Out of stock170 pts Mini Breadboard SYB-170 White
[Breadboard and Zero PCBs] The SYB-170 Mini Solderless Breadboard is named for its 170 tie points. It has 17 columns of 10 holes, which are separated into two pairs by a central notch, and labeled 1 to 17. Each column is also labeled, with a letter from A to J to that they can be easily referenced in instructions ( like the squares on a chess board ). It has a peel and sticks adhesive backing as well as two mounting holes for M2 screws so you can anchor it down. This solderless, re-usable breadboard is made from sturdy ABS plastic housing. Great for prototyping, testing and creating add-on modules or new circuits. It’s standard nickel plated spring clips ensure longevity and firm grip. As a single unit, the PTBB-170W provides one large (170) tie-point IC circuit terminal strip. If you run out of space, the PTBB-400W can be pair with additional breadboards (below) to accommodate larger projects. Works with LEDs, transistors, diodes, capacitors, and resistors. Features : Use: experimental, testing, robot Matching jumper, diameter 0.8mm Accepts 20-29 AWG wire sizes. Adhesive-backed for permanent mounting. Phosphor bronze nickel plated spring clips Package Includes : 1 x 170 pts Mini Breadboard SYB-170 White
Out of stockPS2 Joystick Module Breakout Sensor
[Breakout Board] Dual Axis XY Joystick Module This is JoyStick Module PS2 Breakout Sensor very similar to the ‘analog’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers – one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is press down. With the help of this Joystick Module, you can measure position coordinates on the X and Y axis by moving the “hat”. It also contains a switch that is press-able by pushing the “hat”.It also contains a switch that is press-able by pushing the “hat” down. Similar to the XBOX controller. The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. This module uses the 5V power supply, and value, when reading through analog input, would be about 2.5V, a value will increase with joystick movement and will go up till maximum 5V; the value will decrease when the joystick is moved in other direction till 0V. Applications: 1. As square wave signal generator which generates a square wave signal 2. To provide a signal to the stepping motor driver 3. Adjustable pulse generation for chip use 4. Produce variable pulse signal, the control-related circuit (PWM dimming, speed) Module Description: Frequency is divided into three ranges: 1. XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz-999Hz 2. XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz-99.9KHz 3. X.X.X.(there is three decimal point): the smallest unit is 1Khz; the range 1KHz-150KHz Frequency Display Example: 1. ”100″ indicates that the PWM output pulse of 100Hz 2. ”54.1″ indicates that the PWM output pulse of 54.1KHz 3. ”1.2.4.” Indicates that the PWM pulse output 124KHz 4. Duty Cycle in the range:0 to 100 5. Three frequencies duty cycle is the same, all the parameters are non-volatile Features: 2.54mm pin interface leads Long service life and stable performance Standard interface and electronic building blocks Widely use in Arduino DIY projects Cross rocker as a two-way 10K resistor, with the rocker in a different direction.
