These are wired to the motor outputs in parallel to ground through a 4.7k
resistor.

9863 Mon, 7 Feb 2000 19:16:55 +0100 [alt-beam] photovore "henk verbeek" I made i photovore or photopopper and it works oke (i think) (using 2 x
2n3904 2 x 3906 2 x 1381 -j (you know that circuit)). The only thing i want
to know is if its possible in this circuit that both wheels turn at the same
time or is there always only one motor turning. The problem is that the
popper turns right or left following the light , but it isn't going in a
straight line with the two motors turning at the same time.
Maybe i expected to much or is it in the tuning.
Who can help ?
