Electronic Project : Servo Tester 2

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 ejberg

Feature 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.
