INA282 Current Sensor
This is my last (!) post about current sensors. The INA282 determines currents by amplifying the voltage dropping across an external shunt. The output value is analog. I show you how to use the INA282 with the Arduino UNO or other microcontrollers.

Wemos D1 Mini Boards
A little breather from current sensors:
I present the Wemos D1 Mini Board with its technical features and show how you integrate it into the Arduino IDE. I will highlight the main differences from the Arduino UNO Board.
ACS712 Current Sensor
The ACS712 current sensor can be used to measure currents in the range of amperes. I show how to get down into the milliampere area and also measure the performance.
