Stap 3: Code

Het is een fundamentele twee stepper motor knopbesturingselement. In volgorde blijkt één van de motor pinnen op terwijl de rest zijn uitgeschakeld. Vervolgens gaat de volgende motor pin op terwijl de rest zijn uitgeschakeld, enzovoort. Knop 1 (val 1) is in één richting (motorpin 1,2,3,4) terwijl knop 2 (val 2) is in de andere richting (motorpin 4,3,2,1). De vertraging is hoelang tussen elke stap die de Arduino zal wachten. Hoe kleiner het getal des te sneller. Ik heb ontdekt dat een vertraging van 3 is de snelste de stepper kan gaan.
