4.2 Software Design
The microcontroller
used in our system, is code uses an IoT base platform. The algorithm is
designed in a Arduino Integrate Development Environment (IDE). The upload speed of the setup
is set to 9600 and the setup id connected to COM5, ESP8266 board.

5.1 Experiment Results
The results for the project were gotten from LDRs for the solar tracking system
and the panel that
has a fixed position. The results were recorded for four days, recorded and tabulated. The outputs
of the LDRs were dependent on the light intensity falling on their surfaces. Arduino has a serial
that communicates on digital pins 0 and 1 as well as with the computer through a USB. If these
functions are thus used, pins 0 and 1 can be used for digital input or output.
Arduino environment’s built in serial monitor can be used to communicate with the NodeMcu
board. To collect the results, a code was written that made it possible to collect data from the LDRs
after every one hour.
