Buzzer alarm to convert electrical signals into intermittent acoustic signals in robotic devices and Arduino projects

A buzzer with a pulsating tone generator, after connecting the supply voltage (DC) in the range of 3V -24V, the buzzer generates an intermittent signal with a frequency of approximately 1 Hz. Application example: as a reverse alarm system for a car. 

It consists of a 16-character, 2-row display.
The display is compatible with the HD44780 controller.
Ideal for projects with ARDUINO.
You can use it with PIC, AVR, STM32. 16x2 1602 LCD display HD44780 Backlit Blue background features:
- LCD screen , 16 characters and 2 lines
- 5V power supply
- HD44780 compatible controller
- Backlit blue background, white letters
- Include an adjustable contrast pin
- Dimensions (mm): 80 x 36 x 12

It consists of three principles of induction of primary colors, if you know the composition of all types of color values, you can know the color of the test object.
For TCS230, a color filter is chosen, only a certain primary pass is allowed, it is stopped by another color. For example, when choosing a red filter, the incident light can only be stopped in red, blue and green, so you can get the intensity of the red beam of light.
For the same reason, the choice of other filters, can obtain the intensity of blue light and green light.
Through these three values, the color of the light can be projected onto a TCS230 sensor. Color Recognition Sensor GY-31 TCS230 TCS3200 features:
- Operating voltage: 3 - 5 VDC
- Model GY-91
- Chip TCS230 TCS3200

TB6612FNG controller, double H-bridge controller driver.
Allows to control up to 2 current motors continuous or bipolar stepper motor. It also allows to control a unipolar stepper motor configured as bipolar.
Ideal for projects with ARDUINO. You can use it with PIC, AVR, STM32.
An improved version of the L298N.
H-bridges are made up of MOSFET transistors, rather than BJT transistors as in the L298N.
The TB6612FNG has better efficiency and smaller dimensions than the L298N.
Controller TB6612FNG DC PAP motor features:

- Minimum operating voltage: 4.5 V
- Maximum operating voltage: 13.5 V (15V max)
- Maximum current: ± 3A per channel (1.2 A direct current per channel)
- Logic voltage: 5V
