Use the X9C104 programmable potentiometer with an Arduino to control the frequency of square waves produced by a 555 timer.
Summary of the project I was needing to run a 6 amp x 12v fan motor over a time during the day for a solar power system in a ship container.
Here I've made a playing time counter for these cartridges.
let's build a circuit to repel the female mosquitoes making noise in your ears and saying "I will bite you soon".
I recently got a Hackster logo badge PCB when attending an event. Here's a short tutorial on how to build it.
Here are 5 different projects using a 555 timer. Great for beginners!
Control servo motor with a 555 timer to understand the servo motor operation
A couple of quick circuits that use the generic 555 IC... plus a horrible little synth :D
Use Meadow.Foundation to quickly and easily wire up a LCD screen and to make a Christmas countdown display.
You can use this Wio terminal timer in the kitchen, bedroom, and gym, etc. （Author：プロフィール）
In this tutorial we will learn how to make a Countdown Timer, you can set time When timer reaches the zero the Relay will trigger the light.
Learn how to turn your micro:bit to a countdown timer that emits light and sound using Snap Circuits components.
Follow these instructions to learn about the different modes of TIMER operation on an STM32 microcontroller using simulation in Proteus
Multifunctional alarm clock for M5Stack Fire
A smart gadget designed to remind elder people about the pill taking time.
The Pomodoro technique is a time management method. The technique uses a timer (work for 25 minutes, rest for 5, and so on).
In this Tutorial, we are going to make "Electronic Digital Clock using Atmel AT89C2051 Controller"
How to create a 4 digit digital clock using the M5Stack Digital-Clock Unit.
Clock alarm temprture senseor and timer, all in one device using an arduino uno and RTC
A timer which registry the activity and inactivity of a PIR sensor, evaluating its potentials.
Explanation on timer module in PIC microcontrollers.
Create a very cheap and effective board for testing a servo using minimal parts. This uses a 555 timer and is sponsored by PCBgogo.com.
It is a small handy 3 bit binary counter that counts up to 10 minutes. Did I mention it's water proof?
Studying the power cycle I needed, switching off NodeMCU was the best solution.
