In this experiment, we use Arduino Duemilanove to download the bootloader to the chip.

Note: after testing this method of downloading the bootloader, we found that it only can be tested successfully on using the 328P of Arduino Duemilanove, Arduino nano.

Material preparation:
1.A control 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 into the arduino control board.


  

Connect the hardware first

  





Connect to the usb cable and select the downloaded bootloader from the IDE as Atmega8's NG

  



Then select download bootloader and select arduino as ISP
  


Just look at the flash of the light. After the download, the “Done burning bootloader” will be shown.

If you cannot download, please carefully check the resistance of the connection between the reset port and 5 v, the resistance must be about 110 Ω, 100 Ω is basically no problem.

14.Arduino learning notebook-ITG3200/3205 gyroscope sensor experiment   gyroscope                           Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   I t is a device for sensing and maintaining direction, based on the theory of the immortal angular momentum.   The gyroscope is mainly composed of a wheel which can be rotated around  the axis.   Once the gyroscope starts rotating , the gyroscope has a tendency to resist the direction of change due to  the angular momentum of the wheel.   The gyroscope is used for navigation, positioning and other systems.   In 1850,in order to study the earth's rotation, French physicist J.Foucault discovered the rotor   of the high-speed rotation . B ecause of its inertia l  e...

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...
