Quick tutorial: current sensing for DC motors
— June 15th, 2012
On her blog, Dustyn Roberts presents her own experience on current sensing for controlling DC electric motors with an Arduino board and an Arduino Motor Shield. This shield, based on a L298 H-bridge, provides two current sensing pins to the user, which can be used to measure the instantaneous current absorpion by each H-bridge. After some trials, Dustyn managed to have a quite clear picture of the absorption behavior of the DC motor:
