can we use esp8266 in place of arduino

[@letmindcreative]

Yes but, other processes or programing required to make this

Youcan increase the number of relays by changing max loop value to your desired value and adding pins to the *RelayPins[i[={}* section

mera arduino kam nahi kar raha he

[@letmindcreative]

How can I help you sir ??

[@aiyolo2914]

can hc05 rxt pin connect to 5v?

[@letmindcreative]

No bro rx pin of hc05 is connected to tx of arduino and tx pin connect to rx of arduino and connect the hc05 to 5v which is provided in arduino board

[@aiyolo2914]

@@letmindcreativebut the tx pin of arduino is 5v also, so directly connecting may be unsafe?

[@letmindcreative]

@@aiyolo2914 no bro use arduino 5v pin to provide 5v to hc05 module and connect rx to to tx and tx to rx of arduino module simple
