This post lists some ICs commonly used in electronics projects and explains how to buy them for cheap prices at eBay.
The objective of this post is to explain how to control a motor, including its speed, using an ESP8266 and an ULN2803A integrated circuit. Hardware Since the digital pins of a microcontroller can only source a limited amount of current (in the case of the ESP8266, 12 mA maximum [1]), we can't directly use them …
