Detecting Collisions A simple way to detect collisions is to use a switch and the button press command. This allows you to have the robot react in a certain manner when it collides with or makes contact with an object or another robot. ​ Push buttons switches are common but a switch can also simply be two wires making contact as shown below. When the two copper wires make contact with a metallic object, such as another JackBord, the switch is closed and the btp command will take the specified action. ​ The two sections of copper are soldered to some wires which will connect to the JackBord. The white plastic in the middle is an insulator and serves as the mount point for the detector as shown below. ​ The command to use for detecting and counting the collisions is: btp a1 inc /crash1 This assumes the sensor is connected to port pin A1 and that we are using the /crash1 variable to count the collisions.

< Back Car Program with From Obsticle Avoidence This is the basic program for a car with an infrared obsticle detection sensor mounted at the front. The sensor is the Infrared Proximity Obstacle Avoidance Sensor 2cm to 30cm which sends an infrared beam out the front and if this hits something it reflects back and is detected. This alerts the program to the fact there is an obstacle in the way of the Robot. in this case the front_hit task is called. When it detects an obsticle at the front it will stop, go back a little, turn and then move forwards again. It will keep on doing this until it gets out of the obsticles way.

< Back Electronic Dice In this project, you will build on the Rainbow LED project by turning the JackBord into a dice. Using the random function to generate a number and assigning each LED a value (all 5 lit up represents six) makes a very simple electronic dice. Just like the Rainbow LED Display project, we use the same circuit and connect the TOP LEDs to Port A on the JackBord. This time we control the LEDs via a program rather than the command line. This means that we don’t have to manually enter commands every time we want the LEDs to light up, but the program also allows us to give the LEDs a practical function which is, in this case, giving a number between 1 and 6.

Funding Our mission is for JackBord to be the notebook equivalent for STEM subjects in all schools Our early adopter schools have identified the efficiency of the JackBord as being the key item in their teaching toolkit and are setting aside budget to purchase more. We understand some schools may have fully allocated budgets, or simply struggle for sufficient funding to undertake anything other than traditional education, often not enough for many students to achieve curriculum or realise potential; especially those with special needs or where traditional learning fails to trigger their interest. Here are some ideas for schools to consider to fund a system that could make a difference to them and their students. The JackBord Trust Visit Website JackBord Works Limited's main shareholder is a registered charity, the JackBord Trust. ​ The Trust's primary purpose is to find ways to reach and encourage more students to take up coding, engineering and science as careers through educational advancement. ​ The Trust could assist schools and students to find ways to fund its purpose through the purchase and or donation of JackBords from any dividends from its shareholding in the business, or as a vehicle for businesses, parents and other charities to make a tax deductible donation.
