2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Nov yog qhov koj qhov txiaj ntsig kawg yuav tsum yog tom qab muab tso ua ke thiab tso cov cai.

Kauj Ruam 1: Yam Koj Yuav Tsum Tau

Jumper Wires, 220 OHM resistor, 16x2 LCD Screen, Push Button, Servo Motor, Breadboard, Arduino Uno.

Kauj ruam 2: Code
