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 ...

19.Arduino learning n otebook-- Atmega8 makes the minimum  arduino system                        Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   Atmega8 is the cheapest of the arduino's officially supported chips, so we'll take it to explain how to make the arduino minimum system on the breadboard. Prepare the material 1. One Atmega8 DIP packaging chip 2 .   One 16MHz Crystal Oscillator 3 . Two 22P capaci tors One key, One breadboard and some connected wires. Let's look at this chip A new chip needs to download the arduino's bootloader, which We use the official recommended USBtinyISP to download. Take a look at the pins of Atmega8 and ICSP pins + 5 v connects to VCC GND connect s  to GND D11, D12, D13 connec...

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...
