Also note that this is only valid for 5V boards. However, be carrefull that the current you can draw from arduino VIN pin is limited by the protection diode (specified at 1 amp max, for Arduino Uno), so if you use several motors, or put them under a significant load, it is better to connect the power supply separately to the motors. You can use a 9V or 12V power supply to power the arduino and motors.Ĭonnect GND and VIN pins of the arduino to the GND and VCC pins of your dynamixel device, and tx and rx pins of the arduino to the data pin of your dynamixel device (see image here). To control TTL motors, without any additionnal hardware:

InstallationĪrdyno is available in the Arduino Library Manager, or you can get it directly from github repository if you want last version (may be unstable) Usage

) are provided via a very simple high level interface (see test_motor example), but other operations can be done using the generic read/write functions (see test_led example). The most useful functions (speed, position, wheel/joint mode.

You can control TTL models directly from Arduino, without any additional hardware, using hardware or software UART.Ĭommunication speed up to 1 MBd is supported with hardware serial. This library allows you to control the Robotis servo motors that use a custom half-duplex serial protocol. Only Dynamixel 1.0 protocol is supported for now.
