Ideation
- Pulse Monitoring LED Heart Lamp
- I want to make an Arduino-based LED lamp that monitors heartbeats through a pulse sensor and flashes a heart-shaped LED lampshade at the heartbeat frequency.
Material list
- Arduino Uno: 1
- LED lamp (red or RGB): single LED or RGB LED
- Pulse sensor: 1
- Resistor: resistor of appropriate resistance value
- Connection wire: several
- 3D printing material: PLA translucent 3D printing material
Making process
- Connect the output pin (S) of the pulse sensor to the A0 pin (analog input) of Arduino.
- Connect the VCC and GND of the pulse sensor to the 5V and GND of Arduino respectively.
- If using RGB LED, connect the red, green, and blue pins to digital pins 9, 10, and 11 respectively, and each pin is connected to GND through a resistor.
- Circuit test: Use simple code to test whether the LED and pulse sensor are working properly.
- Make a heart in the modeling software and reserve a wiring hole
- Print a 2mm thick lampshade
- Assemble
