Arduino Ultrasonic Car 超聲波車

"Learn by Play " is the idea of BachCode.

I did learn a lot by assembling this Arduino toy car.

“從遊戲中學習” 是BachCode的想法。

通過組裝這個Arduino的玩具車，我學到了很多。

Let me introduce: 

L298N motor driver board,  Motors

讓我介紹一下： 

L298N電機驅動板 , 電機

Connect L298N motor driver boar with  the two motors and battery compartment.

連接L298N電機驅動板，兩個電機，電池盒。

Ultrasonic module 超聲波模塊
ARDUINO 328 controller  ARDUINO 328給力板

L298N motor driver board L298N電機驅動板

Steering gear  舵機 

Connect and Test with program - Unfortunately, I got only a extremely unclear manual, and a program with error!! What a trial-and-error learning process. :)

連接和測試程序 - 不幸的是，我只有一個非常不清楚的說明書，和一個錯誤的程序！！真是一個 "嘗試和錯誤學習" 的過程！:)

My note. 我的手記

Establish the PTZ (Pan-Tilt-Zoom) and install Steering gear.

復原編輯建立雲台和安裝的舵機。

Mount all component onto the rack. ....and New problem discovered !!  

安裝所有組件到機架。....和.....發現新的問題！ ：|

The PTZ is damaged. I should not put it too front.

Could you see the strange angle of ultrasonic module at the front?

Lesson I learnt: Engineering design is not talking only about concept and programming. Testing in the real situation is very important.

雲台損壞了。我不應該把它放太前面。

你可看到超聲波模塊的奇怪角度。 :(

我學到的教訓：工程設計不單止是概念和編程。測試在實際情況中是非常重要的。

Some more close-ups, if you are not yet bored.

再來一些特寫，如果你還沒有厭倦。

Please email me if you need a clear manual, and a correct programming. :P
如果你需要一個明確的使用說明書，一個正確的編程，請發郵件給我。 :P

Weekend: Arduino Car 週末預告: Arduino 智能小車

One of the reasons that I enjoy writing this blog is that it provides me excuse to buy new toys and electronics frequently.

I have just ordered an Arduino car and some other accessories (in order to save postal charge). Looking forwards to its arrival tomorrow. Happy Arduinoing this weekend!

我喜歡寫這篇博客的原因之一是，它提供了我藉口買新玩具和電子產品。

我剛剛購買了一個Arduino小車和其他一些配件(以節省郵政)。預計明天到達。週末 Arduinoing快樂！

Noise from Motor 電機的噪音

Noice from motor affects the voice sensor. Kids suggest to wrap the motor with plastic sheets, for reducinng the noice. Not a bad idea !
電機的噪音太大了罷，干擾了聲音感應器，小朋友動動腦肋用膠紙包著電機以減低聲浪，效果不俗。

Voice-Activated Car 聲控小車

We have kids to plan for and build a voice-actived car. Car moves forwards and backwards while kids shout. The wind turbine direction also changes accordingly.

這星期的工作坊和小朋友一起計劃及建造這聲控小車。小朋友叫一聲，小車向前；小朋友再叫一聲，小車向後。小風車的轉向也隨之而轉變。

"Brain" of a Robot 機械人的"大腦"

"Brain" of a robot = CPU + Harddisk + RAM
that controls the power supplies, sensors (ie. input), and motors (ie. output), of a robot,
with proper control from programs (ie. logic).

機械人的"大腦" = 中央處理器 + 硬盤 + 記憶體
以控制機械人的 能量來源，感應器 (即: 輸入)，及電機 (即: 輸出)，
並配以切適的程序  (即: 邏緝)。
