First off, thank everyone for your continued help
So I did some webcrawling and came across this circuit...im just havin a little trouble picking the correct components.
i 'm changing certain components, however the changes have not been reflected on the diagram... I will list them...
V1=3.0V
V2=1.5V
V3=3.0V
Small DC Motor running off of 600-800mA..
LDR provide 300K ohms in total darkness
LM339 op amp...max Input current of 50mA and max ouput is 20mA..
Self Constructed H-Bridge
NPN 2N2222
1) hfe=200
2) max Ic=800mA Ib=200mA
PNP 2N3906
1) hfe at 10mA > 50
2) max Ic=200mA Ib=100mA
I tried building Boncuks circuit, however, I burned up a transistor, but the motor ran.. and the circuit was just a lil too complicated for my purposes and for me to explain.
To my understanding the transistors are just acting as switches.. being that the motor is receiving its power from V3, and the output of the op amp is small, do I have to worry about my transistors burnin up because of the power demands of my motor?
