Getting Started The recommended pathway for the JackBord activities is to complete the guides level by level, in the order of Electronics, Programming, Sensors, Control, then Robotics. For example, you would do all level 1 subjects before moving on to any of the level 2 subjects. However, this is not an enforced rule - feel free to jump ahead if the content is too easy, you want to learn something specific for a project, or are looking for a referenced activity. User Guides Here are the instructional guides explaining how to use your JackBord and its components. View More Student Guides For Learners: These guides will help carry you through the different activities and concepts you learn along the way. Starting from level 1, a complete beginner, to level 8, university level. Teacher Guides For Teachers: These guides will help you teach the content in the classroom. They provide a little bit more information and context which can help you, and your students, understand the how, what, and why. View More Projects These are standalone projects submitted by our team and users. You will find tons of cool projects to work on and impress friends and family! View More Subject Codes Each subject has a code that is 4 digits. The first 2 digits are the subject code, and the fourth digit is the level. For example - 1001 is Electronics level 1, and 1002 is Electronics level 2. For some subjects, the 3rd number is a sub-subject. For example - 2001 is coding level 1, and 2011 is programming level 1.

RC Servos What is an RC Servo? An RC Servo is an electric motor with a gearbox and a shaft. The shaft can be made to rotate at an angle of 0 to 180 degrees. The shaft generally has an attachment, such as an arm, and can be moved at an angle of 0 degrees through to 180 degrees. The position of the shaft is controlled using a pulse width modulation (PWM) signal sent to the servo from the JackBord. As a quick summary, pulse width modulation allows us to control the amount of energy that a power supply (the JackBord) gives to a device (the servo) by essentially turning the power supply on and off really really fast. The diagram to the right shows how the pulse width affects the position of the shaft. Most RC Servos come with three wires: signal, power and ground. These are shown below for the more common models. The ground wire is almost always brown or black, whilst the power supply wire is red and in the centre. The signal wire is usually orange. Notes and Caution RC Servos need 5V power NEVER MANUALLY TURN THE SHAFT as this could destroy the servo Be careful not to overload the servo Connecting to the JackBord To attach the RC Servos to the JackBord, follow the instructions below or one of our videos at the bottom of the page. Place the servo on the JacKano mounting plate, threading the wires through the hole in the middle to the back, as pictured below. Make sure that the long, straight edge of the mounting plate is facing towards you, and the shaft is closest to the left-hand side. When they are lined up correctly, secure the servo to the plate by using the two 8mm M3 bolts and nuts. Line up the holes on the long, straight edge of the mounting plate with the holes at the front of the JackBord, by Port B. Make sure that the shaft is facing up. Secure in place with a bolt in the middle hole. It should look like the one pictured below. On the JackBord, between the POWER Port and Port A, attach the Dual Servo Adapter to the edge using an M4 nut and bolt. As shown in the diagram below, we are going to use jumper wires to connect the RC Servo to the Dual Servo Adapter, and the Dual Servo Adapter to the JackBord. Today we’ll just be connecting Servo 1. Connect the wires from the servo to the dual adapter, lining up the black wire with the green pin, the red wire with the red pin, and the orange wire with the white pin. Then, use jumper wires to connect one of the red pins on the servo adapter to a 5V pin on the POWER Port on the JackBord. Connect a green ground pin from the adapter to a G pin on the POWER Port to ground it. Finally, connect the white pin on the adapter to Port A Pin 1. Once your servo is connected it should look something like this: If you have not done so already, create a profile and adopt the JackBord. Go to the dashboard and open the CMD page. As mentioned earlier, the shaft of the servo can move through an angle between 0 and 180 degrees. To set the servo’s shaft angle we use the svp command: svp [pin] [angle] Where: [pin] is the port pin to which the RC servo is connected to [angle] is the desired shaft angle from 0 to 180 degrees Firstly we need to set the servo’s shaft angle to 0 degrees. In the CMD line, type and enter the following command: svp a1 0 This will move the shaft to the 0 degrees angle. If your servo’s shaft does not move, this simply means that it’s already in that position. When the servo’s shaft has been set to 0 degrees, take one of the small white arms that comes with the kit and attach it to the servo, as shown below. It needs to be pointing to the left, at the 9 o’clock position, and should simply click on. Don’t worry if it’s not exactly aligned, do not forcibly turn it into position. The svp command will set the angle of the servo and leave it there. To have the shaft move between two angles we can use the svs command. The format of the command is: svs [pin] [start] [end] [delay] Where: [pin] is the port pin to which the RC Servo adapter is connected [start] is the desired start angle from 0 to 180 [end] is the desired stop angle from start to 180 [delay] is an optional delay in milliseconds When the servo shaft reaches the end angle, it will automatically return to the start angle. For example, if we wanted to have the servo’s shaft move over the angle of 90 to 125 degrees, we would type in the command line: svs a1 90 125 We can also add a delay to this command so that after each 1 degree step, the servo will wait for the specified delay. Taking the above example, we could add a 100ms delay between steps. For example: svs a1 90 125 100

This program is for the bumper robot. It has a front bumper connected to port A pin A1 and a back bumper connected to port A pin A2. When the robot collides with an object on the front bumper, it will first of all go backwards and secondly it will do a slight turn so as to avoid the object in the future. Likewise when it hits an object in the rear it will move forwards and do a slight turn. < Back Bumper Robot This program is for the bumper robot.

This program will use the sled command in two ways. For this program you need a strip of 4 smart LEDs connected to port pin C5 of the JackBord. This program will set 4 LEDs to colors 1, 2, 3 and 4 respectively and do it live, so the LEDs will update as the program runs. Note there is a 1 second delay between each LED being set. In the second test the LEDs are set to the same colors with the same 1 second delay, except that we added the 0 at the end of each sled command. This tells the JackBord NOT to update the LEDs in real time and instead they all get turned on in one go at the end when the uled command is run. This shows the effect of the uled command. The program will run a few times and stop. < Back Smart Led Example This program will use the sled command in two ways.

This program uses a capacitive soil moisture probe connected to pin a1 of the JackBord to measure the moisture in some soil and display the reading using the USER LED on the JackBord.

The setboot command is used to set one of the programs on the JackBord to run when the JackBord is turned on. < Back Auto Booting/Running a Program The setboot command is used to set one of the programs on the JackBord to run when the JackBord is turned on. Program Setting a Program to Run at Boot The command format is: setboot prog_number Where prog_number is the number of the program we wish to run at boot, ranging from 1 to 10. To set program number 5 to run at boot type: setboot 5 The next time the JackBord starts it will run program number 5. You can check which program is set to auto run using the vp program status command. Once you have set the boot program you can test it using the reboot command to re-start the JackBord, if all is well the selected program should run. Clearing a Set Boot Program Use the setboot command with program number 0 eg: setboot 0 This will stop the currently running boot program and clear it so no program will run automatically on the next boot. Running the Boot Program Just Once To run the boot program just once, ie because it just needs to configure the robot, you should place an exitprog command at the bottom of the prog_loop task. That way the program_loop will only run once and the program will exit. Notes: You cant run other programs while the boot program is running, this is because the JackBord can only run one program at a time. You can use the command line and most of the commands while the boot program is running.
