Hi all
need advice on a PCB i am wanting to make based on the lap tracker tk i would like to build this as the commercial ones are way out of my pocket
https://sourceforge.net/p/laptrackertk/wiki/ESP8266%20Part4%20-%20Infra-red/
my knowledge is limited and basic but i am computer engineer and can pick this up quickly , where i fall over is programming language and writing code,
what i would like help with is to modify the arduino code so that when a rc car passes under a barrier that it triggers a buzzer and flash a bank of LED rapid flash 3 times
at a later add on would be nice to have a starting lights sequence
also i need help with the IR bank for light bar - need to wire together in a string of 20 ir led, not sure of the power requirements and the configuration but rate at 12volts max , controlled by a Arduino Nano V3.0, with usb linked to laptop and a com port
using the esp01s with nodemcu and lua scripts but there might be a better way with the code, suggestions welcome looking for a quick way of programming the transponders with a drivers name and a UID, once programmed that transponder can be kept and reused or name wiped and reset
also looking to build a mini router or AP using a esp, for up to 20 es01s transponders to connect to and AP point, port 65000 or the com port,
web access not required at this time i have experiment with 1 of these and got it to work to show up as a wifi
any and all advice welcome
