Product Introduction ![](media/e1d6d4cc1e21055084c67af12c23386b.jpeg) On the Internet, we often see DIY robotic arm complete various actions. Do you want to have one? I believe that you’ll make your own robotic arm by learning our projects. This kit includes Arduino single-chip microcomputer, 2 joystick modules and 4 servos and so on. Next, we’ll teach you how to install and debug the robotic arm. There are three methods to control it as follows:First, we can a wired home-made joystick controller (included in the kit); secondly, the App control is adapted; thirdly, we also can use a wireless PS2 joystick(not included in kit) . The detailed codes and projects are provided for you. Come and let’s get started with this kit. Note: You must connect a DC 7-15V power to VIN port of shield when wiring servo to shield. # 3. Features - Detailed installation method - Detailed debugging methods, even you’re a beginner - 3 control methods: wired joystick control, Bluetooth control, wireless PS2 joystick control. - Relevant information provided # 4. Specification - Keyestudio servo motor driver shield: - VIN voltage: VIN = DC 7-15V - VIN current: 5A - Size: 73 * 53.34mm - 2-channel 5V Output: 5V / 3A - PS2 interface: Compatible with Sony PS2 receiver, can be plugged directly into the shield. # 5.
