These Jumper Wires are great for creating circuits between your microcontroller and the breadboard on the bots Reusable for fast build a prototype of an electronic circuit.  Soldering is not required.

Wires are flexible, durable, reusable, easy to trace, easy to connect and disconnect.

With these Jumper wires you can modify or revise the circuits easily.

PIR infrared sensor module is based on infrared technology. High sensitivity, high reliability, low power consumption, low voltage operation mode. It’s Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc. Widely used in various auto-sensing electrical equipments for security, automation and lighting control systems because of its unique property of detecting the movement of infrared emitting objects like human bodies. This sensor is equipped with Fresnel lens for improving the detection pattern. All you have to do is give the supply voltage and leave for about a minute to stabilize. Any movement detection causes the sensor output to go high (3.3V). This sensor can be easily used for 220V automatic lighting systems with the help of a simple relay circuit.   

This TP4056 1A Li-ion lithium Battery Charging Module with Circuit Protection – Micro USB is a tiny module, perfect for charging single cells that don’t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 5V 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.

It is an 8 Channel Isolated 28V 10A Relay Module, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other types of equipment with large current. Relay output maximum contact is AC250V 10A and DC 28V 10A. One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use.

This Relay is used for wide variety of AC & DC applications like Home Automation configured, Solenoids, Motors, lights, fans, heavy load device, home appliances & controlling higher current loads from microcontroller development board.
