Hi,I want to measure a resistance of about 0.4-1.6 ohms with an Arduino. I'm guessing this can't be done by a simple voltage divider because of the low resistances.How could I achieve this? The measurement doesn't have to be very accurate. The question i
When powering the Micro from the DC power connector, use a power supply or battery with an output of 6.5 to 18 VDC. That will ensure a solid 4.95 to 5.05 VDC output of the regulator, meeting any current requirement of the Micro. The onboard regulator will permit operation below the expec...
The ground connected resistor, as well as the feedback resistor, are matched. These are the gain determining resistors. By having a high input impedance, it minimises the effects of loading on the circuit i.e. preventing high amounts of current from driving through the device which can have ...

If you cannot upload the code, you may have to set the board as an Arduino Uno using the tools menu. If the display doesn't turn on, check its I2C address with whomever you bought it from. By default in the code it is 0x3C. You can change it by setting the DISPLAY_ADDR variable...
The Arduino Nano does not include any built-in pull-up resistors nor a 3.3V power pin. The accelerometer must be attached to the toolhead. One needs to design a proper mount that fits their own 3D printer. It is better to align the axes of the accelerometer with the printer's...
