Triggering a 5v/125VAC10A relay with a button ?
[note mods: post may in wrong place. please move if necessary.]
hello,
just yesterday put wifi plug socket esp8622 based linknode r4. managed fit 2 125vac wall sockets gangbox(4 separate outlets) along hefty 5v/4a psu, terminal block, switch mains(only kills 125vac, not r4's psu) , standard 3 prong recepticle standard pc power cord power everything.
everything working expected far. linknode app great, albeit slow because of latency between phone - cloud - r4. intend reflash r4 new firmware allow spoof wemo device , therefore allow me control echo dot.
i'd have option of controling each outlet manually , believe can soldering on relay's "on" pin. i'd use small little buttons did our first led project with. had r4 board broken out more of pins wouldn't issue. i'm can accomplish nano. i'd rather however, not waste mcu such simple task.
with of out of way question is: there way control relays needed 5v 1 of little buttons , basic circuitry? ie - can accomplished discreet logic?
tia always

after bit more reading seems ebay pro mini clone or 1 of nanos best choice considering limited amount of realestate i'm working with. did @ 1 point consider pnp/npn transistors still unsure how single button press allow work understand made functional constant current must applied. perhaps i'm incorrect. have little experience transistors.
regardless appears promini trick @ low cost , in small space.
if else has other ideas love hear them haven't yet worked out of potential issues. if have arduino send 5v relay on signal after button press how turn off linknode r4/esp8266? seems cannot hijack 5v "on" pins relay. rather, seems signals esp8266 need somehow rerouted through arduino. it's been long day may not thinking entirely clearly.
again, advice appreciated!
