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.
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.
OPTIC ENCODED STEP MOTOR PROTOTYPE
Basic step motor are quite expensive and need step controllers modules as well. Here we're going to build a small and precise optic encoded step motor using optic switches. Encode the steps and calculate the rotation degree.
MAKE IT SOUND. WTV020-SD SOUND MODULE
If you have a small microcontrolled project and you want to use sounds this might be the best and chepper way to do it. Upload ad4 files to a sd card and play the tracks using Arduino control. You can easily make a talking robot.
ANDROID APP + BLUETOOTH + ARDUINO CONTROL
We will create a new App in AppInventor tool from Google. Next we will establish a bluetooth connection between an android smartphone and the arduino and start sending data in order to control our Arduino's outputs.
HOW TO BURN THE BOOTLOADER TO A ATMEGA328P AU
New microchips are empty, they usualy don't have enything burned in their memory. Without a bootloader the chip won't understand any of the code that you are sending to it. You have to burn a bootloader to it first and doing that to a smd chip is quite tricky.
MULTI CHANNEL RC TRANSMITTER
Using just 4 potentiometers, an Arduino microcontroller and a NRF24 radio module we will create 4 channels and send the analog readings of those 4 potentiometers to another NRF24 module used as a receiver.
RADIO FREQUENCY CONNECTION 433MHZ
Small example of how to use two 433MHz modules to comunicate between arduinos. Easy and fun.
MULTIPLE CHANNELS RADIO RECEIVER
Build a fast and powerful radio receiver using low cost module. Connect the arduino, upload the code and star receiving data. You can build your own 32 channels radio controller.
I2C SERIAL LCD COMUNICATION
This type of LCD normally uses about 7 pins to comunicate with the miorocontroller. Using a i2c serial comunication that noumber gets down to 2 pins : SDA and SCL
OBTAIN DATA FROM A MPU6050 MODULE
We will make a small code in order to obtain the acceleration and rotarion values drom a MPU6050 module. Doing a little bit of math we can calculate the inclination angle.
