Recently i fooled around with some cheap (about 6$) WiFi development boards (ESP82866).
Those modules could be used to easily add more sensors (outside temperature/humidity, light, rain, etc.) that connect back to the PCF via WiFi.
What makes them interesting to me are the following points:
- They can be programmed using standard Arduino IDE.
- Lots of GPIO pins
- Support STA / AP / STA + AP three operating modes
- Micro-USB serial port
- Very cheap => 6$
Blynk to ROS bridge (POC)
The board was connected to my computer running ros-serial via usb (serial connection). The board itself was also connected to my home WiFi for internet access.
Using the Blynk App, I was able to create a custom GUI that allowed me to get and display data from ROS topics. Furthermore, I could send data (values of sliders, buttons, GPS position, magnetometer, etc) to ROS via the GUI.
I was wondering, what you guys think about it
