This code accompanies the blog post at

This drop controller manages:

  • creating up to two liquid drops that will create a splash
  • triggering a camera using its IR interface to capture the splash image.

Basic hardware modules/components required are:

  • Arduino Uno or other similar controller
  • Solenoid controller valve (see below)
  • 12V power for the Solenoid valve (eg, a LiPO battery pack)
  • MOSFET or simple Transistor to switch the solenoid
  • Rotary Encoder with built-in switch
  • Infrared Transmitter LED for trigger signal to the camera
  • 4-line by 20 character (2004) LCD mode with I2C interface
  • Tact switch
