Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Resistors are a crucial part of any circuitry. But sometimes when we need one, they suddenly disappear into thin air. The only way to solve that is to stock up and keep arranged systematically. Our brand new resistor pack comes with 2000+ pieces of various values of 1/4w metal film resistors. All of these resistors are in a tri-fold tape and labelled.
Specifications are as follows :
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, 1M
with 20 pieces each value.
