Brian Lough created a video on YouTube titled “WiFiManager – An Essential ESP32 library!” This video pointed out that hard coded settings on the ESP32 can be a limitation. It went on to demonstrate this with wireless network connectivity and the inherent dependency when preset values are used. The solution rested on a library that gives the ESP32 the ability to operate as a WiFi access point and for the ESP32 to provide a web portal for an attached device….
There is a noticeable difference on how long it takes for a sketch for the ESP-32 to compile when using a Windows based system, versus using a Linux based system. Depending on the sketch, this difference can be up to 10 times, which could frustrate developers. The suggestions online point to anti virus as the cause, with disabling the anti virus or adding exceptions as the workaround. Others recommend using Visual Studio instead of the Arduino IDE. This post will…
This post will cover some use cases of the ESP-32 Cam module in low or no light conditions. The software and hardware of the ESP-32 Cam module will modified for this purpose. Some additional hardware examples will be introduced as well. Lastly, the use of FFMpeg will be demonstrated to further enhance the images gathered from the ESP-32 cam module. What are some reasons for the ESP-32 Cam module to be used in low or no light environments? The more…
The purpose of this post is to demonstrate how to use Processing to present data in a visual way. The methods used in this post will be based on the work done by M.Furkan Bahat. Source – https://mfurkanbahat.blogspot.com/2014/11/artificial-horizon-and-compass-using.html The hardware used in this demonstration will be the following: GY-521 MPU6050 Arduino Uno ESP32-Cam ESP32-USB-Module Patch wiring USB cables Windows 10 laptop The MPU6050 is connected to the Arduino Uno using the following pin connections, as shown in the images below….
