AVR-T32U4 Arduino Leonardo Analog Servo motor drive demo

Image

We stock now 6 types of Analog Servo drive motors https://www.olimex.com/Products/RobotParts/ServoMotors/

The motor parameters are encoded in their names:

MS-1.3-9 means – Servo-Motor with 1.3 kg.cm force and 9 gram weight.
MS-R-1.3-9 means Servo-Motor with 360 degree angle and 1.3 kg.cm force and 9 gram weight.

All servo motors came with various exchangable plastic arms:

Separately are available aluminum ARMs which can snap to the bigger 3.2 kg.cm and 6 kg.cm motors, these are so powerful than can open and close drawers.

Adruino have special library for servo drive just notice that the normal servos will accept angle between 0 and 120 degree only, while the R type will accept from 0 to 360 degree.

The demo code is on GitHub: https://github.com/OLIMEX/DUINO/tree/master/AVR/SERVO

You can see the code running on this video http://www.youtube.com/watch?v=OdH7dr4Aa30

Friday Free Board Quiz issue #25 is RPI-UEXT + MOD-IO2

Image

RPI-UEXT allow Raspberry Pi to have access to different modules see original blog post we made about it: https://olimex.wordpress.com/2012/11/21/raspberry-pi-gpio-to-breadboard-and-uext-adapter/

MOD-IO2 allow RaspberryPi to control 2 relays and to read/write 7 additional GPIOs, including Analog inputs. On top of this MOD-IO2 is stackable and addressable so you can stack and connect to Raspberry Pi as many relays as you need for your project.

You have chance to win RPI-UEXT + CABLE26-pin + MOD-IO2 today if you answer correctly our quiz question!

Today at 17.00 o’clock our local Bulgarian time (GMT+2) we will post on Twitter our questions.

You have one hour to reply to our tweet with the correct answer.

At 18.00 o’clock we will count the correct answers and ask random.org to generate random number in range then announce the winner and ship the board by airmail in Monday.

Good Luck!
