Arduino uno - What is Serial.begin9600? - Arduino Stack Exchange We'll use the shield again but for now, we can examine the RX and TX LEDs on the main Arduino board which will help you with debugging Libraries are great places, and not yet illegal in the United States! Arduino Serial Reference. Not to diminish or disrespect @Nick-Gammon's excellent coverage of this topic.

SoftwareSerial.write - Arduino The shield doesn't contain any programs or data, it is just our way of connecing up the LEDs and resistors. SoftwareSerial writedata. Description. Prints data to the transmit pin of the software serial port as raw bytes. Works the same as the Serial.write function.

Arduino Serial write - Stack Overflow The Esp8266 is a 3.3v device and so I am using a voltage divider to bring the Arduinos 5V down to 3.3v. The output is correct. You are writing data, but you are trying to see them as ASCII, that's why you see for example } instead of 125.

Serial.print or serial.write? - Arduino Forum The 5V Arduino will read 3.3v as HH so you can connect the ESP8266 TX pin directly to the Arduino RX pin.
