ESP-01 with Firebase RGB Mood Light Real-Time + OTA

Step 1: Setting Up the Firebase

Before we continue we need to setup the Firebase. Go to following link https://firebase.google.com/ and login with your Gmail account.

Once you finish this step we need to make a new project in Firebase, so proceed to your Firebase console.

Under your real-time database there is tab "rules" where you need to enable read and write like this.

You can find your Firebase link and secret here.

This is used in Arduino IDE to connect with Firebase.

Step 2: Program ESP-01 with Basic OTA for Future Update

From source code you can download minimal OTA and flash it with Arduino IDE to your ESP-01.

Now after you flashed it, it should pop up in Arduino IDE port like this.

If it dosent show up here is a link for troubleshooting, or you can ask in comments: http://arduino.esp8266.com/Arduino/versions/2.0.0/doc/ota_updates/ota_updates.html

Step 3: Program ESP-01 with Mood Light Over OTA

Simply download source code from below and flash it via Arduino IDE over OTA like it was previously shown with selecting port of coresponding ESP.

Step 4: Soldering Everything

Simply apply a little solder following the shematic down below.

For power supply I use 5V 1A old phone charger connected to voltage regulator.

Connections:

• Vcc to 3V (Voltage regulator)
• GND to GND
• GPIO0 to Red
• GPIO2 to Green
• GPIO3=RX to Blue
• CH_PD to Vcc (or solder a pull-up resistor on the ESP-01 module)
• optional: push button from GND to RST to reset the module

Since I will enclosure this in my white ball I put some hot glue so it dosent move or break. It works now for a 3 weeks without any problems.

!!IMPORTANT UPDATE!!

I realized one problem with current build and had to put on/off switches on all 3 colors (RGB) between LED and ESP-01 because if you switch it off and then again ON it will stuck in flash mode instead of running the sketch.

Simply turn switches off while you plug it in and then turn switches ON and everyhing will work fine.
