產品介紹:

如果Arduino Uno微控制器負載過重,你可以求助於專用舵機控制器,它能騰出端口並處理傳感器和其他任務。此外,專用舵機控制器允許設定PWM脈衝頻率和脈衝寬度,為每個舵機指定速度、加速度以及啟動位置,且所有命令都是通過標準的串行連接。你也可以像反射那樣編排若干序列,從Arduino發出單個串行命令以實現觸發。

Pololu生產的Maestro舵機控制器擁有豐富的功能集,形式多樣,可用於自由構架的控製程序。Parallax生產的螺旋槳式控制器是完全可編程的,並且帶有16個舵機的硬件資源和連接端口。這些控制器或其他專用舵機控制器的缺點是成本過高—大約和一個Arduino微控制器的價格一樣。

Parallax也提供了一個介於兩者之間的選擇,它不算是一個控制器,但也可以為Arduino騰出運算資源。Parallax的ServoPAL模組是一個便宜的微型組件,插在舵機引腳和電線之間。它只是簡單地重複從Arduino中接收的前一組PWM脈衝,整個過程無需編程。

The ServoPAL is a tiny module that plugs in between your BASIC Stamp and two servo motors to pulse the motors so your PBASIC program doesn't have to. In addition, it provides an “alarm clock” function to perform timing in the background while the BASIC Stamp is busy with other tasks.

產品規格:

  • Plugs in between servo headers and servos: no wiring necessary
  • Simplifies PBASIC programming for both standard and continuous-rotation servos
  • Pulses two servos continuously based on single pulses received from the BASIC Stamp
  • Provides an alarm output (200mS to 30 min delay), which can be set by a single pulse
  • All interfacing is done by pulsing: no serial protocols to learn
  • Runs from the servo's power (up to 6.5VDC): no additional power source needed
  • Compact size: stackable side-to-side with additional units on 0.1” servo headers
