Build a DIY IR Remote Controlled Arduino Lego Car Build a DIY IR Remote Controlled Arduino Lego Car Who has never dreamed of an Auto RC or better yet build one? With an old Lego set found in my junk, I've been trying, in recent days, to create a small RC car controlled by a IR remote control. The result will not be the the best performance because the remote control is not a good solution for long distances, as reception can be disturbed may not respond properly to commands. What do we need? Ingredients: Arduino Nano o UNO x1 Stepper motor x1 Servo Motor  x1 IR receiver module + Remote A lego Set with at least 3 wheels Assembling Let's connect all the modules to the Arduino in the following way:  Servo Vcc  ---  Arduino 5V  Servo GND ---  Arduino GND  Servo Data  ---  Arduino D5 Stepper Driver Vcc  ---  Arduino 5V   Stepper Driver GND --- Arduino GND  Steppe...

Show Temperate and  Umidity on an OLED screen 128x64 pi Show Temperate and  Umidity on an OLED screen 128x64 pi Living on an island I'm used to a fairly high humidity rate, especially in summer, the evening is almost unbearable. I was curious to know how much moisture saturation (%) was in my house, then in the future logging data on an SD card to compare the data with the dehumidifier switched on and not ..... but we will talk about this later on! Today we talk about how to display data on an OLED screen of the smallest size of just 0.96 " Let's Prepare the Soup What you need: Arduino nano  (or any other you have available) OLED Screen 0.96" DHT11  module Cables  F-F  type (or M-M in case on Arduino UNO) Wiring Up Now let's connect the modules with our Arduino Nano. Having Male Pin on Arduino and Modules I do not need a Breadboard as the links will be direct. If in your case it is diff...

Use a Telegram Bot to receive data from a Thingspeak channel Use a Telegram Bot to receive data from a Thingspeak channel Lately I've been playing around Telegram and its infinite functions, as, the very interesting one of the Bots. Having, in the past, linked an Arduino UNO to a Thingspeak channel, I wanted to write a script on my RPI Zero to program a Telegram Bot to allow it to respond some simple commands.  Not finding any guide around (or at least that I seen) I decided to post a little guide on my own here. ASSUMPTIONS: That you have a Public or Private channel on Thingspeak where to retrieve data from. That you have a machine where Python 3 runs Ex RPI What You Need:  A Telegram Account and a Bot on it Thingspeak  Account Raspberry Pi  To create a bot you'll need to add "@BotFather" to Telegram and send him a message "/newbot", once all data needed is inserted (it is very easy just follow BotFather...
