Hi guys, welcome to another Arduino tutorial. Today, I will be showing you how to use the 3.2″color TFT display with Arduino.
The display demand for every project is unique, a project may require just a simple, single color OLED display, while another project may require something bigger, all based on the function the display is to perform. For this reason, as a maker or electronics hobbyist, anyone needs to know how to work with as many displays as possible, that’s why today, we will take a look at how to use the super cheap, 3.2″ color TFT display with Arduino.

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 1.44″ colored TFT Display, is a SPI protocol based display with a resolution of 128 x 128 pixels. It’s capable of displaying up to 262,000 different colors. The module can be said to be a sibling to the 1.8″ TFT display, except for the fact that it is much faster and has a better, overall cost to performance ratio when compared with the 1.8″ TFT display. Some of the features of the display are listed below;
Size: 1.44 inch
Interface: SPI
Resolution: 128*128 pixel
Visual area: 1:1 square
TFT color screen, the effect is far better than other small CSTN screen
Drive IC: ILI9163
Fully compatible and alternative 5110 interface
Onboard LDO, support 5V/3.3V input voltage, the LED backlight, 3.3V input
For this tutorial, we will focus on demonstrating how to use this display with Arduino to display texts, shapes and Images.

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 something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.
The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

One thing we all always wish we could do when using any display is to load our own custom graphics, be it a logo, gif etc. In today’s tutorial we will show how to do just that on an OLED display using an Arduino.
OLED (organic light-emitting diode) display is a display based on light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles, and PDAs. OLED displays do not require a backlight because they emit visible light and can thus, display deep black levels and be thinner and lighter than a liquid crystal display (LCD).

Use PiSupply’s PaPiRus ePaper display to monitor your network with a Raspberry Pi.
Over the past few days I have been converting my “Speedtest-cron” code to work on the PaPiRus from PiSupply. Whilst going over the code, I decided to start a new Git Repository and rename this version to “PaPiRus Netapp”.

Measuring distance is so important in today’s world that things like driverless cars will be impossible without it, that description is probably enough to describe how important knowing the distance between two objects can be. For that reason, today we will be building a distance meter using the Arduino and the HC-SR04 ultrasonic sensor.
The HC-SR04 ultrasonic sensor is a cheap ranging sensor capable of measuring a distance between 20 – 400cm without contact and at an accuracy of up to 3mm. The sensor is made up of a transmitter and receiver with operating frequency of around 40khz. It uses the echo principle for distance measurement by emitting an ultrasonic wave of 40khz. If there is an object in its path, the emitted wave is reflected and the reflected signal is received via the receiver. The time elapsed between the transmission of the signal and the reception of the echo is then used to determine the distance between the sensor and an object in its path.

Our friends on educ8s.tv published a new video. Check it out.
In this ESP32 project video, we are going to use an E-Paper display and a DS18B20 temperature sensor to build a low-power thermometer. We are going to use the Arduino IDE to program to ESP32 board. ! It is a very easy project to build. It won’t take us more than 5 minutes so let’s get started!

Our friends at educ8s.tv uploaded a new video. It’s about Waveshare 1.54″ e-paper display:
Dear friends welcome to this Arduino E-Paper display tutorial. In this video, we are going use this small e-paper display with Arduino for the first time and talk about its advantages and disadvantages.
FPGAs are field programmable gate arrays which basically means they are reconfigurable hardware chips. FPGAs have found applications in different industries and engineering fields from the defence, telecommunications to automotive and several others but little application in the maker’s world. Mostly, as a result of being largely difficult and high cost as compared to the likes of Arduino, but the introduction of the ezPixel and other similar FPGA boards is making this a possibility.
Prototype modules.
The ezPixel board, by Thomas Burke of MakerLogic, is a small size FPGA based circuit board that can be used to drive up to 32 strings of WS2812Bs, for up to 9,216 LEDs in total, a very first of its kind. These WS2812B programmable color LEDs have been a phenomenon in the maker’s world, being used in various Led Lights and creating of various Light Artworks. These popular LEDs comes in strings that can be cut to any length, and only require a single wire serial data connection to control all the lights in the string individually, and multiple strings can be stacked together to create large two-dimensional displays.
ezPixel description.
Most WS2812B controller boards can be used to control up to hundreds of these LEDs, but not thousands of them. The ezPixel board is a perfect fit for applications that use thousands of these LEDs. The ezPixel board is powered by the Intel MAX FPGA, a single chip small form factor programmable logic device with full-featured FPGA capabilities, and it’s designed to interface with other Micro-controllers or any SPI/UART host device. The ezPixel board serves as bridge between microcontrollers and long WS2812B strings. A user sets the length of each string using simple commands that are sent via the SPI or USB/UART communication link.
The following below are the features of the ezPixel:
WS2812B Smart Pixel Controller.
Up to 32 Strings can be controlled independently.
Up to 9216 LEDs can be controlled.
Communication:
USB/UART Interface.
SPI Interface.
Read/Write Pixel Memory.
FPGA – Intel MAX10M08 FPGA.
Dimension:
1” x 3” (25mm x 76mm).
SPI Flash.
The ezPixel can run as a standalone display controller as a result of its serial flash memory chip, and this board is slated for a crowdfunding campaign in early 2018.
Erich Styger has a nice write-up on Waveshare e-paper displays:
I have used E-Ink displays in projects three years ago, but from that time the technology has greatly evolved. That time displays were hard to get, expensive and difficult to use. Now things seem to change with e-ink displays available to the maker market :-). I’m able to get a 128×296 pixel e-paper display for $10! And for little more money I can have displays with black/white/red colors!
