Unregulated motor ev3 - Below you will find the explanations about how to use Unregulated Motor block control legacy lamp and its advantages over normal . This sequence repeated keeping the lamp turned on first for two seconds and then one. Now the question is can we calculate minimum number of Lamp blocks need to add each sequence iteration loop answer yes just find Common Multiple mcm different timings
It does not work as expected If you run this EV program will see that the turns on lamp but for specified time. Lamp My Block with Port Power and Seconds as input parameters the following example use previous to sequentially control four lamps connected different actuator motor ports of . tagName return while rentNode sj sp pointerdown page true sb feedback. We simply need to set the logic variable True in master program loop just before starting obstacle avoidance and then it back False after at end | unregulated motor ev3 language:en
Seconds but using the same lighting sequence. The following image shows program to accomplish this. The advantage of this last program pattern that you only need to change time each lamp block do not worry about Wait blocks Synchronously turns four lamps for. To finish the exercise try synchronize four different lamps one for each EV actuator port first every. In addition they will learn specific techniques to synchronize different programming flow sequences from duplicating strategically splitting beam or use Master Slave design pattern

One of my main interests is to collaborate with other teachers research how curricular and noncurricular subjects more creatively. We use a logic variable because only have two states or off but could another type if had more than cases. Acquired knowledge With this teaching unit students will learn how to use Motor block control the legacy lamp. So how can we make the code more efficient answer is by creating your own block subprogram called My Tools Builder. Exercise Control the light intensity of legacy lamp using Unregulated Motor block How can we turn progressively its maximum watch effect need use loop increase power each iteration from and then off start again

Can we improve the readability of such program answer lies in splitting sequence beam strategically as shown below that does exactly same previous one. You can use your intuition to complete the number of blocks each sequence. In addition they will learn specific techniques to synchronize different programming flow sequences from duplicating strategically splitting beam or use Master Slave design pattern. As you can see in the above program its readability is much better because icons form graphical pattern that easier to understand

Although this simple exercise we will use it to show some limitations when optimizing the code. Turn the lamp on for one second off then back two seconds What problem with this solution disadvantage that every time you want to need repeat loop. seconds and off every

Addendum To unregulate or not After this post was originally published came across the Unregulated Motor block which happens be much more effective control legacy lamp than . seconds but using the same lighting sequence. In the following example master loop uses logic variable called Lamp to instruct slave turn on or off

The following program uses Unregulated Motor block turn lamp on its maximum power Wait keep for required time another back off using and turned one second. This sequence repeated keeping the lamp turned on first for two seconds and then one. The program is not able to synchronize lamps when using previous My Block since turn and off sequentially instead synchronously

The solution is quite straight forward just create four blocks one each actuator port and program will work fine synchronizing lamps correctly.

The Master Slave design pattern consists of multiple parallel loops executing tasks different rates where one acts controlling others which slaves and communicating with them using messaging architecture. What is the simplest and perhaps most elegant way to do it We can use Modulo operation of Advanced block in such that every iteration loop increases intensity by until reaches

I started the BOGATECH Robotics Workshop to offer activities and support students education centres teachers. To implement a basic Master Slave design pattern in EV we need least two loops the or main program and lamp variable controlled by that tells when fire action condition our case will turn off
