BreadBoard

Solderless Large BreadboardA breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). Because the solderless breadboard for electronics does not require soldering, it is reusable. This makes it easy to use for creating temporary...

LM35 Temperature Sensor

Description The LM35 series are precision integrated-circuit temperature sensors, with an output voltagelinearly proportional to the Centigrade temperature. Thus the LM35 has an advantage over linear temperature sensors calibrated in ° Kelvin, as the  user is not required to subtract a large constant voltage from  the output to obtain convenient...
