AMS1117 1A LDO Voltage Adjustable Regulator Circuits
It is a low-drop regulator, which means that it reaches its maximum efficiency with an input voltage that only needs to be a little bit higher than the output voltage, or around 0.9V to 1.2V. Read more
Solar Powered Automatic Plant Watering System
This circuit consists mainly of the following components: a solar cell, a DC pump, a 555 timer, and an LM311 comparator. It worked well and was also very efficient, requiring only power from the solar cell rather than a battery. Read more
