Arduino 2-Step Programmable Timer Circuit
In this article I have explained how to make a simple 2-step Arduino programmable timer circuit, which can be used to switch an electrical load ON/OFF with independently adjustable ON and OFF timings. For example if you want a light to remain ON for 24 hours and OFF for 2 hours, you can simply do […]
Programmable 35238-MP Timer Module? How to Use it
So this 35238-MP Multi-Function Timer module is an digital adjustable programmable timer which we can use it for doing time-based automation things. Inside it, there is a microprocessor that watches time very closely and makes the relay turn ON or OFF after a set time. So this thing is good when we want to turn […]
Programmable Temperature Controller Circuit with Timer
Here I have explained about a circuit configuration which produces adjustable sequential timing outputs for controlling a heater device through a simultaneously sequencing temperature controller circuit which can be also pre-programmed for acquiring the desired temperature levels across the sequencing time slots. The idea was requested by Mr. Carlos Technical Specifications I’m Carlos and I […]
Simple Programmable Timer Circuit
This programmable timer can be used for switching a load ON and OFF with two sets of time delays, which are programmable from 2 seconds to 24 hours independently. The delay timings are adjustable according to the users personal specs. The ON time delay and the OFF time delay are independently settable and this facility […]
Week Day Programmable Timer Circuit
In this post I have explained a couple of interesting timer circuits customized as per individual requirements. The first one is a kind of week/day programmable timer circuit for actuating a motor for a predetermined time only during certain selected days of the week, while the second timer circuit is for alerting a lecturer regarding the finish of the allotted time […]
