Simple Button Digital Input using Arduino
Today we learn the simple simple Button Digital Input using Arduino it is very easy. The Arduino has Digital I/O PINs. Which “I/O” is Input and Output We used the output of Arduino to display the LEDs. Today we need to use the switches as digital input pins to get …
Time delay for relay using CD4011
This time delay relay circuit can be used to time delay for the load, To be connected to the relay output to run after a specified time. Which during this time. Can be adjusted by changing the R1 and / or C1. The current of circuit is limited by type …
Timer control 1-15 minutes by Triac 2N6075 and LM555-LM358
Most timer circuits. Often used with electrical transformers containing low as 9V and 12V, and use of electrical control relays.but the 1-15 minute timer circuit.It uses a triac instead of electrical control.This can be used with a 220V power house it is not connected to the transformer. Make smaller and …
10 minute time delay by fet 2N3819
This circuit is a basic function of the FET 2N3819, which acts as a switch. In the conduction and not conduction. It runs contrary to the transistor. The circuit can be used to delay the cycle is small. Such as delay, 9-volt light bulb, or motor delay to any DC …
Diy surge protector circuits
When has a thunderstorm. Electrical is off, or power surges the extreme, but sometimes we need to use the electrical appliances. And in sensitive electrical appliance damaged easily. Power surges a little. Might make it wastes. In particular surge. At you firstly turn on the switch. Should have the power …
