Simple Button Digital Input using Arduino
Digitals
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 …
Time delay for relay using CD4011
Mini Projects
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 …
