DTMF based FM Remote Control Circuit
In this post I have explained a DTM based FM remote control circuit which can be used for controlling 4 individual appliances remotely by pressing four corresponding buttons on the DTMF transmitter handset. The idea was requested by Mr. Sunaabh Sarkar. Technical Specifications I came across your blog “Homemade The Designs Just for You” quite […]
How to Control Motor with a Cell Phone
In the following post I have explained a very simple circuit idea which can be used for controlling a motor’s rotational direction i.e. for moving it either clockwise or anticlockwise through alternate miss calls from your cell phone. The Circuit Concept I have already discussed a novel cell phone controlled remote switch circuit where the […]
Vibrating Cell Phone Remote Control Circuit
In few of my previous articles I have explained a handful of GSM remote control circuits using ordinary cell phones as the modem. All those designs incorporated the ringtone of the cell phone as the triggering signal. In this post we’ll learn how the same could be achieved but by using the vibrator feature of […]
Control Two Submersible Pumps Alternately
In this post I have explained a simple water level controller circuit applicable for automatic toggling of two submersible water pumps alternately in response to a predetermined water level switching. The entire circuit is built using just a single IC and a few other passive parts. The idea was requested by one of the interested members of […]
