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 a various electrical signals to control the operation of the circuit as well. What is Digital? Digital is a kind of electrical signal. Which has work of only two states are: – HIGH or ON or “1” – LOW or OFF or “0” We bring this digital Go to the …
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 of relay that use. Figure 1 Time delay for relay using CD4011 Calculate the discharge time delay Can be calculated by the equation T = R1 x C1 x 0.85 By that: T is the period of the delay is in seconds. R1 is the resistance in ohms. C1 is …
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 easy to use. This circuit is divided into three parts: work special high-voltage level, the scheduling and control electrical appliances. When 220V power supply circuit R1, C1 and ZD1 a special level voltage 220V to rest 10V. The 10V input voltage is power supply to IC1 No. 555. which is …
