digital electronics projects

Ever want a no-frills reminder for weekly tasks without all the fuss or complication? Such may be your DIY Weekly Reminder Circuit! The LED Flash Alert, along with the LDR and a day counter, may all combine into a low-power reminder to take out the trash, water the plants, or return that overdue library book. Once programmed, it blinks an LED to remind you on the same day of every week and will continue to do so until the reset button is pressed. Well, here is how the Digital DIY…

relay switch circuit

In this tutorial, you will learn how to make your relay switch circuit for Arduino in a few easy steps. We often see many electronics hobbyists especially Arduino users buy expensive relay modules instead of building their own. The general price of the relay module found in the market is about $2 but you can make your own for less than $0.70. In the tutorial Relay Switch circuit for Arduino, you will learn Relay and Operating principle Pin Identification of Relay Component value calculation and choosing the best for your…

touch switch circuit using bc547

Today, I have come up with another simple but very applicable project ‘Touch Switch Circuit using Transistor’. With this simple project, you can modify your existing electrical/ electronic appliance with a modern touch facility. A few days earlier I bought a reading lamp from one of the Chinese stores, the design of the Chinese product is quite impressive. The thing that motivates me to write this post is touch facilities i.e. you can on and off the lamp by simply touching the touch plate. The circuit posted here used two…

opto reflective sensor circuit using 555 ic

The DIY project posted here is of Opto Reflective Sensor using 555 IC and TCRT5000 module. These sensors are photoelectric sensors, which signifies that they rely on photo or light and do not need to be in contact with any other objects to sense. When a beam of light between the reflector and light sensor is interfered, that is when the sensor sends electrical signals. These electrical alerts are the information to the output unit. These days opto reflective sensor is used in various projects like proximity sensing, position detector,…
