Tulipa mecânica sempre florescendo

Sobre este projeto

Como funciona?

• haste de latão de 1 mm
• Tubo de latão de 2 mm com orifício de 1, 2 mm
• fio de cobre de 0,3 mm com isolamento
• Alguma madeira para pedestal
• Arduino Nano
• sensor de toque TTP223
• Pequeno servo

• Como soldar latão (ótimo artigo)
• Como construir com Arduino
• Como usar servos
• Como usar LEDs e NeoPixels

Putting it together (2h)

• servo data wire ⭢ D9 (required for Adafruit_TiCoServo library)
• TTP223 touch sensor data ⭢ D2 (to make use of interrupt)
• Neopixel data ⭢ A0 (any output pin will do)
• Petals ⭢ D3, D4, D5, D6, D10, D11 (any output pins will do)
• Flower ground wire ⭢ GND
• Neopixel VCC wire ⭢ 5V
• TTP223 touch sensor GND ⭢ GND
• TTP223 touch sensor VCC ⭢ 5V
• Servo GND ⭢ GND
• Servo VCC ⭢ 5V
