The proposed push button timer circuit module can be directly integrated with any existing switch contacts of a lamp and enable the lamp to be converted into a timer controlled lamp. A common problem arises whenever one wants to replace a mains AC lamp controlled by a switch with a timer or a time switch. […]
Newly Updated Circuit Projects:
Control Lights, Fan, using TV Remote [Full Circuit Diagram]
In today’s world, the idea of control is strongly connected to the ability to use remote devices. Home automation, known as domotics, allows us to switch ON/OFF various things such as televisions, hi-fi systems, blinds, curtains, garage gates, and even the brightness of lights using a small control unit. The signals for controlling these devices […]
Video Transmitter Circuit
Mini black and white cameras are now available at a low cost. The proposed experimental setup allows wireless transmission of images from a CCD camera module. The entire system is completely autonomous, and numerous applications can be considered: video doorbell, monitoring of a child’s room, onboard video system, aerial photography (modeling), etc. The transmission is […]
Sound Activated Remote Control Circuit
This sound activated remote control circuit can be used to operate any electrical load ON/OFF, through a double sound command. Thus, the circuit ensures that the load cannot be operated through any random single sound triggers, which makes the circuit very fool proof. Our device will require two shifted sound commands. However, the second sound […]
High Voltage DC Motor Speed Regulator Circuit
In the realm of motor control systems, high voltage DC motors play a crucial role in numerous industrial and automotive applications. Efficiently controlling the speed of these motors while ensuring operator safety and isolating sensitive components can be a challenging task. However, with the advent of advanced technologies, such as optocoupler motor controller power stages, […]
