Our current sensor outputs 5V analog which is too much for the seeduino. We then need to go through a ADC and then through a logic level shifter. This makes us want to maybe use a current sensor that outputs 3V max
CS0350BL would be a good candidate.
On this figure, If is 3A which corresponds to our motor stall current.
It cost around 25€
Additional issue: reading the ADC is slow (~300Hz)
Maye it can be set to continuous mode? What does that mean exactly? see https://github.com/RobTillaart/ADS1X15/blob/master/examples/ADS_continuous_4_channel/ADS_continuous_4_channel.ino
