5% accuracy 1/4 watt resistors to get you started with your BEAM experiments.
This battery holder uses 3 AA cells to power your electronics, robotic or embedded project. You can do without, but MAN, when you need to hold 3AA cells, you'll need it!
This particular ATmega328P-20PU comes programmed and tested with the Arduino Firmware.
Need to hold a pair of AA batteries?
Standard 9V battery connector.
A simple but effective Grove water sensor. Expose the electrodes to a drop of water, and the signal drops very low. Can be used with both analog and digital ports.
This clever "spring-in-loop" sensor configuration is a well-proven touch-sensor for small to medium size robot applications
