• For WLtoys A959, A969, A979 RC cars
• Provides about the same functionality as the Traxxas TSM stability management system
• The car tries to follow the direction, which is requested from the steering wheel. Deviations are compensated with countersteering
• I also have an Adruino RC system with fully integrated MRSC: https://github.com/TheDIYGuy999/Micro_RC_Receiver
• Version for 3 pin standard RC servos: https://github.com/TheDIYGuy999/MRSC_Adapter_3Pin_Servo
• Programmable with Arduino IDE
• Input for feedback potentiometer of a WLtoys 5 pin servo
• The simulated potentimeter feedback is sent to the WLtoys receiver / ESC
• Uses a standard Sparkfun "Pro Micro" 8MHz, 3.3V or an 8MHz, 3.3V Pro Mini
• MPU-6050 gyro / accelerometer wired to the I2C pins
• Gain potentiometer
• Input for gyro direction inversion (if the MPU-6050 is mounted upside down)

New in V 0.1

• Initial commit
• Not yet tested in a car

New in V 0.2

• Built a compact sandwich with MPU-6050 and Pro Micro Board, including a low pass filter for the analog output
• Software cleaned up and optimized. Gyro calibration removed. Board is now immedialtely ready after power on.
• First indoor test in a WLtoys A979-B done
• Both the pot and the direction switches are disabled. So the standard values Gain 20% & Inversed = true are active. You can activate them in the main loop, if required.
