This is a mini project I made for fun. It was done at the beginning of this year and I thought I should share the story behind the making of this. It’s a cactus that tweet when it needs water :P. The idea started as an inspired project. I was watching a ted talk called How Arduino is open-sourcing imagination.
Our project utilizes two sensors to determine how optimal a plant’s environment is. We will be gauging the moisture in the soil and access to sunlight to output a quantifiable rating of the environment. The output will be in the form of LEDs that light up, where each LED corresponds to each quality, and the…
https://youtu.be/2FcOQE6c_SA Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips, so the USB port is converted to a virtual COM port on the computer. The…
https://www.youtube.com/watch?v=bGl29tdzQ-s&t=3s&ab_channel=maker.moekoe Hello makers, it’s maker moekoe! Flexball is based on a flexible PCB which is equipped with 100 WS2812 2020 addressable LEDs. It is controlled by an ESP8285-01f – the smallest ESP based module by Espressif. Additionally it has an ADXL345 accelerometer sensor on board. Original idea was to display text messages on that round…
. The objective of this project is to build an Arduino voice shield to empower thousands of voice related applications! All this mostly thanks to an integrated ISD1790PY chip. This particular voice/TTS feature can be useful to integrate voice messages in alarm systems, to implement generic I/O controls in home automation or even in home…
Instructables user MusaW has recently released a detailed guide to create a four leg (quadruped) robot using SG90 servo with servo driver and all controlled using WIFI Web server via smartphone browser: the total cost of the robot, including electronics and 3D printed components, is around US $55. There is a lot of NodeMCU variant in…
In this last post of the LoRa series we will see how to use the board, so to create a network composed of addressable and safe nodes. Semtech’s SX1278 integrated circuit, on which this shield is based, allows for a sophisticated and efficient communication in the LoRa (Long Range transmission) technology. This communication is…
