LED and Lamps
Temperature Controlled LED Circuit
This small Temperature Controlled LED Circuit can feel the heat! When place near warm thing, it sense temperature and LED glow. It work very simple using one diode and one transistor only. No microcontroller, no sensor IC, just few parts. We can build it easy at home and see how heat make light turn ON. […]
LDR Based Dark Sensor Circuit
This small LDR Based Dark Sensor Circuit is very smart. It can see light and dark using LDR. When there is light, everything stay quiet. When it becomes dark then LED start to glow and buzzer makes sound. No need to touch anything it works by itself. It is easy to make with low cost […]
