Assorted Resistor Kit for Arduino Starter Projects

The TecnoMate Assorted Resistor Kit is the backbone of any electronics workbench, specifically curated for those working with Arduino, Raspberry Pi, ESP32, and standard 8051 microcontrollers. Every circuit requires precise current control, and this kit provides 600 high-quality metal film resistors to meet that need. Unlike cheaper carbon film alternatives, these metal film resistors offer a tighter ±1% tolerance and lower noise, making them ideal for sensitive analog circuits and digital logic alike. ### How It Works Resistors are fundamental components that implement electrical resistance as a circuit element. In your projects, they are used to reduce current flow, adjust signal levels, divide voltages, and bias active elements. This kit covers the full spectrum of common requirements, from low-resistance values used in power LED circuits to high-resistance values necessary for pull-up/pull-down configurations in logic gates. ### Key Features and Organization The kit is organized into 30 different resistance values, with 20 pieces per value. Each value is clearly labeled on paper strips, saving you the time of squinting at color codes during a build. The 1/4 Watt (0.25W) power rating is the standard for breadboard-friendly prototyping, fitting perfectly into standard 0.1" pitch breadboards and perf-boards. ### Typical Projects Use these resistors for current limiting in LED indicators to prevent burnouts, creating voltage dividers for sensor interfacing (like connecting a 5V sensor to a 3.3V ESP32), or establishing reference voltages in Op-Amp circuits. They are also vital for terminating bus lines in I2C or SPI communication to ensure signal integrity. ### What’s in the Box - 600 Pieces total (30 values x 20 pcs each) - Values included: 10Ω, 22Ω, 47Ω, 100Ω, 150Ω, 200Ω, 220Ω, 270Ω, 330Ω, 470Ω, 510Ω, 680Ω, 1KΩ, 2KΩ, 2.2KΩ, 3.3KΩ, 4.7KΩ, 5.1KΩ, 6.8KΩ, 10KΩ, 20KΩ, 47KΩ, 51KΩ, 68KΩ, 100KΩ, 220KΩ, 300KΩ, 470KΩ, 680KΩ, 1MΩ.
