How many analog comparator pins does the attiny85 have?
The output of their comparison store within the register and can be used further. The analog comparator input pin of ATtiny85 are: ANALOG TO DIGITAL CONVERTER: ATtiny85 has 4 analog input channels. The analog input is converted into 10-bit digital output.
What is the maximum input voltage for attiny85?
Meaning the input Analog signal can be translated to 10 bit data. The maximum analog input voltage to this microcontroller can range from 0V to 5V. Let’s look into the configuration of this ADC in ATtiny85 controller. ADMUX register should be used to configure ADC peripheral in ATtiny85.
How many ADC channels are there in attiny85?
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.
Can a attiny85 be used as a potentiometer?
An ATtiny85 being prototyped out to a potentiometer (analog input), button (digital input), and RGB LED (analog/digital output). Note: The ATtiny85’s I 2 C and SPI functionality cannot be used in this method because the pins are still tied to the SPI pins of the ATtiny84 used to program the chip.
What kind of acoustic output can a piezo ceramic disc produce?
In practice, piezo ceramic disc/element with a cavity encase will produce much higher acoustic output when compared to an ordinary one without the case. According to Chinese web documentation, the piezoceramic disc is also known as “beep film” which is one of the most used piezoelectric ceramics.
How is the input voltage of the attiny85 determined?
ATtiny85 convert the analog data at the 65-260us speed which is enough to keep the system update at every second. Analog input voltage level is decided according to the power supply voltage, which can be some time cause error for external devices.
Which is oscillator does the attiny85 come with?
OSCILLATOR/CLOCK: It comes with an 8MHz internal clock and the value of the clock can be variate from 0-8Mhz but ATtiny85 has the ability to expand the oscillator up to 20MHz. To increase the oscillator value, it should be connected to the oscillator pins of the microcontroller, which are:
