Cold Gas Thruster Attitude Controller Kit with Arduino Mega + MPU6050
Build a Real-Time Cold Gas Thruster Attitude Controller with Arduino Mega and MPU6050
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Fire virtual cold gas thrusters in pairs to stabilize a mock spacecraft just like a real rocket’s attitude control system. This kit combines an Arduino Mega 2560, MPU6050 gyroscope/accelerometer, and six relay-driven thruster channels to demonstrate pitch, yaw, and roll corrections in real time. Watch live telemetry on the 0.96-inch OLED while you master the control loops that guide rockets from launch to orbit.
What You'll Build
A fully functional testbed that reads orientation from the MPU6050 IMU and activates thruster pairs to counter unwanted rotation. The OLED displays current angular rates and individual thruster status, mimicking the flight computer of a cold‑gas reaction control system. You’ll gain a tactile understanding of how real spacecraft maintain precise pointing under disturbance.
What You'll Learn
- Implement a PID control algorithm for attitude stabilization using only gyroscope feedback
- Interface the MPU6050 over I2C and perform sensor fusion to derive clean angular velocity
- Drive six relay outputs in differential pairs to simulate pitch, yaw, and roll thruster firing
- Display real‑time angular data and relay states on a 0.96-inch OLED using the U8g2 graphics library
- Solder a custom prototype board with diodes and capacitors for noise‑immune, flight‑like wiring

Who This Kit Is For
Designed for second‑ and third‑year B.Tech ECE/EEE students, Smart India Hackathon participants, and rocketry club members at IITs, NITs, VIT, or BITS. It’s ideal for CANSAT or student‑rocket projects that require a demonstration of closed‑loop attitude control, as well as ATL Tinkering Lab mentors guiding advanced learners through real‑time embedded systems.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to open the AI companion trained on this kit; for quick questions, WhatsApp us directly. The companion walks you through wiring, code upload, and tuning the PID gains step by step.
Do I need actual solenoid valves or compressed air?
No. The kit uses relay modules and LEDs to simulate thruster action safely. You can connect external 12V solenoid valves to the relay outputs if you have a compressed air supply and want a physical demonstration.
Can I integrate this controller with a model rocket or drone?
Yes. The relay signals are simply on/off logic; you can replace them with electronic speed controllers or real cold gas valves to actuate fins or thrusters. The code structure remains the same.
What prior knowledge is needed?
You should be comfortable with Arduino C++ and basic sensor interfacing. We guide you through the control theory, but familiarity with PID concepts and breadboarding will help you get to a working prototype faster.
Solenoid valves simulate cold gas thrusters firing in pairs for pitch, yaw and roll control from MPU6050.
