Circuitry🔌

Parts Needed...

• NodeMCU CP2102
• Arduino Nano R3
• SSD1306 OLED Display
• Capacitive Touch Sensor
• Piezo Buzzers
• DS3231 RTC Module
• WS2812 RGB LED Strip
• Power Supply (5V 10A AC to DC)
• 180Ω - 220Ω Resistors
• 100uf Capaciticator
• Red and Green LED
• Switches (For Break Connections when Uploading a Sketch)
• Wires and Breadboards to Make Connections

To Calculate The Amp of the Power Supply

Every LED consists of 3 Red, Green, Blue lights.

That Single LED Uses 20mA.

So a LED With Full Brightness with White Color uses 60mA.


Minimum Amps Needed at full Power Usage = NUM_OF_LEDS * 60
