最近開發的
MotoPiduino持續改良修正問題,目前MotoPiduino搭配Raspberry Pi測試已告一段落,預計下個月應該可以上市! MotoPiduino主要是搭起Raspberry Pi跟Arduino之間的橋樑,可以把Arduino的擴充板直接插在MotoPiduino上作運用,除此,MotoPiduino還有內建馬達驅動IC,可以直接驅動兩顆DC直流馬達. 此影片範例即是利用Android手機遙控Raspberry Pi來控制馬達運轉! 在Part 2中將接上Raspberry Pi專用的攝影模組,可以即時傳輸影像(這是Arduino所辦不到), 敬請期待!!
使用材料:
1. Raspberry Pi
2.
MotoPiduino
3. 5V 行動電源
4. 9V 電池 (驅動馬達)
5. USB WiFi Dongle
6. 圓形車體
遙控車程式(Python):
