This set of ceramic capacitors...
This set of ceramic capacitors includes the most commonly used values, from 100 nF to 10 uF. Capacitors are organized in a storage box, so you can easily carry them.
It includes the most common resistor values from 10 ohm to 1 Mega Ohm.
FSR402 Force Sensing Resistor with Amplifier Module
This pin header is great for prototyping PCBs. This single-row male 40-pin header can be broken into smaller strips with the use of a wire cutter to fit your desired application. It is an ideal connector for integrated circuits and PCB boards.
This product is an integrated circuit that contains a shift register that allows you to transform the information transferred through serial interface into information on the parallel interface. For example, you can use it in your projects where you want to control a large number of LEDs, with only a small number of pins on the microcontroller or Arduino.
