My Project about Temperature Controlled Circuit

Good day,I have read an article about temperature controlled LEDs. I would like to make one according its circuit diagram.Look at the diagram,it’s nothing but two LEDs (D1 and D2), whose status are controlled by the temperature of the surroundings. The famous IC LM35 is used as the temperature sensor here. Output of LM35 increases by 10mV per degree rise in temperature. Output of LM35 is connected to the non inverting input of the opamp CA3130. The inverting input of the same opamp can be given…See More

Why Pretty Big Electric Shock Existed Here

Hello,thanks for reading my post first.I made a power supply which can produce -12V according to the data-sheet of LM2576-12. The outputted voltage is 24V and the 0.5A re-settable fuse has been used. Occasionally I found a circuit board which exists a situation that the re-settable fuse will protect automatically if overflowing. After that, the lagging circuit has been add in. And the lagging time is about 650ms…See More
