CORRECTION AND CHANGES TO SCHEMATIC.

It took a while for me to notice a "little" error in the previously posted schematic. I missed a pull up resistor for the buttons and misspelled some net names . Fortunately, I noticed it before starting the layout of the PCB. In my bid to correct the mistake, I thought it wise to review the components used with the device and made the following changes.

PCB LAYOUT.

I began laying out the components on the board with the aim of making the  PCB as small as possible. There was a limit to its size as I used 0805 components for easy hand soldering ( I can't cope with smaller components ,YET ). I used the ESP32 Pico D4 chip for smaller size. The PCB measured 5 cm by 3.6 cm at the end.

The new schematic and layout has been uploaded in the project page. Off to JLCPCB...
