Arduino Robotic Arm Project – Working The mini-robot arm uses four servomotors to move the arm. Servomotors are controlled by Arduino and connected to the PWM pin of Arduino. There are eight buttons in the android app. Out of these, four buttons are used to control the four servo motors...
Circuit and Hardware: Circuit Diagram for this Arduino Audio File Player is simple. The complete circuit diagram is shown in the Image below. As we know our audio files are saved into the SD card, hence we interface a SD card reader module with our Arduino. The Arduino and SD card commun...

The timing diagram of HC-SR04 is shown in the figure below. Circuit diagram. Full circuit diagram of the ultrasonic range finder using arduino is shown in the figure below. Trigger pin of the ultrasonic range finder module is connected to digital pin 0 of the arduino. Echo pin of the ultr...
This project focuses on building an Arduino Based Voice Recorder, which can also be abused as a spy bug. Our spy bug uses a small microphone to record the voice and it stores the recorded voice onto an SD card.
The basic circuit for the connection of the CTs to the Arduino is shown in the attached circuit diagram. The LCD screen shield already picks up on the analogue inputs but only A0 is used by the shield for the button inputs. Simply solder the five leads from your current sensors onto the...

Fire Alarm Circuit Diagram and Schematic Build your own fire alarm circuit Timer IC NE555 (IC1) is wired as an astable multivibrator oscillating in audio frequency band. Switching transistors T1 and T2 drive multivibrator NE555 (IC1). The output of IC1 is connected to npn transistor T3, which...
GND to arduino gnd VIO to arduino 5v (not sure if this is really necessary, @yba2cuo3 ?) OA1, OA2, OB1, OB2 to the motor GND to ground VM to 12v power in Right side Do not connect PDN UART (NC, PDN), CLK, EN to anything ...
We will utilise the Arduino IDE for software development and implementation. Previously we designed the simple stereo Fm receiver circuit and FM Receiver Circuit. This time, our primary goal is to design an affordable, compact, lightweight, and portable battery-operated Remote Controlled Stereo FM ...
