RGB LCD Display Electromyography using Arduino + MyoWare Muscle Sensor

Measuring muscle activity that uses electric potential as an indication to know the health, and diagnose muscles to its present status is referred to as electromyography (EMG). Electromyography also assesses the condition of nerve cell (also called as motor neurons) that controls the muscles and can detect neuromuscular disorders. The reference design is a LCD display electromyography using arduino plus myoware muscle sensor from Adafruit. The reference design features the standard LCD 181 also from Adafruit Industries LLC with the use of I2C/SPI character LCD backpack. The design also uses the muscle sensor surface EMG electrodes. Read more

Ultrasonic Rangefinder Using Arduino Uno and PmodMAXSONAR

The rangefinder is a device that measures distance from the observer to a target being measured. The device uses a sensor as the method of gathering measurements of distance, such as ultrasonic, laser, and radar. The circuit is a DIY rangefinder using a PmodMAXSONAR ultrasonic sensor, an Arduino UNO, and a 16x2 LCD module. The ultrasonic sensor has an effective detection range of 6in - 255in. It can detect objects within 1in up to 20ft away. The PmodMAXSONAR can send range data in three methods: UART, analog and PWM. Read more

BTN8982TA DC Motor Controller for Arduino Uno

The BTN8982TA is a half bridge DC motor controller. It is composed of a driver, a p-channel high-side MOSFET, and an n-channel low-side MOSFET. The built-in driver makes the device easy to be interfaced with a microcontroller. It features logic level inputs, slew rate adjustment, diagnosis with current sense, dead time generation, over-temperature protection, under-voltage protection, overcurrent protection and short circuit protection. The BTN8982TA can be combined with other BTN8982TA to form H-bridge and 3-phase drive configurations. Read more
