Drone at Code Club

We are putting our coding to the test at Code Club after school. — St Luke's Primary (@DustonStLukes) May 24, 2016

Recently i have been taking a Parrot minedrone and the Tickle App ( to Code Club session, as an extra activity.

For those there actually programmed something that flies and it is quite engaging - having something you are controlling being able to move in all directions.

I wish the mini-drone had a little bit more battery time (I would suggest getting an extra battery). Combining with the drone and the TickleApp does add something to the experience, rather than just control it directly (though that is fun). The noise is also not to everyone's taste so it has to be used carefully in that context, but also from a safety point of view.

First Try with 7bot Robot Arm

In a previous post ( I discussed starting to set up the 7bot robot arm ( . I have still to set up the gripper.

This post document my first tentative steps with playing with it. The code below was used to try and get my head around the positioning of the arm - which servo does what (a good guide for this has been provide by the company online) and what the changing angle on the servos actual does. Essentially the code puts the arm in a starting position and varies the angles from there in usually in 15 or 30 degree increments over seven positions.

#include <Servo.h>
#include <DueFlashStorage.h>
#include <Arm7Bot.h>
Arm7Bot Arm;
void setup() {
  // initial 7Bot Arm

void loop() {
  // set motor[0] speed to 100
  Arm.maxSpeed[0] = 30;
    double angles_0[SERVO_NUM] =  {0, 100, 90,…

Playing with 7bot robot arm

The 7bot is a recent kickstarter project from 7bot. A metal robot arm based around Arduino Due ( Development of the software, at the time of writing, is still ongoing but looks interesting and already on the comments page of the site, user's have started posted their code. 

Had to install the following software and put the un-zipped files in the library folder of the Arduino folder.

Some useful information of setting up using the Arduino Due is available at and is definitely worth a read - it helped me setting it up.

At the moment I have just used the examples from the GitHub site and example is shown in the video below. This looks like an exciting little arm and hopefully there will be more on this blog about it.

I would be interested in …
