Building a Drone on a Budget: Part 1

Introduction

• Objective: Build a budget-friendly drone using ARR boards.
• Focus: Create a custom six-channel transmitter and receiver.
• Comparison: DIY setup vs. commercial Fly Sky system.
• Upcoming Video: Assembly of the drone using the created setup.

Components and Setup

• Components Needed:
  • Zero PCB
  • Two joystick modules
• Functions of Joystick Modules:
  • Control throttle and yaw
  • Handle roll and pitch
• Assembly Process:
  • Place components on Zero PCB.
  • Follow provided connection diagram for assembly.

Soldering and Professional Tips

• Soldering:
  • Complete connections to ensure clean front and back.
  • Back may look messy with wires but can be managed.

Learning Resources and Tools

• Sponsor: LDM 365 and LDM Student Lab
  • Offers free access to PCB design software (LDM Designer) and collaboration tools (LDM 365).
  • Provides structured university-level courses and certifications.
  • Use of advanced tools like power analyzers.
• PCB Design and Ordering:
  • Design PCB using LDM Designer.
  • Order from nextpcb.com for professional quality.

Programming the Transmitter

• Requirements:
  • Use NRF24 library.
  • Arduino Nano board.
  • Upload code for operation verification.
• Outcome:
  • OLED display works perfectly.
  • Transmitter part is ready.

Building the Receiver

• Components Needed:
  • Another Arduino Nano
  • NRF24 module
  • 3.3V adapter
  • Additional resistors
• Connection:
  • Use adapter board to regulate voltage (NRF24 modules use 3.3V).
  • Connect according to the circuit diagram.

Programming and Troubleshooting the Receiver

• Programming:
  • Add fail-safe mode for gradual throttle reduction.
  • Upload code for operational readiness.
• Troubleshooting:
  • Add 100uF capacitor to reduce noise and improve stability.
  • Disconnect OLED to resolve processing delays.

Final Adjustments and 3D Printing

• Outcome:
  • System is responsive and ready for action.
• 3D Printing:
  • Made a 3D printed case for the transmitter.
  • 3D files available on their website.
