Compatible with the UNO R3 board and Mega 2560 R3. It can turn your Arduino into a simple web server or use the Internet to read /write its digital and analog outputs/inputs. To use other serial ports, you simply change numbers and wire to pins 14>19 accordingly although, if you have that much communication to worry about, you might have been better off using an NRF24 network, which is made for that sort of thing, or even have one bluetooth polling several. keyestudio W5100 Ethernet Shield gives you an easy way to get your Arduino Online.
#KEYESTUDIO ARDUINO MEGA SERIAL PORT MAC CODE#
Your code from Uno should work unchanged on Mega. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB. So it all seems pretty clunky and I doubt it was ever put into practice. Keyestudio Mega 2560 compatible Advanced is a microcontroller board based on the ATMEGA2560-16AU, fully compatible with Keyestudio Mega 2560 R3 board and ARDUINO MEGA 2560 REV3. The Arduino code in your link seems straightforward and advises you in red about having bluetooth disconnected while uploading, but confuses things about the baud rate by specifying 38400 for a monitor you are not using. Having said that, I have never heard of anybody actually frying an HC-0x by feeding it a 5v signal. No matter how many sources there not using the voltage divider, and there are quite a few of them, if you can actually read what is on the back of the board, and can understand the difference between 3.3v and 5v, you might work out that not using a divider is a bad idea.

That guy on Youtube doesn’t know what he is talking about and the reason why Robin2 is confused is because no HC-06 breakout board had on-board conversion for its Rx signal.
