Arduino MPPT Solar Charger Shield

20160119_projekte_028

Lukas Fässler has designed a MPPT Solar Charger Arduino Shield and document it on the link below. A Solar MPPT charger is used to convert the solar panel voltage to the optimal voltage for charging a battery in the most efficient way. This way the solar panel works on the maximum power point and thus delivering maximum power to the battery.

The basic idea behind an MPPT solar charger is simple. A solar panel has a certain voltage (in the region of 17 to 18 volts for a 12 volts panel, somwhat dependent on temperature) at which it provides most power. So as long as the battery needs charging, you want to pull just as much current to reach this voltage. But once the battery is full you need to avoid overcharging the battery. So you want to maintain a maximum voltage for your battery (somewhere around 13.8 volts for a 12 volt lead acid battery) and no longer care about the pannel’s voltage.

25 Useful Arduino Shields That You Might Need to Get

List-Arduino-Shields-Thumbnail

Rui Santos @ randomnerdtutorials.com has compiled a list of 25 useful Arduino Shields that you might want to use on your next projects. The list includes Ethernet shield, Relay, Motor, LCD and many more.

Arduino shields are boards that will expand the functionalities of your Arduino. You just need to plug them over the top of the Arduino board. There are countless types of shields to do countless tasks.

AVR Programmer Shield

ohneschuh @ instructables.com has build a Arduino Shield that is able to program spare ATmega328 and ATtiny85 mcu using the ISP sketch.

Beside my Arduino instructables I also use pure ATmega328 and ATtiny85 microcontrollers. To program them I normally used a breadboard and the ArduinoISP setup with an Arduino UNO or NANO. But this was not the best solution.

So I build this programmer shield in my typical stripboard layout: Only straight lines – no crossings!

by Matej Blagšič @ instructables.com:

My father asked me to do a little project with Arduino that would send an e-mail when a push button is pressed or anything, can be based on temperature reading, so make sure you watch my previous instructable on that or to send that something has closed up on the distance sensor. Be sure to watch those tutorials on my profile.

MOVI, a standalone speech recognizer shield for Arduino

20150701024028_MOVI

MOVI is an offline speech recognizer and voice synthesizer that adds voice control functionality to any Arduino project

MOVI stands for My Own Voice Interface! It is the first standalone speech recognizer and voice synthesizer for Arduino with full English sentence capability:
Up to 200 customizable English sentences.
Speaker independent
Standalone, cloudless and private
Very easy to program

MOVI provides an alternative to buttons, remote controls, or cell phones by letting you use full-sentence voice commands for tasks such as turning devices on and off, entering alarm codes, and carrying on programmed conversations with projects.

MOVI is plug and play! Connect the shield to your Arduino Uno or compatible board, connect an optional speaker, and you’re ready to go.
