This TP4056 1A Li-Ion Battery Charging Board Type C with Current Protection is a tiny module, perfect for charging single cell 3.7V 1 Ah or higher lithium-ion (Li-Ion) cells such as 16550s that don''t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished.
Furthermore, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time.
 
Using the module:
Connect Type C cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
Connect cell to charge to B+/B- pads on the right-hand side of the module.
A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
Important! Disconnect load when charging
The red LED indicates charging in progress, the green LED indicates charging has finished.
Never charge your battery at a rate greater than 1C.

NOTE:
1. Ampere meter can only be connected to a 5v input end of the module.
2. It is better than the charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, a current of 400mAh is enough.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to the chip.
6. NO Reverse polarity.
Features :
Led indicator: Red is charging Green is fully charged.
Current Protection: Yes
Inversed polarity: NO.

How easy would it be to switch on your fan automatically as and when the temperature increases or decreases All you need to do is, set a trigger temperature at which the fan should switch on or off. Using W1209 module, which is highly functional and low cost can help you to invent such minor yet amazing automation in your home!
W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. It is an affordable, good quality thermostat controller. Thermostats are devices that sense the temperature of a system so that the temperature is maintained at the desired set point or near to it. NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. NTC thermistor has a negative temperature coefficient, which means the resistance decreases with increasing temperature. W1209 has an inbuilt embedded micro-controller, thus not much programming knowledge is required. The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures. The relay can operate at voltages up to a maximum of 240V AC at 5A or 14V DC at 10A to power on. The temperature is displayed in degree centigrade and with the help of 7-segment display and the relay, the state is displayed with the help of the LED present on the W1209 module.

1 Channel 5V Relay module is used as a switching device and as it is a single channel this module can control only a single circuit. Relay modules with multiple channels can control multiple circuits.

This module consists of 6 input-output pins i.e., Vcc, GND, IN, Common (COM), Normally Closed (NC) and Normally Open (NO). Vcc and GND are the two ends of the coil inside the relay. These pins are used to trigger ON/OFF the relay. Vcc is connected to 5V DC and GND is connected to the ground. At Input pin, we give a signal from a microcontroller to allow/disallow current to flow through the coil. Common is connected to one end of the device to be controlled. The other end of the load is either connected to the NC or NO. If the load is connected to NC then the device remains connected before trigger and if it is connected to NO then the device remains disconnected before trigger. The trigger voltage of this module is 5 V.

Devices operating on 10A, 250V AC and 10A 30V DC can be used as load devices for this module. When the trigger voltage is supplied the coil is turned ON and then the contact between common to NC is changed to common to NO. and when trigger voltage is not supplied to the relay the contact comes back to common to NC from common to NO.

This is LCD 1602 Parallel LCD Display that provides a simple and cost-effective solution for adding a 16×2 White on Liquid Crystal Display into your project. The display is 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight.

This is great blue backlight LCD display. It is fantastic for Arduino based project. This LCD1602 LCD Display is very easy to interface with Arduino or Other Microcontrollers.

This display overcomes the drawback of LCD 1602 Parallel LCD Display in which you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily in this product, an I2C adapter is directly soldered right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding.

The I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V.

If you already have the I2C adapter soldered onto the board like in this product, the wiring is quite easy. You should usually have only four pins to hook up. VCC and GND of course. The LCD display works with 5 Volts. So we go for the 5V Pin.

The values shown on the display can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.

This is Soil Moisture Meter, Soil Humidity Sensor, Water Sensor, Soil Hygrometer for Arduino.  With this module, you can tell when your plants need watering by how moist the soil is in your pot, garden, or yard. The two probes on the sensor act as variable resistors. Use it in a home automated watering system, hook it up to IoT, or just use it to find out when your plant needs a little love. Installing this sensor and its PCB will have you on your way to growing a green thumb!

The soil moisture sensor consists of two probes which are used to measure the volumetric content of water. The two probes allow the current to pass through the soil and then it gets the resistance value to measure the moisture value.

When there is more water, the soil will conduct more electricity which means that there will be less resistance. Therefore, the moisture level will be higher. Dry soil conducts electricity poorly, so when there will be less water, then the soil will conduct less electricity which means that there will be more resistance. Therefore, the moisture level will be lower.

PC817 Photocoupler IC has a transistor that is controlled based on light (photon). So this IC basically has an IR (infrared) LED and a photo-transistor inside it. When the IR LED is powered the light from it falls on the transistor and it conducts. PC817 IC is used to provide electrical isolation between two circuits, one of which is connected to an IR LED and the other to a phototransistor. The digital signal sent to the IR LED is reflected on the transistor, but there is no physical connection between the two. 

This comes in handy when you're trying to isolate a noisy signal from your digital electronics, so if you're looking for an IC to provide optical isolation in your circuit design, this could be the one.

Get your start in robotics and make things move! The MG90S is an upgrade of the SG90 with even more torque and speed than ever. It also has metal gears which means when the motor is in a jam, the gears aren’t likely to strip. And as a digital servo using a high-speed pulse train, a more detailed configuration is allowed.

You can expect this micro servo to rotate up to 90 degrees. You can expect it to operate the same as standard versions, but this micro servo is much smaller and can fit into tighter spaces. Even though it has metal gears, this tiny little servo weighs only 13.4g, so a good choice for smaller projects.
