[Technology] ESP32 Smart Money Bank Education Edition self-study kit set can expand functions by itself

📙Buyers who need unified editing just need to leave a message in the order notes📙 🙏Things to know before buying🙏 In this self-study kit for smart money deposit boxes, we will provide the basic program as seen in the video. You can use this program as a basis to develop a more cool smart money deposit box. For example, you can use the built-in WiFi module to connect to the Internet. , display NTP time, weather information, stock information, etc., and can also use built-in Bluetooth to achieve human-computer interaction, etc. 🔔Warm reminder🔔 This is not a self-study kit for ESP32 beginners. Please evaluate it carefully before deciding whether to buy it. It is recommended that people who have used Arduino IDE will be more suitable. You can use it directly after receiving the product. You can also ask for sample programs in private messages. The program is built-in With detailed explanations, you can research and add the functions you want by yourself. [Mainboard Specifications] MCU: ESP32-S WiFi module: built-in (can expand functions by yourself) Bluetooth module: built-in (can expand functions by yourself) Power supply interface: USB TYPE C (can be powered by mobile phone charging head and mobile power supply) Physical buttons: Built-in a key to reset the total amount of the piggy bank to zero (other functions can be expanded by yourself) Program code: Free copy of the original program code written in Arduino IDE (use NODE32S when compiling) Program library: Use SSD1306 OLED library (provided with the program) 【Product Description】 In the past, coin acceptor modules were all ready-made, but often due to their large size, rigid shape, and limited functions, the functions and appearance of the finished projects were not good-looking. Now, we spent a year and finally made our own The coin acceptor module is not only functionally stable, and the wooden shape is warm and not rigid, but more importantly, it breaks the existing functions. Not only can it automatically identify the type of coins, automatically add them up and use them as a money box, it can also write its own WiFi code. and Bluetooth code to expand functions, such as being able to connect to the Internet, display NTP time, weather information, stock information, or even make a money box that can transmit lines, etc. You can also use the built-in Bluetooth to do things like functions such as computer interaction and external message communication. [Default identification of coin types] NT$1, NT$5, NT$10 and NT$50 【Identification Technology】 Using the combination of infrared sensing and mathematical formulas, we will guide you to learn basic mathematical formulas for calculating the diameter of coins, and use the calculation results to identify the size and type of coins, overcoming the traditional detection of coin size only, resulting in frequent detection. The problem of uncertainty 【OLED screen】 When inserting coins, the recognized coin type will be displayed on the OLED screen in a small animation, and the current total amount will be added up. The actual action is as described in the video [Money drawer function] It can automatically identify coin types and add them up, creating a cool smart money box. [The function of saving the total amount of the money box in case of power failure] It is inevitable to encounter power outages or power outages. If there is no power outage save function, the total amount previously deposited will disappear. In order to prevent this problem, we will save the deposited amount every time we successfully identify the coins and add up the total amount. The total amount of the money box is written into the memory dedicated for power-off storage. When the power is restored, the total amount of the money box will be read back. This completes the power-off saving function of the total amount of the money box. [Reset the total amount of the piggy bank to zero button] When the piggy bank is full and you take out the coins, press the white button (zero button) on the panel to reset the total amount to zero and start another money saving activity. 【Additional features】 Not only can it be used as a desk accessory, it also serves as a pen holder and miscellaneous storage. This makes the smart money box a multi-functional device that integrates into your life and provides a neat and organized space on your desktop. [You can write your own code to expand the following functions] 1. Connect to the Internet to create a smart money box that transmits lines 2. Connect to the Internet to display the current time, weather information and even stock prices, etc. 3. Use Bluetooth function to realize human-computer interaction 4. The program can be rewritten to become a coin counting machine, making counting coins super easy. 5. The coin diameter range can be rewritten to identify coins from other countries. [What the seller says] In summary, this self-study smart money box will lead you through practical operations and programming code learning to gain an in-depth understanding of how to combine infrared sensing, mathematical formulas, programming and other technologies to create a feature-rich and practical smart money box. Whether you are interested in hardware production or software programming, you can find satisfaction and growth in this self-study smart money box. This is an excellent opportunity to explore the combination of technology and handicrafts, and create your own wisdom together. Piggy bank.
