Hello,
I am currently working on a project where I need to supply 10-12V to a L298N motor driver (https://wiki.dfrobot.com/MD1.3_2A_Dual_Motor_Controller_SKU_DRI0002) and around 7.5V to an arduino. My goal is to power both the arduino and the l298n from the same source. So I tried to use a voltage divider in to drop the voltage from 12v to 7.5V for the arduino while 12v was connected to the l298n in parallel. However when I powered it, there was only 2V being supplied to the arduino while the l298n got its full load intended. Does anyone know why this is? Is there something fundamental I’m missing? I’m an electronic hobbyist and I’ve a good understanding of circuits and circuit design so I don’t know where I’m going wrong.
Thanks
