Underneath most dials and knobs is a device known as a potentiometer. 
Connect the power wire on your servo(s) to 5V and the ground wire to GND. Now, if I turn the dial to its lowest point, it will return a value of 110. The middle pin is a signal that can be attached to an analog pin on the Arduino board to measure how close to the full 5V the signal pin on the potentiometer is outputting. 
val1 = map(val1, 0, 1023, 0, 179); myservo1.attach(6); These are defined before the setup() function (make sure youve created your servo objects and included the Servo.h library here as well). 2) Must use external 5V DC source for servo to avoid extra load on Arduino board. Servo myservo2; Servo myservo2; // create servo object to control a servo, int potpinA0 = 0; // Assign analog pin to potentiometer The potentiometer connections we use in this project are as follows; Two outer pins are power (VCC) and ground (GND) We will use external battery / power when doing this. ser3.attach(4); val1 = analogRead(potpin1); { f@ 30 v*+OVz _w2O^gmg+O_?hqmk3?=~7keC?

The full code includes two sets of the various commands above, with variables assigned for multiple servos, each of which can be operated independently. With that information in mind, the map() function can remap the 0 to 1023 range down to 110 to 150. int potpin4 = 3; At the other end, the full 5V makes it through, and the board reads a value of 1,023. The Servo2 Signal connect to the Arduino Digital PWM 5 Finally, this command will tell the servo to rotate to the position specified after remapping the potentiometer signal.

Cool! Connect 4 servo with Arduino and 4 potentiometer as shown in following connection diagram. int val1 = 0; // Variable to read value from potentiometer, starts at 0, void setup() { While your servos can rotate up to 180 degrees, the pieces theyre attached to may be more limited in their movement.

And so on for each potentiometer you want to add. Keep in mind that each servo will need its own specific range of motion in the map() function.
int val3; This style of potentiometer usually has three pins: two pins on the outside, connected to power and ground. The Servo4 Signal connect to the Arduino Digital PWM 9, The Potentiometers one outer pin connect to the breadboard or the Arduino board VCC input #include Connect the third pin on each potentiometer to 5V The first line here reads the analog pin that the potentiometer is connected to and assigns the value to val0. i'3?B5HQq?o8Q,Za~:q+C5J L==vBi)b|P Mp|kG80d}:G;3?t>wXOV~ ]jznfz)VN'-V@;VG4\NC9Ta4,Y&"&aje Depending on the specific servos you use, there may be some variation so be sure to read the documentation for your materials.
We used the meArm kit for our previous robot guide and well be using the same kit for this one. The Servo3 VCC and GND connect to the breadboards VCC / GND inputs This provides 1,024 levels of resistance that can be measured and, accordingly, 1,024 values that can be passed to your scripts.

Reply 7) Use wires as thin as possible for Potentiometer wiring so potentiometers will reach there extent positions without bearing the tension of thick wires. myservo3.attach(10);
Use 4 potentiometers (variable resistors) to control your robotic arm by varying the position of potentiometer knob. e6)EIgf"{lf||U7$8GzR'F5'_)F]TH_rGetd|lF hV23dp",5g;p~Y7U?K stream The entire code is here if you want to upload it to your Arduino and skip straight to the wiring. However, this is far too high of a range for our servos, which can only rotate up to 180 degrees (and, practically speaking, even less than that as well see in a bit). myservo2.attach(10); // attaches the servo on pin 10 to the servo object int con3 = 2; void loop() ?,-/t|74ysD^lb5gi@q@I{,1yr]/J`uT.n^ShLAI8f-py v3= ?zhJz)=7:'uw70zx,(NRHD>"3lDlB6"x%t+rTX(Cbov2(YG>;H4]a{YllJwoMs)aS(4` \LoNez%v RJ o\ms)3:v(%v*?DMb0w/^yf%P,8mu kN4>*f%^RVz+]@yek9j-{SwSG@OTC~@z{~BC '7N8kn If I rotate it all the way to its highest point, it will return a value of 150. wDsly M6:vM!q(m[U HGyJXecMe @^[AF 05j >-+l&bXH`c_s;/o= feFI6 ?fHm#ORTUw^/_IrJGO"*\2t]Pd2G 2]8@I}r8b%6N1nT3Ls77w$z:a [u^)';Pu+PWdz8B^iMKRive`n.GkvF7^zXQh*b]R.

Save my name, email, and website in this browser for the next time I comment. Put parts together with servos using nuts and bolts: Tinker with the source code with MIT App Inventor or download the apk of the app. <> val2 = analogRead(con3); This guide was written using the TG9z servos on the meArm kit. Servo ser1; /Rttm%fH~ }kw8w - The external battery VCC / GND connect to the breadboard. Servo myservo3; Connect the final pin on the first potentiometer to pin A0 on the Arduino. U wrote very short code for this! void loop() { For this guide, well be using a dial to control multiple servos on a robotic arm. Serial.print(val0); // Print dial/volume position int val; // variable to read the value from the analog pin Our previous guide here goes into more detail on how the servos work, so well focus on the potentiometer here, but well still cover the basics where theyre relevant here.
