    Best surface material for IR sensor touch table?

    Hey all, I am looking for the best (hopefully not crazy expensive) material that would diffuse LED light, but allow Infrared light to pass through and still pass back to an IR sensor? Making a multiplexed LED touch table and want it to light up and diffuse the "pixels" on the table, but not...

    ESP8266-01 with Arduino Nano issues

    Hello All, First, I know I can technically just flash things to the ESP8266-01 without the Arduino. I couldn't get that to actually work so I wanted to use the ESP8266-01 out of the box as a Wifi connection for my arduino nano. I have looked at a lot of tutorials for this setup and found they...

    Cheapest way to get data from multiple(100s) of sensors?

    Hey team, I am an electronics beginner/novice. Currently working with an Arduino UNO (though that isn't necessarily the only thing i'd want to use for this). I plan to have 100s of Reflective IR Sensors and want to be able to read from all of them at once in the cheapest way possible...

    My First Circuit Board Design - Will this print out well for a transfer?

    Hello All, I am putting together a circuit board for a project that will plug into my Raspberry Pi with a ribbon cable to provide motor control for 3 separate motors using a hobby battery that's 7.4v 1900maH. I have gone through 2 other iterations, attempting to build it first with all jumper...

    Can 7.4V 1900maH battery positive lead fry Raspberry Pi if attached to ground GPIO pin?

    I fried my raspberry pi somehow recently while working on my custom motor circuit that uses 2 L298N's for controlling the motors in my project. My source voltage comes from a 7.4V LiPo 1900maH Hobby Battery pack. While testing, I think i may have accidentally crossed the positive lead from the...

    Voltage Issue with Dual L298 ICs wired to Raspberry Pi

    Hello people, This is my first post here, so bear with me as I don't know the protocols and things you might need from me in order to get help with my circuit. Project: I am building an RC Tank with a turret that will fire nerf bullets. It uses a Raspberry Pi with a WiFi dongle in the USB...
