Hil William, this works for me on windows 10 with a LoLin nodemcu v3. Upload Firmata EchoString example with arduino ide. Push Reset on the nodemcu. firmata := Firmata new connectOnPort: 'COM3' baudRate: 57600. firmata inspect Sadly, I can not close and repoen the SerialPort, I have to close and reopen the pharo image first.

I have been unsuccessful in using an Arduino board with Pharo 6.1(32bit) and the Firmata package.
The board is an Arduino Uno clone (ELEGOO UNO R3). The board appears to work fine with the Arduino IDE, which was tested with the BLINK program. The Standard Firmata Library appears to have been successfully uploaded to the board using the Arduino IDE.
COM ports have been closed using
SerialPort allInstancesDo: [:port|port close].
On Windows 10, SerialPort inspect shows that ports are closed. However, firmata := Firmata onPort: âCOM3â baudRate: 576000 failed due to failure to open COM3. The serial port name was obtained from the Arduino IDE Tools menu. The board choice was âArduino Unoâ.
Was the Arduino IDE closed before you started Pharo? Or further, try Pharo immediately after booting your PC.
cheers -ben
