Technical requirements
The hardware components that will be needed to develop the solar energy measurement system are as follows:
- One solderless breadboard.
- One Blue Pill microcontroller board.
- One NodeMCU microcontroller.
- One ST-Link/V2 electronic interface for uploading the compiled code to the Blue Pill board. Bear in mind that the ST-Link/V2 requires four female-to-female jumper wires.
- One B25 voltage sensor.
- One solar panel.
- Male-to-male jumper wires.
- Female-to-male jumper wires.
- Power source.
All the components can easily be found at your preferred electronics supplier. Remember, you will require the Arduino IDE and the GitHub repository for this chapter: https://github.com/PacktPublishing/DIY-Microcontroller-Projects-for-Hobbyists/tree/master/Chapter11
