relay question #415

Open nickfysiek opened 4 years ago

nickfysiek commented 4 years ago

I am using this code with succes to power my coffee machine but it has 4 relais. I bought one because this is enough and now it's not working. When i use a basic sketch to check the relais, it is working, now it is doing nothing I use a 5v relay and external power. Ground fro the nodemcu and positive from the source.

code i use / Version 0.3 - March 06 2018 /

You have confused pinMode and digitalWrite! You have to use pinMode in setup function (currently there is no pinMode!), and digitalWrite in your on/off function!

nickfysiek commented 4 years ago

sivar thx i did this i put this in setup pinMode(relay, OUTPUT);

and then these

digitalWrite(relay, LOW); digitalWrite(relay, HIGH); and also const int relay = 5;

now it is working, how does it come that the previous code worked with a four module relay?

sivar2311 commented 4 years ago

I don't know your previous code. But i'm sure you will find out.

I don't see the problem in the code, but in my nodeMCU v3 the code is uploaded the serial in the arduino IDE respond with the correct commands the relay on the digital pin2 light up the esp8266 blue led when is on and turn of the esp8266 led when is off, but the relay attached to the pin's don't work and I don't know why.

Can somebody please help

kakopappa commented 4 years ago

Can you turn on/off the relay using a simple sketch?

Hi @kakopappa

This is a good question I'm don't have much experience with the nodeMCU and the esp's stuff, I have some codes for normal arduinos nothing with webserver or webpages, but I google for a simple sketch for do that and yes I can turn on/off the relay using the sketch I found, but I find is:

CODE---MCU

pin0---D3 pin1---TX pin2---D4 pin3---RX

The sketch if found is for ESP01 with 4 relay channel, now I put in my 2 devices the pin 0 and 2, and connect the relay's in the D3 and D4 and work. So the problem is identify the correct pinout of the MCU. Introduction-to-NodeMCU-V3
