Int val // variable to read the value from the analog pin Int potpin = 0 // analog pin used to connect the potentiometer Servo myservo // create servo object to control a servo Controlling a servo position using a potentiometer (variable resistor) You could adapt the below “knob” example for use with the two pots in your joystick to control two servos. You should look at the servo based cam pan/tilt setups that use two servos. i would like a variable speed and i have found a parallax 277800 2-axis joystick that i would like to use to control it through the arduino.
I haven’t picked out any motors yet because i was going to see if there were any suggestions, all i want to do is to be able to attach a laser pointer to a platform that will turn left to right and point up or down. So select the motor for the speed and power you require, then select a compatible H-drive shield or module and power supply and then get down to writing the sketch.
#12 volt forward and reverse motor full#
Well then it sounds like you need a full H-drive module to control the motor rated to be able to handle the voltage and current demands of the motor you do end of selecting. I haven't picked out any motors yet because i was going to see if there were any suggestions, all i want to do is to be able to attach a laser pointer to a platform that will turn left to right and point up or down. What do you wish to use to control the motor, an arduino board running your sketch code, your just How fast can the change of forward/reverse/stop decision be. What is the voltage and maximum current draw for the motor?ĭo you wish to also be able to stop the motor?ĭo you require variable speed control on the motor or just full speed forward or reverse?
