If the value received is 512, the voltage value will be around 2.5V. This range is mapped to the voltage of the pin (normally 0 to 5V). Analog reading is of 10-bit resolution, hence the range of value is 0 to 1023. This block returns the value of analog pins available in evive. To read analog input from an analog pin in Scratch, you have to use the read analog pin () block, available in the evive extension. } How to use Analog Pin in PictoBlox (Scratch) put your main code here, to run repeatedly:ĭigitalWrite(LEDPin, HIGH) // sets the LED on (5V on pin 13)ĭigitalWrite(LEDPin, LOW) // sets the LED off (0V on pin 13) put your setup code here, to run once: Int val // variable to store the read value\ Int PotPin = A9 // Potentiometer connected to analog pin A9 Int LEDPin = 13 // LED connected to digital pin 13 Of the potentiometer 1 of evive, the delay between the change of state This code demonstrate the use of analogRead(). the values of the other analog inputs, how close your hand is to the board, etc.). Note: If the analog input pin is not connected to anything, the value returned by analogRead() will fluctuate based on a number of factors (e.g. It takes about 112 microseconds (0.000112 s) to read an analog input, so the maximum reading rate is about 9,000 times a second. This yields a resolution between readings of 5 volts / 1024 units or. The output is an integer value between (Due to a 10-bit analog to digital converter), which is mapped between 0 and 5 volts input voltage. To read analog input from an analog pin in Arduino IDE, you have to use analogRead(pin) function.ĪnalogRead(pin) function reads the value from the specific analog pin. VVR_Voltage_Sense (for sensing variable voltage output – A8).VSS_Voltage_Sense (for sensing input voltage – A7).Two potentiometers: Potentiometer_1 (A9), Potentiometer_2 (A10).10 analog pins are available for the user, A0 to A5 & A12 to A15.For example, the code would look like this to set analog pin 0 to an output, and to set it HIGH. The analog pins can be used identically to the digital pins, using the aliases A0 (for analog input 0), A1, etc. While the main function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of General Purpose Input/Output (GPIO) pins (the same as digital pins 0 – 13). The converter has 10-bit resolution, returning integers from 0 to 1023. Out of these, only 10 analog inputs are available to the user. The Atmega controllers used for evive contain a total of 16 channel analog-to-digital (A/D) converters. Evive has 10 analog input pins behind Magic Lid. ![]()
