我想做一個單片機控制的小車

ID:200257 · 發表于 2017-5-13 13:18

我對之間電路還不是很了解，比如各個模塊之間的銜接，難一點的我想通過一個wifi模塊來基于socket編程來控制小車，簡單點就搞個巡線算了，有沒有電路原理給我參考參考，謝謝哈

你打算用什么控制器呀 wifi串口現在很多呀

簡單的就是單片機加紅外尋跡模塊加電機驅動模塊再就是小車底盤。這樣就搞定。

可以用藍牙控制啊，相比無線要簡單一點

用WiFi模塊 ESP8266 然后加紅外傳感器單片機電機 PWM模塊差不多可以實現

智能小車基本不需要電路圖，需要電機加上電機驅動模塊，加上單片機控制系統，這樣就可以跑了，需要什么功能就買什么模塊就好，WiFi就買一個WiFi模塊，原理圖必須按照你買的模塊來看原理圖，不同模塊原理圖也不盡相同，程序的話網上好多，這種東西重在自己探索加上請教大神，我剛做一個循跡智能小車也是這么過來的！

pwm在電機驅動模塊上就可以實現吧？還有ESP8266沒用過，不熟悉，只對openwrt還有點了解

我自己設計了了個電路原理圖，不知道可不可行，那個需要電源穩壓模塊嗎，我打算搞4節干電池4.8V

你打算用什么控制器呀 wifi串口現在很多呀

你說wifi模塊的控制處理器嗎，就ESP8266吧，最常見，也便宜
