Claw machine, also known as object selection and selling, is commonly known as doll clamping machine in Taiwan, China, and doll clamping machine in Hong Kong, China. It is also called claw grabbing machine in China. This type of machine may not be able to catch the desired items, or it may be clamped after being clamped. You may even get nothing for a single shock, but with good luck or skill, you may be able to obtain goods for a small amount of money. Therefore, compared with the function of selling items, its function is more as a game or gambling that provides fun.
Nowadays, every claw machine will be embedded with a sound effect chip, which triggers the sound effect by pressing a button. After the consumer controls the arm to reach the desired position and clicks the button, the robot arm will fall and there will be a special sound effect;
sound effect Chip solution recommended. WT58F02B-8S
Shenzhen Weichuang Zhiyin has developed a low-cost, low-power, reprogrammable voice chip: WT588F02B-8S; this is a 16-bit DSP voice chip with an internal oscillation of 32Mhz and a 16-bit PWM Decoding; a single chip can store 170 seconds of voice capacity at higher sound quality, and can accommodate 320 seconds of audio content if there is no requirement for sound quality; built-in 8R0.5W power amplifier circuit, which can be connected to an external DAC power amplifier;
WT588F02B-8S is different from The biggest breakthrough of the traditional one-time programming voice chip is that customers can change the internal voice content of the chip online through the supporting downloader; and the chip has built-in hardware SPI, UART, IIC, comparator and other various resources, which can Customize a variety of different personalized functional products for customers.
WT588F02B-8S Functional Features
1. 16-bit DSP voice chip, 32Mhz internal oscillation;
2. Working voltage 2.0~5.5V (reset voltage before V1.35 is 2.2V, after V1.35 it is 2.0V);
3. 16bit PWM/DAC output can directly drive 8R 0.5W speakers;
4. Supports WAV files of 6K~32Khz;
5. Customers can replace the internal voice content of the chip through MCU or supporting downloader;
6. Supports one-line serial port and two-line serial port (UART and IIC communication will be released one after another);
7. Supports up to 6 channels of midi playback;
8. Supports more than 1000 addresses;
9. It has hardware SPI interface, UART interface, IIC, built-in comparator and other interfaces. Various functions can be customized for customers.
10． The chip has built-in 220KB Flash.
11． Both the chip main control program and Flash data can be erased and reprogrammed.
12． The chip power-on initialization time is approximately 200ms
13. After the chip plays, and the IO port (DATA and CLK) maintains a stable level (both high and low levels are acceptable) for 1S, the chip enters sleep
