Advanced Arduino Project Ideas

• Monome
• Synthesizer
• Motion Tracking Turret
• Autopilot with GPS waypointing
• Gameconsole
• Learning Maze Solver Robot
• Energy efficiency/reporting: put current sensors on each circuit breaker in the AC panel and report usage/stats.
• Whole house climate control: Control HVAC and ceiling fans, watch for diffs between upstairs/downstairs, ceiling/floor and outside temps.
• UPS/power control system: Add power control and usage reporting to a normal UPS (Uninterruptible Power Supply)
• Voice recognition library
• Use Arduino to collect and process position/weather/telemetry data and then output data strings serially into an amateur radio transmitter using APRS (Automatic Packet Reporting System).
• Ham radio repeater controller with DTMF control.
• Arduino communication: Create robots with IR blasters and receivers that can "talk" to each other and tell one's "voice" from another'.
