I noticed most pins have a voltage of about 0.01V which is simply not enough to drive any wings. In Mbed OS i start all my programs by MAX32630FTHR pegasus(MAX32630FTHR::VIO_3V3); to set all the pins ...

Observed a 0.4v difference between the actual analog voltage and the voltage read with Internal Analog Reference 1.1v, when an external analog reference voltage is connected to the AREF pin of Arduino ...

If you use the analog inputs of your favorite microcontrollers, sooner or later you have needed to check their linearity and accuracy over the entire range of input values. This precise and compact ...

The ATMega328 microcontroller as mounted on the Arduino UNO board has a 10-bit AD converter. Let’s use its function analogRead to measure some voltages with. How can we improve the accuracy of the ...

If you’ve used the analogRead () function then you’ve already measured a voltage using the Arduino. But do you know what is going on behind the scenes to make this happen?

So in this tutorial build an easy and cheap DIY Pedometer using Arduino and accelerometer. This Pedometer will count the number of footsteps and display them on a 16x2 LCD module.

Microchip PAC1921 monitors PSU voltage and current via a single pin Yes, now that Microchip has introduced its PAC1921, which does just that. The trick is that it also has a serial bus that tells the ...
