Cricket Shot Recognition pogwiritsa ntchito Arduino UNO R4 WiFi + ADXL345 + Edge
Chisonkhezero
Chikalatachi chimapereka mayendedwe athunthu pomanga makina ozindikira kuwombera kwa cricket pogwiritsa ntchito Arduino UNO R4 WiFi yokhala ndi ADXL345 accelerometer ndi Edge Impulse Studio. Ntchitoyi imaphatikizapo kusonkhanitsa deta ya accelerometer, kuphunzitsa chitsanzo cha makina ophunzirira, ndi kutumiza chitsanzo chophunzitsidwa kubwerera ku Arduino kuti chikhale chowombera nthawi yeniyeni.
Masewera a Cricket omwe amaganiziridwa mu polojekitiyi:
- Kuyendetsa galimoto
- Kuyendetsa molunjika
- Kokani Kuwombera
Gawo 1: Zofunikira pa Hardware
- Arduino UNO R4 WiFi
- ADXL345 Accelerometer (I2C)
- Mawaya a Jumper
- Breadboard (ngati mukufuna)
- Chingwe cha USB Type-C
Gawo 2: Zofunikira pa Mapulogalamu
- Arduino IDE (posachedwa)

- laibulale ya Adafruit ADXL345
Khwerero 3: Wiring the ADXL345
Lumikizani sensor ya ADXL345 ku Arduino UNO R4 WiFi motere:
VCC → 3.3V
GND → GND
SDA → SDA (A4)
SCL → SCL (A5)
CS → 3.3V (ngati mukufuna, ya I2C mode)
SDO → yoyandama kapena GND
Khwerero 4: Pangani Sensor ya IDE Yokonzeka
Momwe Mungayikitsire Sensor Library mu Arduino IDE?
Tsegulani Arduino IDE

Kugawa kwa data: 80/20 (sitima / mayeso)
Sungani ndi kuphunzitsa deta
Yang'anani ndikuyang'ana kuyezetsa kwa Model ndi chosungira.
Onani chisokonezo masanjidwewo; ngati bwalo ndi mmwamba zikulumikizana, sonkhanitsani zambiri zosiyanasiyana kapena kusintha
Ma parameter a Spectral (kukula kwazenera / phokoso pansi).
Khwerero 9: Kutumiza ku Arduino
Pitani ku Deployment:
Sankhani laibulale ya Arduino (laibulale ya C ++ imagwiranso ntchito).
Yambitsani EON Compiler (ngati ilipo) kuti muchepetse kukula kwachitsanzo. 
Tsitsani .zip, kenako Arduino IDE: Sketch → Phatikizani Library → Add .ZIP Library… Izi zikuwonjezera exampmonga Static buffer ndi Continuous under File → Eksampizi →
Dzina Lanu Ntchito - Edge Impulse. Chojambula cha Arduino UNO EK R4 WiFi + ADXL345.

Zotulutsa exampLe:
Malangizo:
Sungani EI_CLASSIFIER_INTERVAL_MS mogwirizana ndi ma frequency anu otumizira data (monga 100 Hz → 10 ms). Laibulale ya Edge Impulse imayika izi mosalekeza kuchokera pamalingaliro anu.
Ngati mukufuna kudziwa mosalekeza (zenera lotsetsereka), yambani kuchokera ku Continuous exampndikuphatikizidwa ndi laibulale ya EI ndikusinthana ndi zowerengera za ADXL345.
Tikhala tikuwonjezera maphunziro a kanema posachedwa; mpaka pamenepo, khalani maso - https://www.youtube.com/@RobuInlabs
