The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. Serial.Arduino Uno is a microcontroller board based on the ATmega328P ( datasheet). Void printTemperature(DeviceAddress deviceAddress)įloat tempC = sensors. Void printAddress(DeviceAddress deviceAddress) Pass our oneWire reference to Dallas Temperature. Setup a oneWire instance to communicate with any OneWire devices #include // Data wire is plugged into port 2 on the Arduino It is recommended that you connect only one sensor at a time so that you can find each sensor’s address and assign it a name. The sketch below detects all DS18B20s on the bus and prints their one-wire addresses on the serial monitor. Finding the Addresses of DS18B20s on a Bus So we’ll use one sketch to find and record the address of each sensor, and then another sketch to read each sensor individually. print(DallasTemperature:: toFahrenheit(tempC)) Įach DS18B20 is programmed with a unique 64-bit address at the time of manufacture, allowing them to be distinguished from one another. print(( char) 176) //shows degrees character Display temperature from each sensor for ( int i = 0 i < deviceCount i++) Send command to all the sensors for temperature conversion Pass oneWire reference to DallasTemperature library Setup a oneWire instance to communicate with any OneWire device #include // Data wire is plugged into digital pin 2 on the Arduino
