esp8266

development tools:

           Arduino IDE, Android Studio, Tianwen Block

Voice module:

         Version 3 and below use the module of Tianwen 51, which can be found by directly searching for voice recognition on a certain treasure, the official website address ( Tianwen Block (haohaodada.com) )

   To program the chip, you need to download their software. After installation, open the NodeMcu driver oledDIY.hd source code in the attachment. Graphical programming is used to lower the development threshold.

Version 4 and subsequent versions use the SU-03T module from the movement smart store. Don’t ask why you choose this, it’s cheap! ! !

WIFI module: using ESP8266-12F, you can take it home for 6 yuan!

Speaker: I bought it from Mubao. I have to say that this speaker is really hard to find. It is mainly SMD type, and the power is not the common 8Ω 0.5W, but 8Ω 1W. You can find it by searching for the smart fingerprint lock speaker keyword. , No free shipping! This... is a bad review! But things are pretty cheap

Actual photo shoot:

The previous versions have more or less problems. Since there are too many version updates, I won’t mention them one by one.

When each version is updated, the reason for the update and the shortcomings of the previous version will be explained. The current version 4 test has not been successful, which is outrageous. If anyone finds the problem, you can tell me, I will be grateful!

Each version supports APP control, the effects are as follows:

I have put all the source code in the attachment. My comments are very clear (personal feeling). If you have any questions, please leave a message in the comment area.
