led - Need help controlling a relay using a dimming …

2017/10/23· Hi all, I am trying to control a relay with the dome light of my car, however the light has a dimming function that I cannot easily remove (built into the Body Control Module of the car). The light turns off shortly after all doors are closed or the car is locked and turns on when the car is unlocked.

arduino - LED''s connected to a relay remain on? - …

2014/12/19· But the LED''s will not turn off as I dial the pot. back down toward 0. The relays indie that they are being turned off on the module (they each have a LED indior), but the LED''s I connected remain on no matter what. The standard 5V output from the Arduino board is powering the relay module, LED''s, and the sensor.

Problem in using 4 Relay Module to light LED - Arduino

2016/7/3· The led is fried because there was no resistor in series. He needs to remove the resistor and rotate it 90 degrees counter clockwise, move it over so one end connect to the led and then move the wire to the other lead, and replace the led.

Arduino + Relay | coeleveld

The relay module allows you to use a separate power supply to drive the relay coils. Optocouplers are in use to isolate the Arduino output pins from the circuit driving the relay coils. An optocoupler consists of a LED that shines light on a light-sensitive transistor. The transistor will conduct if the LED is lit.

1. Remove the module cover. 2. Check the LEDs. When the pump is switched on and the module is correctly mounted, the left LED must be flashing and the right LED must be permanently on. 3. Refit the module cover. Permanently on Flashing Input for start

Relay Timer with LED Display – Arduino++

2016/2/27· For each digit, the LED segments representing the current time, or message, are illuminated for a very short time. A circuit is created by setting the digit selection I/O HIGH (or LOW, depending on whether common anode or hode) and the corresponding segments to the opposite setting if they are on – the voltage difference then allows current to flow between the common and the segments.
