    nodemcu and Ai a6 module

    Hi and welcome to our community, To help you out we will need more information about your connections and software used. A clear schematic will help us locate any issue and your code will provide additional insight.
  11. Hi, To achieve what you would like you need a programmable timer to be able to set the ON-OFF time at high precision. I don't know if you can find such timer in the market, as most timers are rated about 16A and are weekly programmable. What possibly you could do is to use a timer to set the ON time and keep the OFF time manually. In this case a timer like: http://www.electronics-lab.com/project/2-digit-99-seconds-timer/ http://www.electronics-lab.com/project/1-to-100-seconds-timer/ may help.

    Practical use of voltage divider

    He will need something more powerful at least for the 16Vdc rail. Something like the LT3845A, which has 60V input voltage and 15A output current may work for this application. Datasheet: https://www.mouser.com/ds/2/609/3845afa-1270855.pdf
