Solder a cable that connects the 5V pin to the ability column (middle pin of the header) and a small cable that connects the facility of the opposite column (Figure 6-17). Repeat a similar technique with the floor (one cable shape Arduino floor to the floor column, and a small cable connecting the 2 columns flooring among them). determine 6-17. Strip board, energy, and flooring Now, attach all of the signs to the corresponding pin. you want to solder one cable connecting the Arduino pin strip to the header sign. it is crucial that you just do that in a tidy and orderly demeanour (see Figures 6-18 and 6-19) so it’s effortless that you can consider which pin quantity connects to every servo. 111 CHAPTER 6 KINECT NETWORKED PUPPET determine 6-18. Strip board, all pins attached entrance determine 6-19. Strip board, all pins attached again then you definately can plug on your Arduino (Figure 6-20) and do a primary attempt. 112 CHAPTER 6 KINECT NETWORKED PUPPET determine 6-20. Strip board, hooked up for attempt trying out the Servos The code for this primary try out is kind of just like the single within the servo advent, yet rather than utilizing a potentiometer you will preserve the servo relocating from zero to one hundred eighty levels and again to 0. this fashion you could fee if all the servos paintings correctly or in case you have to debug the circuit (making convinced that the soldering is true! ). The code calls all of the servo pins as outputs and updates each one pin with a pulse that might switch among values 500-2500 (0-180 degrees). as soon as it arrives at 2500, it's going to lessen to 500. int int int int int int int int int servo3Pin = three; servo4Pin = four; servo5Pin = five; servo6Pin = 6; servo7Pin = 7; servo8Pin = eight; servo9Pin = nine; servo10Pin = 10; servo11Pin = eleven; int servoPulse = 1500; int speedServo = 50; unsigned lengthy previousMillis = zero; lengthy period = 20; void setup() { pinMode (servo3Pin, pinMode (servo4Pin, pinMode (servo5Pin, pinMode (servo6Pin, OUTPUT); OUTPUT); OUTPUT); OUTPUT); 113 CHAPTER 6 KINECT NETWORKED PUPPET pinMode pinMode pinMode pinMode pinMode (servo7Pin, OUTPUT); (servo8Pin, OUTPUT); (servo9Pin, OUTPUT); (servo10Pin, OUTPUT); (servo11Pin, OUTPUT); } void loop() { unsigned lengthy currentMillis = millis(); if(currentMillis - previousMillis > period) { previousMillis = currentMillis; updateServo(servo3Pin, servoPulse); updateServo(servo4Pin, servoPulse); updateServo(servo5Pin, servoPulse); updateServo(servo6Pin, servoPulse); updateServo(servo7Pin, servoPulse); updateServo(servo8Pin, servoPulse); updateServo(servo9Pin, servoPulse); updateServo(servo10Pin, servoPulse); updateServo(servo11Pin, servoPulse); servoPulse += speedServo; if(servoPulse > 2500 || servoPulse <500){ speedServo *= -1; } } } void updateServo (int pin, int pulse){ digitalWrite(pin, HIGH); delayMicroseconds(pulse); digitalWrite(pin, LOW); } when you add the code, all servos should still begin to movement. If one servo doesn’t movement, payment the circuit, the connections, and the Arduino pin (in case the fault is within the code). evidently, the Arduino 5V energy isn’t adequate for working all 9 servos whilst.
