  22. Hello guys, im a 17yo student that loves electronics and i started working on custom tv-b-gone based on arduino version with rechargeable battery and i needed pcbs for it. Firstly i ordered pcbs(on the left) that were $3 PER PIECE and then i found out for JLCPCB. They have amazing offer of 10pcs 10x10cm pcbs for $2!! I could fit 6 tv-b-gone boards on one 10x10cm pcb and multiply that by 10 and you get 60 pcbs for $2!!! When i first ordered i tough that its just a low quality board but when i received them in 2 weeks (which is really fast) i was SURPRISED by QUALITY for that LOW PRICE.
  23. The very first program you write when you start learning a new programming language is: "Hello World!". The program itself does nothing more than printing a “Hello World” text on the screen. So, how do we get our Arduino to display the "Hello World!"? In this video, I will be showing you how to get started with the small 0.91 (128x32) and 0.96 (128x64) I2C OLED displays. There are 100s of tutorials on the web explaining the same thing in different ways, but I couldn't find one that tells me all about the OLED display and how to use it in different scenarios. It took me some
  24. Introduction ---------------- Hi Friends, I am back again with another Arduino based home automation project. This time I am trying to make my partner's life easy by installing a collision avoidance system in the garage to help her park the car safely without hitting the garage wall. So, in this video, I am going to use an ultrasonic sensor to calculate the car's distance from the garage wall and display it using green, yellow and red LEDs. The color of LEDs indicates whether to keep moving, slow down, stop or go back. The total cost of the project is around $20 - $25.
  25. Hi Everyone, In this tutorial I am going to show you how to charge a Lithium 18650 Cell using TP4056 chip utilizing the solar energy or simply the SUN.
