And now, if we go back to WokWi, I can hit F1 and I can load in my firmware and run it on the simulator. So here, Im running in PlatformIO and Im building the blink sketch and compiling it on my computer., So Ill compile the firmware.

This is running a neopixel example., So we import the neopixel and then, when we run it. I can even run bits of Python code here, so we can print hello world.

So if we run this Well see it starts the python, interactive environment and its run and it scan the networks. Not only that you can also do this in Python., So heres the same code but running in Python. The guest network on the WokWi., So you can connect to this and use the internet from your ESP32. So if we run this sketch it will startup and now weve initialized the wi fi and were scanning and its found. , So theres a built in network in the simulation system. There are also more complex, examples., So heres a seven segment display so were using the SevSeg library and then we hit simulate and it updates the seven segment display Theres, also built in support for wi fi, so heres, a sketch that will scan for wi fi networks And it will print out all the details about the wi fi network, its found. Were now running a TinyPICO and running the dot star led. Were going to cycle the colours on the dot star, LED., So heres all the code, and then we just hit simulate. Here we have a TinyPICO board and were pulling in the TinyPICO. It works amazingly well, So thats, a simple blink sketch. And now we can just hit the simulate button and it will start to flash our LED. And then in our loop well set it to high, have a half second delay and then set it to low and then follow that with another half second delay. Now, in the code, we just need to set the pin to output. Well wire this up with the anode connected to a GPIO pin and the cathode connected to ground. Well, do the classic blink sketch., So the first thing well need is an LED. Do you like PCBs? Do you want to make a PCB and a weird and wacky colour like purple, Maybe youd like a flexible, PCB Or maybe youd like someone to do some CNC work for you Check out the link to PCBWay in the description, So lets create an ESP32 sketch.

Theyve got a bunch of examples on their home page, but lets try some esp32 right after this quick word from the channel sponsor PCBWay.
