Matrix Membrane Keyboard 4x4 Modulo

This module specially designed for Arduino will allow you to generate a light of any color (RGB) quickly and accurately.
The LED Bulb Module RGB, consisting of an LED capable of creating any color using RGB, has a PWM voltage input with three pins. These are capable of shining in a wide range of colors thanks to the mixture of the three colors. primary (red, green and blue).
These types of diodes are called RGB and are made up of three red, green and blue diodes in the same package.
Thanks to the variation of the intensity of these three diodes, we can create a composition of colors. With this led you can handle more than 16.5 million colors.

It is very easy to make it work with an Arduino, PIC or any other microcontroller.
In its output pin we will be able to measure the PWM pulse width depending on the distance of the obstacle.

COB LEDs are built as a matrix of LEDs, that is, a concentration of LEDs in a silicone coated tablet. The advantages of LED COB: - a light output of up to 120 lumens / watt (twice as much as LED SMD)
- the light intensity is greater without the need to concentrate the beam of light
- greater durability
- opening angle of up to 160ºC
- multidirectional light Mount LED diode on a good heatsink, add some fan, this is necessary because you have to "remove" the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the placement centers. the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.

USB SALEAE is an 8-channel logic analyzer without memory, a maximum sampling speed of 24MHz (depends on the PC and the use of the USB bus).
It allows you to record and display digital data read on the computer.
Logic Analyzer 8-Channel 24MHz features:
- 8 channels
- 24MHz sampling frequency
- 1000M samples
- USB power
- USB 2.0 HiSpeed
- 5V supply voltage
- LED - power indicator
- LED - logic indicator 0-1 on channel 1
- USB connection
You can change the sampling frequency by hand: 24MHz, 16MHz, 12MHz, 8MHz, 4MHz, 2MHz, 1MHz, 500kHz, 250kHz, 200KHz, 100KHz, 50KHz, 25KHz.
Works with TTL levels: low level from -0.5V to 0.8V and high level from 2V to 5.25V.

The module is based on a touch sensitive IC capacitive touch switch module (TTP223B).
In the normal state, the module produces Low power consumption. When a finger touches the corresponding position, the module output is high, if not touched for 12 seconds, it switches to low power mode. Digital Touch Sensor B21 features:
- Low power consumption
- Input voltage: 2 - 5.5VDC
- Can replace the traditional touch of a button - Four M2 screws diameter 2.2 mm that position the holes for easy installation
- 3-pin control interface:
1- GND
2- VCC
3- Control signal (output pin)
- Power indicators: Bright green LED when the sensor is on
