Seems fine to me.
Charging the battery would all depend on statring condition of battery and the type of charger and it's maximum current capability.
If you have a 120 A/H battery it means that the battery can supply 120A for one hour, so assuming it's a lead acid battery you can charge it at...
What is your problem? In sending it to screen or generating the data? If you simply need random data you can use rand or srand to generate random numbers and just loop throught your array and populate the array with the randow variables.
Yes, you can not do it like that. You have to use a string related function like a stringcopy or sprintf. Using sprintf like this.
sprintf(month[1],"%s","Jan");
Use a simple voltage divider using two resistors.
|------ 0-12V
< R1
>
|
|------ 0-5V
< R2
>
|------- 0V
Using the e24 series (I think) you can use 1k2 for R1 and 1Kfor R2. You'll have to play around with your math to get values that is closer to real world values...
