Re: wiring diagram for arduino mega with lots of resistors
Posted: Thu Mar 23, 2017 5:32 amyes some also have a step down from 5v on the arduino to 3.3v, you could try and see how it goes...

1) What are all the resistors doing in this design?
2) This design hooks the 3.3v from the mega directly to the 8266. but I keep reading about making sure the power is regulated and to hook it up to a regulator chip.
3) I'll be receiving and parsing 1 url variable every second from a remote computer and then turning off individual leds representing a 30 second timer. Will the 8266 handle that or do I need to build in a buffer?
Arduino made the design of the board open source, but they still produce the boards themselves. These boards are known as official. Other companies also make Arduino compatible boards.
