\nBilden visar hur det ser ut n\u00e4r jag kopplat upp kretsen.<\/em><\/p>\n
Nu \u00e4r det dags att starta programmeringsverktyget. I mitt fall Arduino 1.6.11.
\nKoden som ska skrivas in \u00e4r f\u00f6ljande:<\/p>\n
void setup() {<\/em> void loop() {<\/em> Om jag ska beskriva koden kort s\u00e5 \u00e4r det f\u00f6ljande som sker: Koden kommer med andra ord resultera i att LED:en t\u00e4nds och sl\u00e4cks 5 g\u00e5nger per sekund. Med andra ord LED:en blinkar med en frekvens av 5Hz. Nu har det blivit dags att koppla upp den f\u00f6rsta kretsen med hj\u00e4lp av arduino. Det vi vill \u00e5stadkomma i det h\u00e4r inledande skedet \u00e4r att f\u00e5 arduino att blinka en LED. P\u00e5 Arduino-kortet finns p\u00e5 pinne 13 en LED vi skulle kunna anv\u00e4nda f\u00f6r det \u00e4ndam\u00e5let. Men jag kopplar en extern LED p\u00e5 pinne […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-15","post","type-post","status-publish","format-standard","hentry","category-arduino"],"_links":{"self":[{"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/posts\/15","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/comments?post=15"}],"version-history":[{"count":1,"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/posts\/15\/revisions"}],"predecessor-version":[{"id":19,"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/posts\/15\/revisions\/19"}],"wp:attachment":[{"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/media?parent=15"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/categories?post=15"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/arduino.holta.nu\/index.php\/wp-json\/wp\/v2\/tags?post=15"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

\nSetup<\/em>
\n-S\u00e4tt pinne 8 som utg\u00e5ng.

\n-S\u00e4tt pinne 8 h\u00f6g (+5V).
\n-V\u00e4nta 100ms.

\nNu funderar jag p\u00e5 hur jag skulle kunna vidareutveckla kretsen p\u00e5 n\u00e5got s\u00e4tt, kanske genom att f\u00e5 in en yttre signal som talar om hur l\u00e5ng f\u00f6rdr\u00f6jningen ska vara mellan t\u00e4nd och sl\u00e4ckt. Med andra ord, justera hastigheten p\u00e5 blinkningarna. Kanske med hj\u00e4lp av en potentiometer.<\/p>\n","protected":false},"excerpt":{"rendered":"
