Schematic Arduino Autopilot Control

ArduPilot is a full-featured autopilot based on the Arduino open-source hardware platform. It is a custom PCB with an embedded processor (ATMega168) combined with circuitry to switch between RC control and autopilot control (that's the multiplexer/failsafe, otherwise known as a "MUX"). This controls navigation (following GPS waypoints) and...

Two-Wheeled Balancing Robot Project 3

nBot Balancing RobotThe basic idea for a two-wheeled dynamically balancingrobot is pretty simple: drive the wheels in the directionthat the upper part of the robot is falling. If the wheels canbe driven in such a way as to stay under the robot'scenter of gravity, the robot remains balanced. In practicethis requires two feedback Sensors :...

Schematic AVR Nikon Camera Remote Control

This is an IR remote control for Nikon cameras. The circuit project is very simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery. You can also connect the IR diode directly to the ATtiny13V, but that will limit the LED current and therefore the range. The project is compatible with the Nikon ML-L3 remote control. Supported...
