Hi, just check my calculation, I did the following calculations to choose the correct battery for my robot.1-LM324--> if the supply voltage from 7805-----> P1=0.8mA x 5=4mW2-Two Sensor (QRE1113)-----> P2=2x(5x10mA)=100mW3-L298-----> P3=5x60mA=300mA4-Motors(http://www.sparkfun.com/commerce/product_info.php?products_id=319)--->P4=2x(5x230mA)=2300mW5-7414--->P5=1uAx5=5uAso the total power about 2705mW, if the battery voltage is 9.6v , so the current should be 541mA, is this correct???
Note: I do not want to use the calculator of the web.
