Custom ESP32-S3 development board — professionally manufactured by JLCPCB. A far cry from where it all started. It Started in a School Science Lab — Around 1998 Most people who get into electronics start with a kit, a tutorial, maybe a breadboard and some LEDs. I started by sneaking ferric chloride out of a school science lab to etch my first PCB. That was around 1998. I was living in the Maldives — a small island nation in the Indian Ocean — where there was no electronics supply chain, no maker community, no local PCB fab. Just a chemistry cabinet at school, a copper-clad board from somewhere, and a lot of curiosity. This post is about what the next 25+ years of PCB prototyping looked like from there. The early wins with proper chemicals, the years of improvisation when those chemicals disappeared, the real injuries, the failed boards, and finally — the moment JLCPCB changed ever...
I tested the communication between PC and Micro controller and finally my tests was perfect. I send an "Hello World" message to PC and from hyper terminal i am able to see the message. Bingo this is another way we can view data other than an LCD.
Later code for the temperature sensor and now the temperature is monitored using PC. So this way we can monitor remotely. I think i should by some wireless modules to interface the micro controller to send data. hope soonnnn..
