LEGO Training ’s SPIKETM Prime is accessible in the marketplace for a couple of yr by now. In our huge take a look at collection, we introduced in to you intimately. The Inventor 51515 which is the SPIKETM ’s house model, will also be purchased by now. The software program of each robots has reached an honest stage. Earlier this yr, we printed our personal e-book for the SPIKETM Prime Software program that may be a useful useful resource for everyone who nonetheless has questions on programming this robotic. For individuals who like paperbacks greater than digital e-books, we additionally promote it as a print-on-demand paperback on amazon.
At brickobotik, we nonetheless proceed to work with the SPIKETM Prime. On the one hand, we use it in our workshops and teacher-trainings. However, we’re additionally within the electro-technics of the SPIKETM Prime. Subsequently, we provide you with somewhat perception in our „briokobotik craft nook“ and current somewhat venture on which we at present work.
An adapter board for the ultrasonic sensor
A lot of you in all probability seen the 2 Torx screws on the again of the ultrasonic sensor within the SPIKETM Prime and the Mindstorms Inventor set which you’ll ‚t discover on the opposite sensors. When you unscrew these two screws, you may take away the white ultrasonic sensor gadget in order that solely the black shell stays in your hand. Right here, the cable of the LEGO Powered Up connector results in a feminine header. This 8-pin feminine header has a pitch of 1.27 mm which can’t be accessed simply with typical Arduino cables. That’s the reason we determined to develop an adapter that breaks out the 1.27 mm pitch to 2.54 mm which is the traditional dimension of the Arduino, perfboards, breadboards and so on.
Technical particulars concerning the breakout board
There are six alerts inside the Energy Features 2.0 connection:
1x 3.3 V energy provide 1x GND
2x digital in-/output (GPIO), which will also be used for UART (115200 Baud, 8N1) Please observe: The GPIOs don’t provide sufficient present to function the LEDs straight! A transistor circuit is critical to provide an LED from the three.3 V rail.
2x PWM for the motors
Please observe: The voltage of those alerts is equipped straight by the SPIKE ’s battery! Aocording to our measurements it’s between 8.4 V and 6.3 V.
Every GPIO sign is supplied with a resistor in collection that gives a minimal safety in opposition to unsuitable GPIO configurations. They will simply be bypassed with a solder bridge.
On the left and proper aspect, the identical alerts are unfold out. On one aspect, you discover the 2 GPIOs along with the ability rails and on the opposite aspect, you discover the PWM alerts with the ability rails. The sign strains to the left and proper don’t solely fan out to contacts of
2.54 mm pitch but in addition to contacts of two.00 mm pitch for the Grove connector system.
The respective 3.3 V energy provide strains are by default open solder bridges. On this approach, two unbiased energy provides won’t compete destructively if for instance a Calliope mini or different microcontroller is used. The open solder bridges may be closed with a little bit of solder if required.
New potentialities with the breakout board
With our breakout board, connecting and utilizing different sensors and motors with the SPIKETM Prime turns into a lot simpler. It additionally opens the potential of connecting the SPIKETM to a microcontroller just like the Calliope mini. However you need to observe one vital constraint: projeots like these are primarily appropriate for superior customers. The wiring in addition to the programming wants expertise with the electronics and the respective sensor protocols.
Technical particulars concerning the management
The Powered Up alerts are straight controllable through the SPIKETM Prime app however solely utilizing Python tasks and on one’s personal account. There isn’t a „UltrasonicBreakout“ Python module or one thing comparable by LEGOO . Nonetheless, descriptions and directions for the respective MicroPython courses and strategies may be discovered within the web. Individuals with expertise with different MicroPython units, particularly with working the MioroPython REPL, can rapidly familiarize with the mandatory particulars.
Order your individual adapter board!
At briokobotik, we’re going to proceed to work with the adapter board and take a look at its conneotion to completely different sensors. However we’d additionally like to offer the potential of experimenting with connections to the SPIKETM Prime to all different house constructors and electro-technios lovers who prefer to attempt it themselves. So, in case you are on this adapter board and want to buy it, simply ship us an electronic mail to [email protected]. We’ll gather all requests and if there are sufficient individuals , we are going to inform you through electronic mail about the potential of preordering the adapter board.
You don ‚t wish to tinker however you have an interest in a sure sensor that could possibly be conneoted to the SPIKETM Prime? Go to our web site at www.briokobotik.de and go away a oomment or a message along with your requests for future tasks and we are going to attempt to take them into consideration.
