How to communicate over 433mhz radio?
Hello. I’m trying to get my ESP8266 to send signals via 433mhz transmitter that another device can receive and translate. How do I do this? Thanks in advance for your help.

Machine learning on ESP-32?
Hello! I have the ESP-EYE, which comes with a camera and some face recognition algorithms on the chip. Unfortunately, all the software is written in C. I'd like to: a. Create new firmware for it in Micropython b. Have that firmware access the onboard camera c. Detect faces and particularly whether o...

Re: [workaround found] ESP8266 - use of Timer without storing reference leads to Fatal exception 28(LoadProhibitedCause)
Hello. I'm trying to make it so when a sensor on my board is triggered, a red LED flashes in a pattern. And when a different sensor is triggered, a yellow LED flashes in a different pattern. I'm having a hard time making them both go at the same time, and loop until the sensor is no longer triggered...

Re: ntptime.py howto change host
Ok yes, you can change the host. In the code you mentioned, the url is just set to the variable name "host". So you can change that. Also, for the number next to it in socket.getaddrinfo(host, 123), the "123" is just a random number, using but the program will use that as the port number for connect...

Re: Lolin board erase everything from flash
The board is so tiny, it wouldn't surprise me if it had no such function. A good idea might be to hook it up to a cell phone charger battery. I bought one for my Rpi and it keeps the thing powered for 3 days on one charge. It would be best if the cell phone charger battery has both an in port and an...

Re: Interrupt Handling problem
This looks like a job for debouncing :) The problem when you press a button is, in the fraction of a second it takes for you to press it down and let it go, the board can perform thousands of operations, so it gets kinda confused when it receives and input so slowly. You can solve that by forcing it...

Can I connect to a new network without using a serial connection?
Hello. I'm designing a product with an embedded ESP8266. Customers would need to connect this ESP8266 to their wifi network, which is likely password-protected. I'm wondering if there is any way for them to get their network name and password into the ESP8266 without having to physically plug into i...
