Dear community!
Please help me as I am stuck in theimplementation phase of my project. I am constructing a moving car, which is moved by means of two dc motors (12 V, 500 rpm). Motors are controlled by a 16F877A PIC. Even though microprocessor and the motor driver IC L298 are fed from different sources the microprocessor resets whenever sufficiently high current is drawn by the motors.
J20 is on off switch (may be considered permamently closed)
J18 is a 9V battery
J19 is a reset switch (may be considered permemently open)
J17 is 8x1.5 batteries
U2s are voltage regulators (down to 5 volts)
capacitor C1 is in real life two capacitors connected in parallel: electrolytic 470 uF and non-electrolytic 0.1uF
R33, R34, R35, R36 are 470 ohms, though i tried 10 kohms as well but nothing changed
Please help! What can be the reason of such an odd behavor??
