A dc servo motor provides precise motion control, enabling accurate positioning and speed regulation in various applications. It consists of a rotary or linear actuator, which allows for such precise control of angular or linear position, velocity, and acceleration. It’s used in several sectors, including: Robotics Industrial automation Angular load positioning Avionics Automobiles A few…
How to design pick-and-place robot using Arduino
In this project, we’ll design an omnidirectional, moving pick-and-place robot. First, let’s cover how the robot is built. The robot’s build As shown in Figure 1, the robot consists of two sections: An omnidirectional moving platform A robotic arm The omnidirectional platform The robot is built using one circular wooden plate, three dc gear motors,…
How to design an automatic streetlight system using Arduino
In this project, we’ll design an automatic, energy-efficient streetlight system using Arduino. A streetlight will automatically turn on when the outside ambient light falls below a certain threshold, as evening turns to night. They turn off when sufficient light returns in the morning to conserve energy. So, these streetlights only power on when needed. The…
How to design a multi-use level indicator using Arduino
In this mini do-it-yourself (DIY) electronic project, we’ll design a multi-use level indicator that can measure multiple physical parameters like temperature, water, voltage, humidity, distance, and more. It consists of a bar-graph LED display that presents the measurements. Four main types of sensors are used to measure the different physical parameters, including the following LM35…
How LoRa can impact smart cities with parking sensors
In this article, we’ll configure a parking sensor using LoRa (long-range) devices. LoRa is a wireless communication technique derived from Chirp Spread Spectrum (CSS) technology. For this project, Arduino Nano is connected to an ultrasonic sensor, detecting parking occupancy based on distance measurements. When a vehicle enters or leaves a parking space, the ultrasonic sensor…
How to design a smartphone-operated door lock
In this project, we’ll design a unique door lock that can be operated without a keycard, input password, or biometric ID. A smartphone is the key to locking and unlocking the door via Bluetooth. This door uses a solenoid lock, which relies on a latch for electrical locking and unlocking. It also has LEDs to…
