Sou leigo em programação, eu copiei o código no arduino e colei na postagem.

Well if you download the wifiManager library in arduino (as shown on the wifiManager GitHub), you can find examples that would be a good starting point.

Sim,já fiz isto, só que la não ensina como incluir meu código.

If clear instructions didn’t teach you how to properly format your posted code… what more can anyone do?

You need to learn enough basic programming to make proper use of examples… due to the variety of devices, they are rarely plug and play

a formatação que vocês tanto falam é o tradutor da pagina do blynk que está bugada

How about the motion gif in the welcome topic?

Como já disseram sem formatar o seu código é bem difícil de alguém te ajudar.

Qual erro você recebe quando tenta compilar?

@luciano0609 Close… You where just using wrong key. It is the backtick, not the comma or apostrophe.

Blynk - FTFC

I fixed it for you this time :wink:

@luciano0609 esta faltando UM MONTE de codigo do wifi manager, sugiro voce usar esse exemplo e mesclar seu codigo AutoConnectWithFSParameters

Tentei mandar formatado de novo, o exemplo que você me indicou é com MQTT como altero para funcionar com a plataforma do blynk?

Aqui funciona normal, veja se você inclui todas as bibliotecas necessárias.

Como eu disse anteriormente, cheque se você adicionou todas as biblioteca requeridas por esse código que esta tentando usar.

Se você procurar aqui vai encontrar vários exemplos de códigos usando o WiFi Manager, porem eh uma funcao mais avancada.

Se voce apenas quer colocar para ajudar na hora de mudar sua senha do Wifi acho que nao vale a pena visto que voce nao muda sua senha tao frequentemente.

problem comes from the version of ArduinoJson used. (v6 beta)
you can not use this version with wifimanager
you need to install version 5.13
:wink:
