Hi guys, over the past few tutorials, we have been discussing TFT displays, how to connect and use them in Arduino projects, especially the 1.8" Colored TFT display. In a similar way, we will look at how to use the 1.44" TFT Display (ILI9163C) with the Arduino. The ILI9163C based...

4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. Very compact design that can fit on top of Arduino UNO. Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4...

Hi guys, in one of our previous tutorials, we built a real-time clock with temperature monitor using the DS3231 and the 16x2 LCD display shield. Today, we will build an upgrade to that project by replacing the 16x2 LCD display with an ST7735 based 1.8" colored TFT display. Apart from...

Hi guys, welcome to this tutorial. Today, we will build an mp3 player using an Arduino and the DFPlayer mini MP3 module. The DFplayer mini is a small, low-cost mp3 module with a simplified audio output that can be connected directly to a speaker or an earphone jack. The module can...

Hi guys, welcome to today's tutorial. Today, we will look on how to use the 1.8" ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or...

This board created for makers, who want to use various Arduino UNO shields with PIC micro-controllers from Microchip. Board facilitates the use of any 28 PIN DIP PIC microcontroller with or without crystal. Omit Y1 , C9 and C10 in case of internal oscillator . Project can also be used...

One of the major problems encountered when using push buttons and switches in digital electronics project is the problem of bouncing. When we press a button once it may register twice and when we press it four times, in a row, for instance, it may register just twice. This occurrence is...

Mini Isolated Power Supply is designed for CAN, RS-485, RS-422, RS-232, SPI, I2C, Low-Power LAN applications. The power supply provides +/- 5.50 V DC symmetrical outputs with load current 500mA from 5V DC input. The project is built using SN6505A IC from Texas instruments. The SN6505A...
