Venue: Apartment UniKL BMI
After finished solder the second circuit, i focus through the main circuit. This main circuit is very complicated because have use many component like LEDs, buttons, LCD, and two NodeMCU 8266. The all circuit already finished wiring on breadboard and want to convert the circuit into stripboard.
For the first trial, i use the stripboard got the problem because not really function. I already checked the continuity connection on the stripboard with multimeter that not have problem. But, i dont know why the circuit still not function.
So, the last choice idea, i try not to solder the LCD and LEDs on stripboard and just connect the jumper wire outside from the stripboard. I used the PCB etching technique that for buttons circuit only. Then, for the LCD, i use the arduino jumper and connect to the arduino while the LED and button use the normal jumper wire. Before that, i try to use all the connection wire using the arduino jumper for buttons, LEDs and LCD. The result, button cannot be function. i think the arduino jumper is only compatable with arduino component.
