between 0V and 5V. Within the whole range between 0V to 5V it is able to sample any voltage and convert that to an 8-bit (256 values) or 10-bit (1024 values)…
What is the reference voltage of the attiny85?
The reference voltage determines the upper limit of the ADC range. For example, if the ATtiny85 is powered with 5V and the ADC is configured to use Vcc as the reference voltage then the ADC is able to convert an (analogue) voltage between 0V and 5V.
How to get started with the attiny85 microcontroller?
As with many dev boards and chips today, the easiest way to get started with the ATtiny85 is via the Arduino IDE and a programmer. Follow these simple steps: 1. Install the Arduino IDE 2. Navigate to the Arduino IDE ATtiny microcontroller support GitHub page 3. Follow the instructions to add this new feature 4.
How many I / O pins does the attiny85 have?
Once you build a solid foundation of skills, you may want to shrink your project down even more. For simple applications, the ATtiny85 can be a great choice. The chip features five I/O pins, or six if you reprogram the reset pin to function as an extra I/O pin.
