What is a bool Arduino? A boolholds one of two values, true or false. (Each bool variable occupies one byte of memory.) Does Arduino have bool? boolean isa non-standard type alias for bool definedby Arduino. It's recommended to instead use the standard type bool , which is identical....
Another small and cheap LCD option, it behaves in a similar way as USBD480, but with a speed limitation, redrawing the whole screen takes about 0.5s, but simhub is redrawing only changed parts, it allows to get a really nice result as long as the whole screen does not get redrawn at...
There was a great void for a generic robotic software framework. ROS filled that gap and presented a modular, platform-independent approach to robot application development. Because it is free and open-source, anyone can use, modify, debug and contribute to ROS. It can also be used in any ...
ADD and SUBTRACT depending on the condition is CASE STATEMENT ADD COLUMN to variable table? Add prefix in data column Add Time in SQL HH:MM:SS to another HH:MM:SS Adding a column to a large (100 million rows) table with default constraint adding a extra column in a pivot table created...
As Dave is looking for something reminiscent of the 8-bit era (albeit with a more 16-bit memory space), 640x480x12 bit color would only need 450k of memory. In fact, I’d personally go along the route of the Sega Genesis/Megadrive and do 2 sets i.e. foreground and background, ...
Q: How wide is the field of view of a PIR? A: Basic sensors have 100-120° FOV. Lens options like curtains and long range optics provide narrower, longer FOVs. Q: Can PIR sensors see through glass or walls? A: No, obstacles fully or partially block the infrared waves from reaching...
Sub-question 2: How does the development of a game go? The development of a videogame is a long process that could become very expensive. The creation of a videogame goes in different phases., which can also be categorised into different steps. The development goes from an idea, to code...
Pretty much every episode starts out as a single line entry in a note in the Notes app that’s with me all the time. This is where I jot down a rough thought or topic I might like to cover. Sometimes it’s just a word or two, sometimes it’s a paragraph if I have some initial...
expensive for a given display size and they can suffer from screen burn-in when a static image is displayed on a screen for a long time (for instance, the table frame for an airline flight schedule on an indoor sign), not to mention that there is currently no way to re...
The flicker/lines is caused by the PWM frequency of the power supply. I recently made a 12v Arduino controller and I had to change the output PWM from 64 to 32 to avoid the lines. Now I can get pretty short exposures without flicker. ...
