Basic Electronic Components, DIY Learning and Robot Kits, SensorsL298N 2A Based Motor Driver Controller Module+100RPM Dual Shaft BO Motor (4pcs)+4 x 65mm Robot Wheel-Combo
- L298N Motor Driver Controller Module is a high power motor driver for driving DC and Stepper motors. It can control upto 4 DC motors, or 2 DC motors with directional and speed control. This motor driver is for robotics and mechatronics projects. The 150 RPM Dual Shaft BO Motor is a straight motor which gives good torque and RPM at lower operating voltages. It is a geared DC Motor. It is an alternative to metal gear DC motors. The 65MM Wheel is made up of standard grade rubber.
- L298N: Current Sense for each motor | Heatsink for better performance | Power-On LED indicator | Directional control | Speed control | High power motor || BO motor: Low density and inertia | Capability to absorb shock and vibration as a result of elastic compliance | Ability to operate with minimum or no lubrication | Relatively low coefficient of friction || Wheel: Car hub is reinforced nylon | Sturdy | Tire with sponge liner for more strength | With upgraded tire tread for greater friction
- Dimensions: L298N(LxWxH):44x44x28mm | Shaft length:7mm | Shaft Diameter:5.5mm | Motor(LxWxH):55x48x23mm | Diameter of wheel:65mm | Center Shaft Hole Diameter (mm):5.4 (Round edge) and 3.5 (Flat edge)
- The L298N motor driver is perfect for robotics and mechatronics projects. It can also be used for controlling motors from microcontrollers, switches, relays, etc. It is capable of driving DC and Stepper motors for micro mouse, line following robots, robot arms, etc. The BO motor is ideal for DIY enthusiasts. This motor set is inexpensive, small, easy to install and ideally suited for use in a mobile robot car. The 65mm wheel is only compatible with BO motor.
- L298N: Input Voltage:3.2V-40V DC | L298N Dual H-Bridge DC Motor Driver | Operating voltage:DC 5V-35V | Peak Current:2Amps | Speed Control:PWM | Control Signal input voltage range:0.3V≤Vin≤1.5V (Low), 2.3≤Vin≤Vss (High) | Max. power consumption:20W (when the temperature T=75℃) || BO Motor: Operating Voltage:3 to 12V | Current (without loading):40-180mA | RPM:100 | Output Torque:0.8 kgcm | Motor Design: L-shaped || Wheel: Loading Capacity (kg):2.5 | D hole For BO Motor (mm):6

PIR Motion Detector Sensor Module
The HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer.
It is used to sense the movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically-activated lighting systems. Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.
Features:
- Compact size
- Infrared sensor: dual-element, low noise, high sensitivity
- Blockade time: 2.5s (Default)
- Infrared Sensor with Control Circuit Board
- The Sensitivity and Holding Time Can be Adjusted
- Sensitive Setting: Turn to Right, Distance Increases (About 7M); Turn to Left, Distance Reduce (About 3M)
- Time Setting: Turn to Right, Time Increases (About 200S); Turn to Left, Time Reduce (About 5S).
