I like Arduino Pro Mini boards more than other Arduino boards. Mainly because of its minimalist design. But Arduino Pro Mini does not have built in USB interface to program it directly like we do in Arduino Uno. However we can program a Arduino Pro Mini easily using a cheap CP2102 USB to TTL converter […]
Here is the schematic design to create a dual voltage regulator to power our Arduino and other small circuits. It is built around AMS1117 low drop out voltage regulators.
List of standard resistor color codes are given here.
