Arduino ambilight with WS2812 LED strip

We read the serial data from the Perismatic software via USB connection. The arduino generates the data for the LED strip and send it to the Din pin. The LEDs will change their color coresponding to the image on your screen.
Arduino power logger + Voltage and current

We read the current using a shunt resistor and basic ohm law. We amplify the voltage drop with and OPAMP and read that with an Arduino. Finally, we use an i2c display and print current, voltage, power and energy.
Arduino step motor slider - 3D printed

I've designed all the 3D parts for a camera slider. Using a step motor we can preciselly control the speed and direction of the slider. I've made a 3D case with a rotary encoded menu adn LCD inside for control.
ARDUINO RFID DOOR LOCK

Read an ID tag with an RFID module and Arduino. Detect if the ID is correct and open a servo motor. Using a master card, add new IDs. Error message if ID is incorrect.
DIY RADIO CONTROLLER ARDUINO+NRF24

Build a radio transmitter with 5 analog channels and 2 digital. Use the power amplified antenna and send 7 bytes of data. Receive the signal and create a PWM output foe each channel with range 1000-2000us.
PID TEMPERATURE ARDUINO CONTROLLER

Full Temperature PID controll with Arduino. Closed loop. See all the schematics, codes and examples here.

BRUSHED MOTORS ARDUINO DRONE

Usually drones have brushless motors. In this tutorial we will build a drone using Arduino but with brushed motors.
MENU WITH VOICE AND ROTARY ENCODER

Encode the position for the menu and scroll up and down. Select the with the special cahracter (arrow) and enter the menu. A different voice sound will be played for each selected menu usinf the DFplayer module.
HOMEMADE POV DISPLAY

Count real time while the propeller is spinning. Use interruptions for that and register control of outputs and draw a clock, text or any shape on the POV display.
ANDROID APP & ARDUINO BLUETOOTH RECEIVE

Create the Android App in AppInventor2. Next read data from sensor, potentiometer, etc. Send the data with Bluetooth connection HC06 module. Receive the data and create a Graph or control Screen components of the smartphone.
WHISTLING SWITCH

We will detech a whistle sound with a very easy microphone circuit. Then we measure the frequency and with a little bit of code we could switch on and off anything.
HOMEMADE ELECTRIC SCOOTER

Build your own ELECTRIC scooter using a huge brushless motor powered by a 120A ESC and controlled with arduino. See all the build steps and the scheamtics/codes.
VOICE CONTROLLED 3D PRINTED ROBOT ARM

Record your own voice commands. Each command will send a 2 bytes instruction to the Arduino. Receive those bytes and control anything with the Arduino.
WIFI YOUTUBE SUBSCRIBERS COUNTER

Using the ESP9266 WiFi module we connect to internet. Using the youtube ID and API key we ket the subscribers count an print the value on a 7 segment screen module.
3D PRINTED ARDUINO BASED RPM METER

We will build a simple Arduino RPM meter with an IR sensor. Print the measured value on an OLED screen. Extra push button for LOW power mode activation.
HUGE LED MATRIX ARDUINO & MAX7219

Using huge 1cm green LEDs we will create a 8 by 32 LED matrix and display text and unique icons using the arduino and the MAX7219 matrix driver. Easy to build and understand.
ARDUINO ANDROID APP BLUETOOTH RGB LED CONTROL

Learn how PWM with RGB leds work. Create the android App. Make the circuit connections and start a bluetooth connection. Send data and control the color of the LED strip. Awesome right?
ARDUINO REGISTERS CONTROL AND INTERRUPTIONS

First we will talk a bit about 8 bit registers of the arduinio, ATMEGA328p datasheet and how to find each register. Then we will see the difference between using Arduino functions or directly register control. Finnaly we will set the register of one timer of the arduino to make an interruption at 2KHz. Inside of that interruption we will create a sort of PWM signal using register control.
ARDUINO KEYPAD DOOR LOCK

My door lock is busted so I had to make my own. With a small 4x4 keypad we will insert a password. If correct a servo motor will open a slide door lock. If not an error will show up and we have to try again. The system also has a buzzer and an emergency open button.
MULTIMETER USING ARDUINO

We will see the basic step of a multimeter. Using simple codes we will be able to measure with quite precision resistence, capacitance, inductance, current and power.
