I purchased the Arduino UNO R3 development board for 23 yuan. Since it is relatively expensive, the board type and chip are consistent with the official version priced at 88 yuan, using ATmega16U2 or ATmega8U2 for USB to serial conversion.

Specifications:

■ Operating Voltage: 5V

■ Input Voltage: No external power supply needed when connected via USB or external 7V~12V DC input

■ Microprocessor: ATmega328P, erase/write life of 10,000 times, priced around 7 yuan

■ Clock Frequency: 16 MHz

■ 14 digital I/O pins, maximum current of 40mA, be careful not to exceed this current during experiments

■ 6 analog input A0 to A5: 10-bit resolution, default input signal range is 0 to 5V

■ AREF: Reference voltage for analog input signals

■ Flash Memory: 32 KB (0.5 KB used for bootloader in ATmega328P)

■ LED: Reserved interface for testing LED (pin 13), lights up when output is high

If you feel that this development board is too expensive, you can also buy cheaper compatible boards, priced from 13 to 19 yuan, and they work the same, with the only difference being the USB to serial chip. The cheaper boards use CH340G, which may require an additional driver installation, download link:

First Time Using Arduino UNO R3

Download

Download the integrated development environment ARDUINO 1.6.12 from the official website

https://www.arduino.cc/en/Main/Software

Installation

Double-click arduino-1.6.12-windows.exe, follow the installation guide, and confirm through the defaults. After installation, the Arduino software logo will appear on your desktop for the next use.

Configure Development Environment

Insert the Arduino UNO R3 development board, and the system will automatically install the USB driver.

Select the corresponding board

Select Port

You can check the port corresponding to the device through the device manager; this machine corresponds to COM5.

Verify

Open the file, examples, and find the Blink program

Click the checkmark to verify if the program can compile successfully; if everything is normal, click the right arrow to upload the compiled program to the Arduino UNO R3’s AVR microcontroller; you can also click that arrow directly, and the IDE will first perform verification and then upload if successful.

If you see the LED light blinking, everything is normal. Congratulations, you have officially started your university journey. Next, you can purchase development boards, jumper wires, and various components for various interesting experiments. The colorful shaking stick uses ws2812 LED beads, which you can search for on Taobao.

With the arrival of the global analog electronics season, the revival of circuit design is quietly happening. I’ve heard that in the future, even advertisements will be replaced with transistors and field-effect transistors, just thinking about it is exciting!
