Powering pump (with timer) from solar - Arduino Forum I have ordered the following components for my project: 10W Panel 12V UPS Battery A bunch of nanos A 12v pump The aim of the project is to use these items as well as some mosfets, capacitors, light sensor, leds and maybe a small display (to show voltage out of solar and out of battery) to turn the pump on and off on a timer (that may change depending on temp once I add a temperature probe
Using a 555 timer to drive a piezo buzzer - Arduino Forum Hi, I'm trying to hook up a piezo buzzer (the one from the arduino starter kit) with a 555 timer I'm using the following instructions : Build a Simple Laser Tripwire Alarm | Make: The issue is that I'm only hearing a single "click" coming from the piezo when the light beam is interrupted instead of an actual sound The piezo works (I've hooked it up to an Arduino to play a melody) and the 555
Pausing and resume timer with millis () - Arduino Forum Hello, I am a bit shame because I have this issue that I want to solve I'm basically measuring current time with millis() to use it as a stopwatch But I want to find a way to see how can I measure time and be able to pause the timer that was running with it's progress and resume it There's any body that has an example or something similar to this use case?
How to create a 38 Khz pulse with arduino using timer or PWM? Take a look at the timer section in the data sheet, and also have a look here AVR Timers – CTC Mode | maxEmbedded for more information on having a timer toggle a pin in the background purely through hardware Just make sure you don't tread on anything else that is using a particular timer, or there might be issues
