Hello all,
May i introduce myself, i am Garrett and am constructing a robot for a class project. I have run into an issue in charging my robot and have not yet been able to locate an answer in this forum and online.
My issue is:
I am going to run two motors with TB6612FNG dual motor controller. To my understanding, i cannot run the power source for these two motors directly off of the EZ-Board... I must supply a seperate power source to the motor connecting it directly to the HBridge and a seperate power source connected to the EZ-Board.
I want to create a docking station that the robot can connect to and charge both the battery for the motors and the EZ-Board without turning the robot off. I cannot seem to find a splitter or the right information to complete this task.
Any ideas?
Thanks,
-Garrett
Okay, i am confused how this relay is going to allow charging and then once the charging is finished it will then somehow allow the batteries to run the robot... Below is another schematic using a relay, does this make any sense how it is hooked up?
need only normal open contact relay charger and battery are hook up together and charge the battery ,then when finished charging the battery battery connect to the circuit you need reed relay rated at 5 volts coil n.o contact and use a npn to turn the relay on from one of the digital outputs on EZB,can do by time or a battery monitor circuit
here is the circuit to drive a relay from digital pin driving a relay from digital output
