Note: To use the UART pins on the main board when attached to the extension board, connect a 2.54mm pitch jumper to pin 1 and 2 on JP10 of the extension board to disable the extension board UART. For more detail

Because default pins of UART1 such as GPIO9 and GPIO10 are internally connected to the SPI flash memory. Also, on some ESP32 boards, they are even exposed on the pinout headers. Hence, we can not use UART2 directly without reassigning pins in Arduino IDE. UART PortRxTxUseable UART0 ...
So I try to shift the number to the right with 4 bits to save the first 8 bits, then I apply a mask to save the last 4 bits. I transmit these 2 uint8_t variables via UART and I try to reassemble the number in Arduino like this: These are the values from Arduino: What is ...

Where to Use ARDUINO PRO MINI All the ARDUINO boards are popular because of ease of understanding and application. Also, the ARDUINO is an open source platform where one can get all related data and original module schematics. In this platform, one can customize the system depending on the ne...
For UART to work, both the transmitter and receiver need to have same configurations: baud rate, start, stop and parity bit. HC-05's default setting is typically the same as Arduino's default setting, so most times you do not need to worry about configuration, if you use 9600 as the ...
Why use the CAN protocol rather than UART, SPI, and I2C? Compared to other communication protocols like UART, SPI, and I2C, using the CAN protocol ismuch more reliableas they arestandard automotive communication protocolsthat are used to transmit vital data like a throttle position in a vehicl...
Seeed Studio has a variety of sensors and devices that can use this I2C or UART connection. With our Grove Connectors, you can easily plug-in modules with Arduino without any soldering or jumper systems. We will elaborate more about Grove later in our Sensors and shields section. ...
Use the green Wire to connect the SDA from the UART to the SDA on the Arduino And finally use the yellow wire to connect the SCL from the UART to the SCL on the Arduino NOTE: The SDA and SCL PINS on the Arduino are labeled on the back of the board, use the pictures as guidelines...
