Since you probably don't use most of the buttons on your remote control, why not make them work for other things? This project shows you how to use an Arduino to decode the signal from a remote and ...

This circuit is low cost and can be constructed easily. By using this circuit, we can control any house hold appliance with the help of remote. This circuit is low cost and can be constructed easily.

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transistors ...

A very interesting remote controlled alarm circuit using TSOP1736. Routing of an electric cable to attach a calling bell switch near the bed of an old age/patient is not a good idea. Here is an ultra ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

Every now and then a remote control acts up. Maybe you are trying to change the channel on your television and it’s just not working. A quick way to determine if the remote control is still working is ...
