It need to install MFRC522 library. See Arduino - RFID/NFC RC522 tutorialArduino Code - Multiple RFID/NFC Tags We can allow multiple RFID/NFC tags to activate the relay. The below code uses two tags as an example. /* * Created by ArduinoGetStarted.com * * This example code is...
Actually, it's two boards, the Arduino Uno R4 Minima and the Arduino Uno R4 WiFi. These boards are 5-volt logic devices and are physically compatible with the older Arduino Uno R3 boards, preserving your investment in shields and prototyping equipment. In addition, they offer many new ...
The libraries CAN, Servo, and RotaryEncoder are not supported for ESP32 board. Example: a = arduino('COM9','Uno','Libraries','spi') limits the environment to the SPI library. Example: a = arduino('COM9','Uno','Libraries','Adafruit/MotorShieldV2') limits the environment to the Adafru...
Most M-Bus devices should be supported. Tested at ESPs, Arduino MKR and Uno R4. Live test of theMBusinoLib Exampleat wokwi.com A working M-Bus --> MQTT gateway with this libraryMBusino Credits MBusinoLibbased at the AllWize/mbus-payload library but with much more decode capabilities....
The ACAN2517FD library handles the MCP2517FD CAN Controller, in CAN FD mode. The library supports the 4MHz, 20 MHz and 40 MHz oscillator clock. The driver supports many bit rates: the CAN bit timing calculator finds settings for standard 62.5 kbit/s, 125 kbit/s, 250 kbit/s, 500 kbit...
It integrates RS-485, CAN bus, Ethernet, Wi-Fi, Bluetooth, and RTC, and supports expansion via a PCIe slot for 4G LTE cellular communication, making it suitable for automation, environmental monitoring, and remote data acquisition in industrial or outdoor settings. The IoT controller also ...
The Raspberry Pi is a microcomputer with a micro price. But don’t be fooled by its size, it packs a powerful punch!. Media Center, Home Control, Robotics, or Desktop Replacement – you can do it all with the Raspberry Pi. Read more ...
