Demonstration of NEMA 17 stepper motor being activated on/off by changing the light intensity on the LDR light dependent resistor. The Arduino switches the motor on when the light falls.<br /><br />The Arduino is powered from the L298 stepper driver 5v supply, which is connected to the mains via a 12v adaptor. <br /><br />ARDUINO MEGA 2560 REV3 : <a href="https://amzn.to/2MM0k3E" target="_blank" rel="nofollow">https://amzn.to/2MM0k3E</a><br />NEMA 17 Stepper Motor : <a href="https://amzn.to/2nMDtN1" target="_blank" rel="nofollow">https://amzn.to/2nMDtN1</a><br />Filmora : <a href="https://amzn.to/2VIBvKh" target="_blank" rel="nofollow">https://amzn.to/2VIBvKh</a> (That's what this video was made with)<br /><br />#LDR #NEMA17 #STEPPER #Arduino<br /><br />Check out the Minimalist online python IDE :<br /><a href="https://epyco.herokuapp.com/" target="_blank" rel="nofollow">https://epyco.herokuapp.com/</a> <br /><a href="https://epico.herokuapp.com/" target="_blank" rel="nofollow">https://epico.herokuapp.com/</a><br /><br />Buy Dr Pi a Coffee...or Tea! : <a href="https://www.buymeacoffee.com/DrPi" target="_blank" rel="nofollow">https://www.buymeacoffee.com/DrPi</a><br />...<br /><a href="https://www.youtube.com/watch?v=NSWmaZS3JtA" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=NSWmaZS3JtA</a>
