Did you know you could use the Arduino to control the amount of current from a constant current source? Another great project from Henry’s Bench, this experimental project uses an MCP4725 Digital to Analog Converter, an LM358 Op Amp, an
What happens when you combine an arduino, a servo, and a rubber tentacle. Well, it could be madness, or it could be a knife wielding tentacle bot. Either way it’s a conversation starter, or ender. Become the Maker you
Thanks to the new Hardware I/O libraries, Processing is now optimized for the Raspberry Pi. This makes it much easier to use the Raspberry Pi I/O pins, and send data back and forth with a Arduino. Hardware I/O The Hardware
Many moons ago we built a Ethernet enabled clock that got it’s time updates from a Internet NTP Server. We have updated that project for WiFi,and added a rechargeable battery that can be recharged with a USB cable. Now just
Defend Your Base with Simple Circuits, Arduino, and Raspberry Pi Where will you be when the zombie apocalypse hits? Trapping yourself in the basement? Roasting the family pet? Beheading reanimated neighbors? No way. You’ll be building fortresses, setting traps, and
Long ago in a galaxy far away, we built a simple CdS Light Sensor (Sometimes called a LDR). Now with the real time plotting capability of Arduino 1.6.6, it’s even more fun! The original project requires no changes, just pick
