Right now it seems like the values for x and y are staying at 0 (like HEX, 0,0), even though the servos are rotating. The library knows what type of Arduino you are running on and adjusts the timer16_Sequence_t to match what's available.Hopefully this isn't too basic of a question but I'm having trouble getting the serial to write the degrees of two servos using VarSpeedServo - I'm mapping color values from a sensor into a processing sketch, and need to be able to map their locations by tracking the x and y servo degrees. You have 3 timers but only one is 16 bits Torso.slowmove(pos.toInt(), servoSpeed.toInt()) LeftHand.slowmove(pos.toInt(), servoSpeed.toInt()) // RightHand.slowmove(pos.toInt(), servoSpeed.toInt()) //ĮEPROM.write(rightHandAddr, pos.toInt()) RightForearm.slowmove(pos.toInt(), servoSpeed.toInt()) //ĮEPROM.write(rightForearmAddr, pos.toInt()) RightArm.slowmove(pos.toInt(), servoSpeed.toInt()) // ![]() RightShoulder.write(pos.toInt(), servoSpeed.toInt()) //ĮEPROM.write(rightShoulderAddr, pos.toInt()) LeftForearm.slowmove(pos.toInt(), servoSpeed.toInt()) //ĮEPROM.write(leftForearmAddr, pos.toInt()) LeftArm.slowmove(pos.toInt(), servoSpeed.toInt()) // LeftShoulder.slowmove(pos.toInt(), servoSpeed.toInt()) //ĮEPROM.write(leftShoulderAddr, pos.toInt()) EEPROM.write(eyesLeftRightAddr, pos.toInt()) eyesLeftRight.slowmove(pos.toInt(), servoSpeed.toInt()) HeadUpDown.slowmove(pos.toInt(), servoSpeed.toInt()) //30 - 70ĮEPROM.write(headUpDownAddr, pos.toInt()) You would need to buffer some readings and then write them to the monitor. Serial monitor and/or your eyes will be too slow to follow a normal pwm. HeadLeftRight.slowmove(pos.toInt(), servoSpeed.toInt()) //70 - 150ĮEPROM.write(headLeftRightAddr, pos.toInt()) If you use a 220 ohm resistance wou may prevent damage if you set the pin to output and write an opposite state compared to your output pin. String servoSpeed = parseData(readData,',',2) String device = parseData(readData,',',0) Connect the yellow wire which is control wire to pwm pin 9 of Arduino. HeadLeftRight.slowmove(30, speed) //70 - 150 arduino-servo-control-varspeedservo/ Arduino Code for Arduino Lesson 14. HeadLeftRight.slowmove(70, speed) //70 - 150 HeadLeftRight.slowmove(15, speed) //70 - 150 String parseData(String data, char separator, int index)įor(int i=0 iindex ? data.substring(strIndex, strIndex) : "" RightArm.write(EEPROM.read(rightArmAddr)) RightShoulder.write(EEPROM.read(rightShoulderAddr)) LeftShoulder.write(EEPROM.read(leftShoulderAddr)) LeftForearm.write(EEPROM.read(leftForearmAddr)) rightCalf.write(EEPROM.read(rightCalfAddr)) The analogWrite function provides a simple interface to the hardware PWM, but doesnt provide any control over frequency. leftCalf.write(EEPROM.read(leftCalfAddr)) The Arduinos programming language makes PWM easy to use simply call analogWrite (pin, dut圜ycle), where dut圜ycle is a value from 0 to 255, and pin is one of the PWM pins (3, 5, 6, 9, 10, or 11). rightKnee.write(EEPROM.read(rightKneeAddr)) leftKnee.write(EEPROM.read(leftKneeAddr)) rightHip.write(EEPROM.read(rightHipAddr)) leftHip.write(EEPROM.read(leftHipAddr)) LeftHand.write(EEPROM.read(leftHandAddr)) HeadUpDown.write(EEPROM.read(headUpDownAddr)) HeadLeftRight.write(EEPROM.read(headLeftRightAddr)) eyesLeftRight.write(eyesPositionLeftRight) Int centerHead = 40 // Right = 90 - Left = 0 Int eyesPositionUpDown = 40 //down max = 10 up max 80 Int eyesPositionLeftRight = 40 //right 80 Left = 2 Has any one had this issue before using this library? how would i add another timer? You will see that i have commented out a bunch of servos in order to test out whether or not the number of servos mattered. So i included the Timer.h library found here īut its still not controlling more than 12 servos. However, when I run the following without writing PWM to pin 9, theres no PWM signal on Pin 5. Im am trying to output 10kHz PWM signals on 6 different pins, without interfering with Timer0. From what ive read, the library says to add another timer in order to control more servos. I am using the 0.5 version of this lib on an Mega 1280. I have 20 servos in all that i need to control. The issue im having is that this library only seems to control up to 12 servos on one timer. ![]() I love this library because i can control the speed of the servos. I say robot but its actually a life size T-800 terminator lol. Hello all! Im using the VarSpeedServo library to control servos for my robot.
