    555 circuit to open/close car door window

    Sure! So here is the code: input.buttonD0.onEvent(ButtonEvent.Down, function () { if (!(GoingUp)) { GoingDown = true pins.D1.digitalWrite(true) pause(2000) pins.D1.digitalWrite(false) GoingDown = false } }) input.buttonD0.onEvent(ButtonEvent.Up...

    How to calculate on/off time with 2 Capacitors

    Thank you sir. those look interesting but I do not see any of them with adjustable blink rate.

    555 circuit to open/close car door window

    Good afternoon fellas. I found a solution to the edge detecting to switch between the up and down modes to be MUCH easier with a PIC and was able to do everything with an Adafruit Trinket MO. MUCH cheaper and easier to prototype that building a 555 circuit.

    How to calculate on/off time with 2 Capacitors

    Hello again Delta Prime! So the Diodes are just in there, not sure why they are there but they are not LEDs. The schematic is not my design, I saw it at the video associated worked like I wanted it to, so I copied it but the resistor and capacitor values are off. :( My ultimate goal is to...

    How to calculate on/off time with 2 Capacitors

    Good morning. I hope everyone had a pleasant thanksgiving. I am trying to build a flasher circuit that I can adjust the on and off times. I found the attached circuit and tried it but the times are too long (I am looking for a few seconds, like 0-10 on each vice double or triple digit times)...

    555 circuit to open/close car door window

    Thanks for all the insight and input but the conversations are getting over my mechanical engineering knowledge and comfort level. Sadly, I am trying to understand everything but am getting overwhelmed so I need to take a step back for a while. Thanks for all the assistance and support.

    555 circuit to open/close car door window

    AK - thanks for all the information, definitely getting in over my head. I figured/guessed that my circuit would be 2 smaller 555 circuits, one for each action. But you lost me on the external inverter circuit... The only things I could find on the web about an inverter circuit were about...

    555 circuit to open/close car door window

    Sure, technically it is. However, the impedance of the circuit goes way up once the switch is closed which could cause issues detecting open or closed. I am not sure how to address that with something that is not a PIC. I have an impedance level set in my Arduino code to be above 300 to help...

    555 circuit to open/close car door window

    Much like the power windows, this is totally an add on "feature". You can view the vehicle here

    555 circuit to open/close car door window

    Awesome response, really making me think and remember all at the same time! Yes, the idea is to replace the Arduino with a circuit. I currently am using MOSFETs to drive a 5v relay to complete the circuit to open/close the window. I chose to add relays to the circuit in addition to MOSFETs...

    555 circuit to open/close car door window

    So here is what I have regarding the Arduino but I would like to explore options that do not require a PIC.

    555 circuit to open/close car door window

    Thank you sir. I will have to dig into those options and see what I can do. I have an Arduino Nano (and it is probably a knock-off).

    555 circuit to open/close car door window

    Sir - yes those can be issues but my kids are in the 20s, my dog has hair and it is for my 59 impala. I use this to save the door seals as the glass goes right into the weatherstrip on the top of the opening. The timing is not as important as the function and so far I have not had any issues...

    555 circuit to open/close car door window

    Hello. I have an Arduino board and circuit that I am using to open/close my car door window based on the door being opened or closed but it is a current drain. :( I am hoping someone can assist with a 555 timer circuit that i can use to replace my battery killing PIC. Door opens, switch closes...
