If you want to check your Servo, i think this electronic project is suitable for you. The project use microcontroller AVR AT mega 16 as main processor. The Servo Tester 2 is hardware and software that, basically, makes a pulse width signal between 1 and 2 ms. This is the signal used to control common R/C servos. This one has some advanced features, not usually found on servo testers. This project created by ejbergFeature list:
- Generates two separate signals for driving two servos.
- Sweep mode for stress testing servos.
- Input for reading a servo signal (from a receiver).
- Receiver signal quality analysis.
- Very high resolution at both input and outputs. 0.1µs (which equals 10,000 steps between 1 and 2 ms).
- Voltage and current readout. How much current does your servos actually consume? How much does your receiver pack drop under load?
- Simple user control. Access all features with just a single rotary knob with integrated push button.
- 2 x 16 character LCD.
- Optical tachometer.
- RS-232 connection. Write your own program (PC or whatever), that can control every feature of the tester.
