This uses a buck converter as a 5V Output to charge the battery(Li Po/Li-ion). And Boost converter for 3.7V battery to 5V USB output for devices needed 5 V. Similar to the Original system that uses Lead Acid Battery as an energy storage charge by either PWM or MPPT controller. And supply for 12V Devices. This One only…
https://youtu.be/DRDmLbAgXZc How often have you used a screen for hours, only to find your eyes feeling strained, tired, and sore? Especially with the pandemic we’re all working and studying using our computers more than ever before, and because of this eye care is even more important than normal. To protect your eyes when using…
Today we will make a room temperature monitor, which we can use to monitor our room from anywhere in the world and to do that we will use a BLYNK IoT plateform and we will use DHT11 to read the room temperature we will use a ESP8266 to access the internet and it will send…
https://youtu.be/uHfz4Hv_mSs I’m a huge Harry Potter fan, and one of the things I’ve always loved from the Wizarding World are the moving portraits. I have converted an old Kindle into a real-life moving portrait! More info
I bet unless you really use them, you may always be thinking of knocking them all out before using them in your project. Well, if you feel the need of having a simple relay module, with just the basic components, you are at the right place. In this tutorial I am going to show you…
With this project I want to demonstrate the idea of a Turing machine with as much clarity as possible. I tried to build a machine that is simple to program and easy to understand. I guess that was my lofty goal for this project. The brain of the project is an Arduino Mega. More info
This project helps make your day a little easier if you’re a remote worker using Slack. I’ll show you how to build it using an ESP8266 wifi board. Don’t miss the video above for the overview. More info
We ensure social distancing with an audible and visual beacon that alerts you when you’re getting too close to a store counter, kiosk or counter. Since the “restart” after COVID-19 and the various Phase 2, Phase 3 and who knows what else, the expression “social distancing” has entered the common language and also our life…
On this litte instructable I will show how to create a simple RFID reader with TFT output for wall mounting using an ESP32. It’s easy to extend this simple design for more complex application and wireless data transmission. More info
In this project we will see the difference between a coin acceptor and a servo using an Arduino nano to drive them. More info
Today I am going to show you, how I build a “Racing Game Simulator” with the help of Arduino UNO. The working is very simple Arduino is use as a HID device that can communicate between computer and external componentdevices More info
Let’s combine the Fishino UNO power with the convenience of Google Home voice assistants, so that we can forget about the remote control and manage various devices with simple phrases. With this project, we are going to exploit the new technological ecosystems that are populating our homes: the voice assistants. In particular, we will see…
