Remote Control Circuits

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 […]

The proposed TV remote jammer circuit can be used for freezing and scrambling all TV remotes under the  specified vicinity.  How TV Remote Works As we all know the fundamental technology used in today’s TV or similar remote controls is Infrared (IR) light. The IR spectrum of light is invisible to the human eye, but […]

In this article I have explained how to make a simple RF remote control circuit using ready-made RF 433MHz and 315MHZ RF modules, and without incorporating microcontroler ICs. With the easy availability of RF modules today making an RF remote control has become a childs play. It’s all about procuring the RF modules ready made […]

In this article I have explained a simple infrared (IR) remote control circuit which is configured for operating a DC motor in response to the switching made from a standard IR remote handset such as a TV remote or a DVD remote. The connected motor can be moved either ways and also can be made to halt. […]

The following post illustrates a simple light toggled/operated remote control circuit, which can be activated by an ordinary flashlight or more effectively through  a laser beam unit (key chain type). The circuit idea may be understood with the below mentioned points: How the Circuit Functions Transistor T3 along with the associated parts and the LDR […]
