Learn how to make an Arduino compatible microcontroller circuit on a breadboard

http://makezine.com/projects/build-a-mintronics-mintduino/

The MintDuino is perfect for anyone interested in learning (or teaching) the fundamentals of how microcontrollers work. It will have you building your own microcontroller from scratch on a breadboard, and then easily programming it from almost any computer via the Arduino programming environment.

Unlike pre-built microcontrollers, the MintDuino demonstrates the specific relationship between the wires, resistors, capacitors, and integrated circuits that enables you to program the microcontroller from your computer. After building the MintDuino, you’ll have a much better understanding of how microcontrollers work, and how electronics can interact with the physical world.

LM2596 Step-down Adjustable Power Supply Module CC-CV LED Driver New | eBay

http://m.ebay.co.uk/itm/370972680104?cmd=VIDESC&gxo=true

 

• Particularly suitable for LED driver
  
  *High-power LED constant current drive
  
  *Lithium battery charger (including ferroelectric)
  
  *4V, 6V, 12V, 14V, 24V battery charger
  
  *Nickel cadmium, nickel metal hydride battery pack charger
  
  *Solar panels and wind turbines

• Specifications:
  
  *Module Properties: non-isolated constant current and voltage module
  
  *Rectification: non-synchronous rectification
  
  *Input voltage: 7V-35V
  
  *Output voltage: 1.25V-30V
  
  *Output current: adjustable maximum 3A
  
  *Conversion efficiency: 92% (the highest)
  
  *Switching frequency: 150KHz
  
  *Output ripple: 50mV (max) 20M bandwidth
  
  *Load Regulation: ± 0.5%
  
  *Voltage Regulation: ± 2.5%
  
  *Operating Temperature: -40 ℃ to +85 ℃

• Battery use:
  
  * Make sure of the voltage and current of the battery you need to charge
  
  * Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
  
  * Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
  
  *Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
  
  * The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
  
  * Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries).

• LED Constant Current Driver Use:
  
  * Make sure operating current and Max operating Voltage of the LED you need to drive.
  
  * Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage.
  
  *Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer. To make sure the output current to the expected LED operating current.
  
  * Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED).

• The scope of application:
  Charging for lithium ion batteries: when the lithium ion battery voltage is low. If use the constant voltage charging directly. Due to pressure is too large, leading to the battery damage. So from the beginning to use the constant current charging. When charging to a certain, automatic switch back to the constant voltage charging.
