But considering this is a small circuit I can't imagine it'll actually make much of a difference, if the capicitance is the same but a different construction. Hey,

Not sure I can be of much use here, all capacitors work the same, what will be different is it’s effective temperature range and capacitance. But considering this is a small circuit I can’t imagine it’ll actually make much of a difference, if the capicitance is the same but a different construction.

I bought these http://www.ebay.nl/itm/290630163057?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_3283wt_915 AVX - 0.22uF 220nF 50V Y5V 1210 SMD Capacitors - 150pcs from ebay but I think these are the wrong capacitors or am I wrong? Can I use these or not? Please reply, because I might cancel the purchase if these are wrong Hello there, I like your project and decided to make one.

I bought these http://www.ebay.nl/itm/290630163057?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_3283wt_915

AVX – 0.22uF 220nF 50V Y5V 1210 SMD Capacitors – 150pcs

from ebay but I think these are the wrong capacitors or am I wrong?

Can I use these or not?

Please reply, because I might cancel the purchase if these are wrong

So, analogWrite(enablePin,128); // PWM pin number, value (0-255) Yes, applying PWM to the enable pin will vary the output voltage to the motor.

I would check for any common power, for instance if it's on a shared rail etc... and just double check the setup and everything is wired up properly. Odd.

Or is this more a line following robot? so you have 1 IR sensor and you want to drive the motor based upon what it detects? Or is this more a line following robot?
