ESP32 I2C Scanner – Arduino Code Example The code example down below does the following: We start with defining initializing the I2C peripheral. And we’ll also initialize a serial UART communication to print back the results to the PC serial terminal (Arduino Monitor). Then, we’ll start ...
Learn about SPI communication protocol with the ESP32 using Arduino IDE. We’ll take a look at the ESP32 SPI pins, how to connect SPI devices, define custom SPI pins, how to use multiple SPI devices, and much more.
voidsetup(){floatmyFloat=1.1234;Serial.begin(9600);Serial.print(myFloat,2);}voidloop(){} Output: 1.12 In this Arduino code, we declare a floating-point variable namedmyFloatand assign it the value1.1234. Then, we initialize the serial communication with a baud rate of9600usingSerial.begin(...
IRreceiver and IRsender object have been added and can be used without defining them, like the well known Arduino Serial object. Just remove the line IRrecv IrReceiver(IR_RECEIVE_PIN); and/or IRsend IrSender; in your program, and replace all occurrences of IRrecv. or irrecv. with Ir...
Finally, re-open your Arduino IDE Getting the DS18B20 Sensor Address Each DS18B20 temperature sensor has a serial number assigned to it. First, you need to find that number to label each sensor accordingly. You need to do this, so that later you know from which sensor you’re reading the...
Building Automation system is a revolution in automation technology based on the Arduino platform. BAS doesn't need any dedicated hardware console and hence this involves in low cost of the system with simple design. This BAS will control the applications based on its time based profile connected...

a unique two in one solution. It can be connected via a UIO stick with the computer to evaluate its features via ConfigWizard (a graphical user interface) which can be found in the Infineon Toolbox. In addition, the evaluation board features an Arduino Shield interface for rapid pro...
ESP8266 ADC - Multiple Analog Sensors: Although the ESP8266 -07 and -12 only have one ADC pin, it doesn't mean that you are limited to only one analog sensor per module. You can use many! However, in order to use multiple sensors you will need to 'multi
