37mm DC Metal Geared Motors with Encoder ₹ 1,695.00 ₹ 3,425.00
Measuring 37 mm (1.46″) in diameter, these 12V and 24V motors are capable of offering huge amounts of torque in a reasonable package. They are available in a range of gear ratios.  With quadrature encoders added to the micro metal gearmotors (with extended back shaft), these motors use a magnetic disc and hall effect sensors to provide 11 counts per revolution of the motor shaft. The sensors operate from 3.3 V to 5 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. NOTE: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

4*4 Matrix Keypad Keyboard Module ₹ 59.99 ₹ 149.95
The 4 x 4 matrix keypad usually is used as input in a project. It has 16 keys in total, which means the same input values. The 4 x 4 Matrix Keypad Module is a matrix non-encoded keypad consisting of 16 keys in parallel. The keys of each row and column are connected through the pins outside – pin R1-R4 as labeled beside control the rows, when L1-L4, the columns. A 4×4 matrix keypad consisting of microswitch buttons. The module has four holes 3mm (M3) holes for mounting. The pin designations on each PCB are shown on each PCB. Four pins are thus used as an ‘x’ coordinate and the other 4 as a ‘y’ coordinate.The module is already equipped with soldered pin headers (rotated 90 degrees). First test whether any key is pressed down. Connect power to rows, so they are High level. Then set all the rows R1-R4 as Low and then detect the status of the columns. Any column of Low indicates there is key pressing and that the key is among the 4 keys of the column. If all columns are High, it means no key is pressed down. Next, locate the key. Since the column in which the pressed key lies is identified, knowing the line would finalize the testing. Thus, set the rows as Low in turns until any is unveiled accordingly – other rows will still be High.Now the row can be identified. Detect the status of each column in turns. The column tested Low is the one intersecting with the line – their cross point is just the key pressed. Specifications Resources Datasheet Library  Sample Code
