Make it your own

Every circuit here is a live project in Circuit Canvas, not just a picture. Copy this one and change a value, swap a part or move it to a stripboard: the schematic and the breadboard layout are linked, so a part added to one appears in the other.

Or start from a blank canvas and draw your own circuit, with thousands of ready-made parts.
