To save energy, instead of using LDO, switch IC for each circuit block is used after DC/DC converter. Simple MOSFET can play the role as a switch, but load switch IC can include protection circuits, discharge function at off state, and a slew rate control circuit.
As a result, saving space and intensive function realization are possible.
Presented here is a Windows-based project that can control up to eight electrical devices using a personal computer. Connecting a computer to external devices is becoming essential in our day-to-day life for automation.
Presented here is a data acquisition (DAQ) system that can be used to interface six sensors and four digital-to-analogue channels. The acquired voltage levels can be displayed on a personal computer (PC).
Presented here is such a GPS device with a tracking record system. It shows the path traversed by you from the initial position, so you are never lost at unknown locations and can always come back to the initial point.
The solar compass presented here is a navigational tool, which helps in finding directions through the position of sun in the sky as reference. This solar compass is not influenced by magnetism, unlike a regular magnetic compass.
Presented here is a stop clock built with a basic AT89C52 microcontroller that can be used in a variety of fields to measure events. This construction project can also help you understand concepts like real-time use of microcontrollers and scanning related to displays. The device is dual powered and will switch to battery supply if mains is ‘off.’
