Hello
I have been working on a self project--a car-robot that uses a proximity sensor to stop when faced with a solid obstacle and no more than that--The current that the entire system draws(as ive designed it) is 0.54 Amps. I am currently using a battery used for flying Rc planes. It can provide 9.6V at 1000mAh (as rated). I figured it can do that job with a voltage divider.
1- Ive set up a voltage divider with 10Ω, 10 watt resistor. Well that is because i wasn't to sure of a voltage divider; so i went the other option. The heat generated by this ceramic resistors is insane and i don't like the design of it. I use the output of the voltage divider to power the car-robot
2- The battery when charged by its charger charges up to 11.7 volts. When connected across the voltage divider, the car moves (after an initial push to over come the static friction).
3- When i measured the battery at time full charge, it read 11.62 volts. That is alright since the voltage divider still did the trick. But the battery drains out too soon
4- I only have two questions: 1- Why the does the battery drain so quickly as it says that it can provide up to 1000mAh. I only need 0.54 amps at any given time. 2- If i use the voltage regulator IC LM317, how do i calculate the current through the adjust pin and the output current. I ask this so that i can calculate the power dissipated through the resistors, if i go with the regulator,
Thanks for the time and as always, any reply is a good reply..(as long its relevant..)
