The use of decoupling capacitors on every pair of power supply pins (V DD and V SS) is required. Value and type of capacitor: A 0.1 µF (100 nF), 10-20V capacitor is recommended. The capacitor should be a low-ESR device, with a resonance frequency in the range of 200 MHz and higher. Ceramic capacitors are recommended.
The MCU is powered by 3.3 V. In this particular case, it was a 1000 uF electrolytic capacitor with a 25 V rating (which is a rather large capacitor). However, the odd intermittent resets still occurs now and then, but not nearly as much as it did without the electrolytic capacitor.
The three most common types of capacitors are ceramic, thin film, and electrolytic capacitors, given their versatility, cost-effectiveness, and reliability. This article examines how these three types of capacitors are manufactured and highlights some key differences. What are capacitors made of?

Hope you got the point. If you plan to source small DC motors directly off the MCU board (I had built such boards for my projects), you might want to use larger capacitors (like 4700uF) because motors draw lots of current on startup and would cause huge volatge dip and that would upset all other components (MCU may reset).
The value of the bulk capacitor should be determined based on the trace resistance that connects the power supply source to the device, and the maximum current drawn by the device in the application. In other words, select the bulk capacitor so that it meets the acceptable voltage sag at the device. Typical values range from 4.7 µF to 47 µF.
