i recently bought a Servomotor and i'm hopping to use it as motor , i read that it have 3 wires red (+5v) , black (gnd) and command wire
well , i created a small program using pic 16f84 allow me to generate pwm signal (Period = 20ms , pulse = 1ms) , but all i have is a 90° Rotation :shock: and it stops
Whats the problem and how can i use it as motor
@bigdogguru : Thank you for making this claire to me, i think i should just a DC motor
the servo i have is HSR-1425CR and i read in this article that its already modified to work as motor
**broken link removed**
am i lucky or i have to buy Motors ?
and what does this means :
Control System: +Pulse Width Control 1500usec Neutral
Required Pulse: 4.8-6.0 Volt Peak to Peak Square Wave
i mean whats the value if the period and the pulse
If it is a Continuous Rotation (CR) Servo, then you are lucky!
I have actually never used a CR Servo.
However, I believe it means the servo is held stationary with a duty cycle of 1.5ms and total cycle of 20ms.
If the duty cycle (pulse width) is less than 1.5ms the servo rotates counter clockwise, if it is greater than 1.5ms it rotates clockwise and the farther the duty cycle (pulse width) from neutral the faster the rotation.
Did you notice the servo with the tire attached?
