5% accuracy 1/4 watt resistors to get you started with your BEAM experiments.
TR3906 PNP small signal transistor, as used in most basic solarengine designs.
The 1N4007 1A 1000V DO41 Package Diode is ideal for back EMF protection
The CdS is a light sensitive resistor offering a range of 160 ohm to 700k sensitivity.
IR emitter and receiver in one package for close-range optical detection (sold individually)
Look, it's another voltage regulator! Look at it go! Vroom, vroom! (They go vroom, right?)
A 3.3V voltage regulator! AMAZING!
When the QTI sensor is over a dark surface, the reflectivity is very low; when the QTI is over a light surface, the reflectivity is very high and will cause a different reading from the sensor.
PICAXE-14M2 replaces the 14M, and offers the impressive suite of features of the M2 series in a small SMT package.
