Description:-
The MT8870 Tone Decoder is a kind of common used multifrequency decode IC product developed by the MITEL company. It has a working voltage of 5V. It is a compete DTMF receiver. After it received the DTMF signal, it will divide the signal into high frequency group and low frequency group and send the signal to the digital decoder which can figure out the key value then send it to the outside Bus via four lines( Q1, Q2, Q3, Q4) as the binary form.

Description:
This voice record/playback device is based on ISD1820 chip, which can record/playback multiple-message. It can offer true single-chip voice recording, non-volatile storage, and playback capability for 8 to 20 seconds. For the sampling rate of 3.2KHz it can record for the total duration of 20 seconds.
Features:
If you want change the record duration, an external resistor is necessary to select the record duration and sampling frequency, which can range from 8 – 20 seconds (4-12kHz sampling frequency). This voice record module provides default connect to a 100k resistor through P2 by short cap. So the default record duration is 10s.

Description:
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter.

DS1307 is a real-time chip of DALLAS company,which adopt I2C protocal to communicate with SCM, and there was this kind interface on Arduino, therefore is very convenient to link with each other. DS1307 have a programmable waveforms output, it can be used to drive LED lights, or trigger a certain event as a break off, but be careful when you use it to take some kind of high power module. We design the real clock module to pin out the I2C interface of Ds1307 and programmable waveforms output interface SQW are connected, but usually we will only use the I2C interface to realize basic set the clock/read function. Note, this module must be installed on the battery can work normally. The battery is button batteries (type CR2032 will be better), the positive upward:
This tiny module embraces DS1307 time module, DS18B20 temperature module and AT24C32 storage module. DS1307 and AT24C32 are connected to IIC bus. And DS18B20 can be visited via DS pin.

Product Description
These displays were used in old Nokia 5110/3310 cell phones (before the smart-phone fad turned every cell phone into a TV). It’s a 84×48 pixel monochrome LCD display. These displays are small, only about 1.5″ diagonal, but very readable and come with a white backlight. This display is made of 84×48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well
To drive the display, you will need 3 to 5 digital output pins (depending on whether you want to manually control the chip select and reset lines). Another pin can be used to control (via on/off or PWM) the backlight – the backlight LEDs are wired to a transistor.
The display driver is a PCD8544 chip, and it runs at 3.3V so you’ll need a 3V supply handy (you don’t need that much current though, maybe 10mA tops). Logic levels must be 3V to prevent damage but we include a free level shifter chip so you can easily connect it to 5V logic such as an Arduino.

Introduction
PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.
