Make Wireless Pentesting Easy with ESP32-DIV
https://www.electronics-lab.com/make-wireless-pentesting-easy-with-esp32-div/
ESP32-DIV is a palm-sized wireless pen-testing device powered by an ESP32. It features an ST7735 TFT LCD display and can perform Packet Monitoring, Wi-Fi Scanning, Beacon Spamming, and Deauth Detection. The ESP32-DIV combines the powerful ESP32 microcontroller with an ST7735 TFT LCD screen, along with four microswitches, a buzzer, and a few additional switches making […]
Tiny TFT Graphics Library for ATtiny84
https://www.electronics-lab.com/tiny-tft-graphics-library-attiny84/
This is a graphics library for the family of small colour TFT displays based on the ST7735 and ST7789 driver chips. These are really nice displays; bright, colourful, available in a variety of useful sizes, and available at low cost from suppliers like Adafruit, AliExpress, or Banggood. This is a new project by David Johnson-Davies. […]
Using the 433MHz RF Transmitter and Receiver with Arduino
https://www.electronics-lab.com/using-433mhz-rf-transmitter-receiver-arduino/
While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where communication is one way (Receiving device cannot transmit and the transmitting device cannot receive). Several options […]
NIMO Clock – Recreating the look of a 60’s CRT display
https://www.electronics-lab.com/nimo-clock-recreating-the-look-of-a-60s-crt-display/
Recreating the look of a 60’s CRT display with small LCDs. By Paul Bricmont @ hackster.io: My design uses six 1.44-inch TFT LCD displays to display NIMO-style digits. These small LCD displays are cheap (around $3.50 US each) and use the ST7735 chipset and SPI bus. To drive the displays I’m using the Adafruit Metro […]
Color Detector Using TCS230 Color sensor and Arduino
https://www.electronics-lab.com/color-detector-using-tcs230-color-sensor-arduino/
Hi guys, welcome to today’s tutorial. In this tutorial we will look at how to use the TCS230 color sensor with Arduino. To demonstrate the ability of the color sensor, we will build a color detector system capable of detecting the color in front of the sensor and displaying that color on a TFT Display. […]
Arduino Real Time Clock with Temperature Monitor
https://www.electronics-lab.com/arduino-real-time-clock-temperature-monitor/
Hi guys, in one of our previous tutorials, we built a real-time clock with temperature monitor using the DS3231 and the 16×2 LCD display shield. Today, we will build an upgrade to that project by replacing the 16×2 LCD display with an ST7735 based 1.8″ colored TFT display. Apart from changing the display, we will […]
Using the ST7735 1.8″ Color TFT Display with Arduino
https://www.electronics-lab.com/using-st7735-1-8%e2%80%b3-color-tft-display-arduino/
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 […]
Bitmap graphics on an Arduino Touch Screen and other top Arduino Displays
https://www.electronics-lab.com/bitmap-graphics-arduino-touch-screen-top-arduino-displays/
In this video tutorial educ8s.tv shows us how to load bitmap graphics in our Arduino Touch Screen projects using Adafruit’s GFX library. The procedure that I am going to describe works with all the color displays that are supported by Adafruit’s GFX library and by the displays that use the TFTLCD library from Adafruit with […]
Adjusting clock with alarm, hygrometer & thermometer on 1.8″ ST7735 display
https://www.electronics-lab.com/adjusting-clock-alarm-hygrometer-thermometer-1-8%e2%80%b3-st7735-display/
Nicu Florica blogged about his adjusting clock with alarm, hygrometer and thermometer on 1.8″ ST7735 display: I use feature from article Another adjusting clock with alarm & thermometer using DS3231 on 1.8″ ST7735 display and change reading internal temperature of DS3231 with DHT22 sensor (AM2302), but you can use a cheaper and not very precise DHT11 […]
Choose The Best Display For Your Arduino Project
https://www.electronics-lab.com/choose-best-display-arduino-project/
Have you ever been unsure which display you should be using in your next project? This tutorial from educ8s.tv will come in handy for choosing the best display for your each and every Arduino project! There are lots of choices, so let’s talk about each one of them. Basically, you have three types of displays: […]
