2) Hardware Setup
- Arduino Mega 1280/2560 compatible or Teensy++2
- 2 servos ( If you use a 180° for the pan axis, you will need a 180° one for the tilt axis to cover 360°. If you use a 360° servo for pan, then a 90° servo is sufficient for tilt. )
- 3 push buttons
- A serial wireless link with your UAV. Anything that can bring back some telemetry data to the ground Can be Xbee, 3DR modules, Openlrsng, Oplinks, Audio FSK modems
- a 5V voltage regulator capable of drawing enough amps for your servos + electronics.
- an I2C 4x20 LCD screen.
Cheapest & best one is from HobbyKing:
Supported: I2C TWI Serial 2004 , LCD03, LCD05, Arduino-IIC-LCD, GY-LCD-V1
Optional:
- an HMC5883L i2c compass.
- a MinimOSD board loaded with GhettOSD
- Piezzo buzzer 5V.
- a voltage divider for mesuring lipo voltage(you can use frsky voltage sensor if you're too lazy to make one)
Warning: DO NOT power your servo nor minimOSD from your Mega or Teensy board. Use external 5V/Gnd from the ubec directly. You should do the same for the LCD too.
