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.
