Thank you very much. Without you I would be absolutely lost

Well done Tim. Another stunningly helpful video (with high production value),

I'm so glad I found your channel. I'm trying to figure out how to send the temperature from the Pico as a post request to an API endpoint to record it into a database. This video got me a couple of steps closer to that. Thanks!

Wow you make this look so easy. Thank you

Hello Tim, Great video! Now I'm you 645th subscriber 😝, hope to see these kind of great content from you!

Another great video. Thank you!!

Thanks for the video. It was both interesting and useful. I am fine on the software side, but still learning about the hardware. I’m figuring out how to build an automatic door for my chicken shed. I also have a ventilation window that I want to control based on the temperature inside the roosting area. I looked at the Arduino options, but I have a fondness for the Pi family so I thought I’d try the Pi Pico. Not only do I want to control the motors but I’d also like to send status updates via wifi on events. As I need both a motor controller and a wifi capability, I’ve been trying to figure out how to wire up both. So far I think I’m going to need 2 motor controls, 4 inputs for micro switches (2 limit switches per motor), the wifi integration and some sort of temperature sensor integration and a photo sensor input (to open the door in the morning and close in the evening). The whole lot will be powered off a 12v battery and a solar panel. I have a charge controller to manage the panel, battery and load, so I now just have to build up the electronics (load) to do the work.

Neat. if that Serial code had CRC checks, it would have been beyond awesome.

Hi nice video . Leds with mosfit Would put down what you used with your mosfit faret 100 ? And wire diagram as would like make my own Leds stripe work

Very good info. I would like to see how can the PICO push DHT22 data to MYSQL via the ESP01 for a weather station. I am just a hobbyist and I am new to Python and with little knowledge on Arduino IDE. I don't know how to coding in python. It would be great if you could do a video on that. Thanks.

it's nice to see all of this running together, however it is not clear whether it is worth to split the logic of the program between the Pico and the ESP8266, while one could just use AT commands to operate the ESP8266 with its default firmware

I also have "old ESP01" needed to fit 1K resistors between VCC / CH_PD and RST as you suggested......But I also had to change "Builtin Led" in the sketch tools menu from "2" to "1"

Hey Tim, why not a video on sending strings from a mobile phone to the Pico via the ESP-01? Am a beginner, so, I um... need help on that.

man, that is what I was looking for - so if I get it correctly (for my project): 1- build some sensors around Pico (i.e. outdoor temp/hum/press/light sensors) 2- connect it to ESP and put together 3- give them LiPo battery - all will be powered from this battery and left somewhere outside (maybe with some solar charging if needed or not) 4- Pico will collect data from sensors and i.e. every minute will send via ESP to the gathering data server (i.e. Raspberry Pi4 or so at home or even somewhere in the cloud) - then again ESP sleeps, Pico collects further 5- after a minute it all repeats Considering Pico + sensors don't eat too much of power (that is another question to be checked: how much of power Pico with sensors will need) and ESP is only awake for the time of transmission, the entire project should be low power remote sensor. Am I getting this idea right? Thx for video and explanation

When I tried to verify the code for the ESP-01 I got an error: for line 45, "if (http.begin(url)) { // HTTP" when I replaced the line with: "if (http.begin(client, url)) { // HTTP" it worked.

Awesome again, http over wifi on a £1.50 board! I have a json rest server, (nodejs + express) . Whats the best way to read json from the ESP? Is there a packet length max? The response is from my GPS chip and not massive but a few hundred lines of json per read. I assume there is method can send headers and GET/POST the request. Will do this project next week in the bank holiday.

Hi Tim, Please can you advise what packages you installed to get the pi server working, i.e.to get import http.server and import socketserver working. Thanks LKF

I’m getting caught up. 👋🏽

what am i missing?? the title says raspberry pi pico but he’s talking about ESP01

How did you discover your ESP-01 was enhanced and not a regular ESP-01. I’ve noticed my “Regular ESP-01” shows a higher flash available.

Hi, can you explain the "simple server" part and what you mean by "send a message" ? I get the "Ready" text and the "Send msg ...." text but then nothing ?

Is it truly a "Deep Sleep" mode if you are literally shutting down the core? My point is, if it takes a "Reset" to start it up again, then all the previous states were lost, and you have to go through initialization again.

Now the question/problem is... how much consume the Pico in deep sleep ? :-)
