A filter is a useful tool for removing unwanted signals from a sensor measurement. There is complicated math behind how they work, but you just need to know a simple formula to use them in many embedded designs.
Sensing the Source Current in an Embedded Application
This is a simple, low-cost way to measure the current output at the power source of an embedded system using a microcontroller’s ADC input.
ADC Thermistor Circuit and Lookup Table
Thermistors are simple to integrate in embedded designs but their temperature response can be challenging to interpret. A lookup table is a convenient way to convert a thermistor’s ADC reading to temperature.
