In unit 1, page 42, I am not able to get the led to blink using the esp-01 board. The arduino ide seems to load the code correctly using a serial adapter, (compiles and then writes, ending with
"Leaving... Hard resetting via RTS pin
but when I connect the esp-01 to the circuit on page 42, the led stays on continually.
The red led on the esp-01 is lit while connected to my computer and when connected to the circuit.
I have checked the wiring and the code and both are exactly as they are on page 42 of the book.
Thanks in advance,
code download zip and double click on .ino, will load it into Arduino IDE
you can power the esp82-01 using FTDI programmer Vcc and ground only 3.3v
That message means that the code was successfully uploaded to your board.
You can pull the RST to GND (just for a second) to reset the ESP and start running the code.
Please double-check all the wiring and note that the RST pin is left floating (the schematic diagram can be a bit confusing).
