Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Breadboard 400 Tie Point Interlocking Solderless - A breadboard comes in handy when you want your wiring connections organized.
This breadboard is what we usually called the full-size breadboard. The total number of pins it has is 400. 100 pins of it are for the power rails on both sides, having 50 each. The middle part where you make the connections of your components is Terminal Strips, having 300 pins. The pins are spaced by a standard of 0.1"/2.54mm so that jumper cables can sit beside each other.
It also has self-adhesive on the back for mounting, and interlocking parts so that you could have a cascaded breadboard.
One can find breadboards commonly in 3 sizes and shapes. 170 tie-points is the smallest one, whereas 400 tie-point breadboard (with power rails)is the mid-sized system. They're also larger 830 tie-point breadboards that feature power rails as well.
400 tie-point interlocking Solderless breadboard is quite beneficial to integrate smaller modules in robotic projects. It is useful in robotic applications to build circuits for small projects. The equipment brings two power rails on both sides along with a standard double strip in the middle. The size of the 400 tie-point interlocking Solderless breadboard measures 8.2 cm x 6.2 cm. Another fascinating feature is that users can pull the power rails off to make the unit as thin as 3.5 cm. This flexibility enables it to stick onto an Arduino protoshield.
Furthermore, the white-colored Solderless breadboard unites10 columns, 2 power buses, and 30 rows. It makes the unit to host 400 tie-points.On the back, you will find a self-adhesive. The unit incorporates interlocking parts to let you hook as many elements as you like.
The following are various features and specifications of the 400 Tie Point Breadboard –
400 Tie Point Interlocking Solderless Breadboard makes prototyping as easier affair an it implements jumper wires to develop electrical connections without soldering.
