Door Bell kit

A kit of parts for you to build a 'ding-dong' door bell.

While creating circuits from discrete parts and carefully planning out glue logic can be fun for some makers, it can be a pain for others. This kit allows you to create a fully working door bell based around the M602 which perfectly demonstrates how some scenarios can justify a specialised IC.

• Component count: 18
• Includes high quality printed circuit board (PCB)
• Downloadable Electronics Construction Manual includes sections on how to solder and how to identify and mount all types of components on to the printed circuit board
• Downloadable instructions include information specific to this kit including circuit diagrams, schematic diagrams and explanations, 'how it works' circuit descriptions as well as component identification and constructional notes
• This circuit requires a power supply between 3 and 4V to operate correctly, so 2x AA batteries, not included, could be used. Alternatively, the Simple Power Supply kit, not included, could be used as it has a 3.3V output
