SparkFun Dog Treat Dispenser!By Robolab Technologies In More Info
We used the new SparkFun Load Cell Amplifier to make a load sensing doggie treat dispenser!
The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control, or simple presence detection.
