21. Arduino learning notebook-- Experiment of controlling steering engine Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   Here use Arduino duemilanove to control the rotation of steering engine through a potentiometer. Material preparation: A a rduino duemilanove A 10K potentiometer A steering engine A breadboard Some  connected wires It should be noted here, do not use the computer usb to s upply  power , because if the current demand is greater than 500ma, the  usb  may be burned, it is recommended to use the external power supply. The left and right   pins  of the potentiometer are connected with 3.3V and GND respectively , the middle pin is connected with the analog port 0.   Steering engine  is connected with  5V and GND, the signal port is connected to t...

20.Arduino learning notebook--Use Arduino Duemilanove to download the bootloader to other chips               Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   In this experiment, we use Arduino Duemilanove to download the bootloader to the chip. Note: after testing this method of download ing the bootloader , we found that it only can be tested successfully on   using the 328P of  Arduino Duemilanove, Arduino nano . Material preparation: 1.A c ontrol board of Arduino Duemilanove/UNO/NANO 2.A 100 Ω resistance 3. Two 22p capacitors 4. A 16M Hz rystal Oscillator 5. One Atmega8 DIP packaging chip One key, One breadboard and some connected wires. First, open the arduino IDE, in the File's Examples, select ArduinoISP, compile the program, and download it ...

17. A rduino  learning note book  - stepper motor s   experiment                 Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   Stepp er  motor is an actuator that converts electrical pulse into angular displacement. This is the step per  motor used in this experiment The   stepper motor used in the industry is different from this experiment, the following schematic two different types of industrial step per  motor . Must take a careful  look at the instructions before us ing  stepper motor, confirm  the four phase or two phase, how to connect   each line . T his experiment using the stepper motor is four phase, different color lines are defined as follows: Drive method: (4-1-2 drive) W ire color 1...
