+  * There is a bug in the code:
+  * SoftwareSerial softSerial(3, 2); // RX, TX
+  * should be
+  * SoftwareSerial softSerial(2, 3); // RX, TX
+  * Also the suggested baud rate of 9600 doesnt seem to work, adjust to 115200 and go from there. Once you get a receiving signal, run the following to adjust the 01's baud to 9600:
+  * AT+UART_DEF=9600,8,1,0,0
+  * After this, reflash your nano with serial bauds set to 9600 and you should be able to send AT commands over your Nano to the ESP-01 via 9600 baud
