RS485 Shield For Arduino Nano
Arduino Nano RS485 shield will help you to transmit and receive serial data using the twisted pair RS485 network. The module provides half-duplex communication. LED D1 indicates receive data, D2 Transmit LED, J1 jumper is optional and not in use in this application. DI/RE connected to...
Continue Reading50W Stereo Audio Power Amplifier based on TPA3116D2
I designed an audio power amplifier board based around the TPA3116D2. I choose the highest possible oscillator frequency of 1200khz. Many Chinese designs feature no output LC filter which may result in power losses and lower efficiency. Because of that, I choose higher grade...

Continue ReadingReflectance based Proximity Sensor using Si1102
This reflective sensor module is a high-performance 0-5 cm active proximity detector. The sensor can provide a range up to 50cm with higher current infra-red LED and current limit resistor R2, R4 used across IR LED. Because the sensor operates on an absolute reflectance threshold...
Continue ReadingMeasuring Water Flow Rate and Volume using Arduino and a Flow Sensor
Flow rate and volume helps tell the amount of fluid going into, or through a particular vessel. For certain process automation applications, this simple-sounding fluid measurement task is so critical to the success of the project that, failure to get it right, could bring the entire...
