option 1.

Traffic light controller


This would be a very simple device to create and would allow me to change the output this can include timing or order of sequnece based on the code within the Arduino software.

Parts required:

  • Arduino UNO
  • 1KΩ Resistor X 12
  • Red LEDs X 4
  • Yellow LEDs X 4
  • Green LEDs X 4
  • Connecting wires
  • Prototyping board
  • Power adapter

Option 2.

Arduino-Powered Temperature Controller


This is a powered temperature controller it is used to keep a certain temperature and maintane a consistent result. It is normally constructed when growing plants or keeping wildlife that relies heavily on temperature.

Parts required:

  • Temperature sensor
  • Relay or RC plug switches
  • Screw terminals
  • Box to trap the heat
  • Heating/cooling element


Option 3.

Arduino-Powered laser turret


The laser turret is created purely for fu but can be used for practical reasons if required. If equipped with a sensor it an be used as a warning device for anything that may cross it.

Parts required:

  • 2 servos
  • Laser module
  • Piezo buzzer
  • Metal wire and cable ties


Option 4.

Arduino-Powered robot arm


The robotic arm can be used to grab objects and move the to another location, this can only be used on small objects.

Parts required:

  • 6 servo´s
  • lexan 2mm
  • distance sensor
  • 10mm led (optional.
  • stative
  • claw
