Description: Get 10 PCBs for Only $5 pcbway.com - The hand gesture controller makes it possible to control applications using hand tilt angle values. Actually, the hand gesture controller uses an accelerometer, it is possible to use it wherever tilt is provided and control projects. For example, controlling with head movements other than hand movements. It also allows you to do this control wirelessly. By the way, thanks to PCBWay for supporting many Maker and Robotics projects with free product support. Take a look at PCBWay and contribute to their support: pcbway.com/setinvite.aspx?inviteid=258713 Check out this article for all the details: instructables.com/Hand-Gesture-Controller-for-Robotic Get the PCB Gerber file and Schematic: pcbway.com/project/shareproject/Hand_Gesture_Controller_for_Robotic.html 📋 How It Works? The Hand Gesture Controller includes an accelerometer and it detects the motion by comparing the acceleration on any axis with set thresholds.The accelerometer can measure the static acceleration of gravity in tilt-sensing projects. The hand gesture controller acts as a transmitter, so a receiver circuit is required. The program works as follows, The X, Y and Z values provided by the ADXL335 sensor are read by the program and transmitted to the Receiver via the nRF24L01 module. The receiver compares these values with the min and max threshold values defined in the program. If the values satisfy the condition specified in the program, the function is executed. 📋 The hand gesture controller contains three main hardware: 1) nRF24L01 Transceiver Module (bit.ly/2Te7Awg - amzn.to/2REa4n8) The nRF24L01 + transceiver module allows two or more Arduino boards to communicate with each other wirelessly and remotely. A transmitter and a receiver circuit are required to provide communication. An address (array of bytes) is created for two nRF24L01 modules to communicate. It communicates over this address and transfers data. A popular library called RF24 is used to interface with the nRF24L01 transceiver module. RF24 Arduino Library for nRF24L01+ Module - github.com/nRF24/RF24 2) ADXL335 Accelerometer (bit.ly/2EC4jQq - amzn.to/3gbToNa) At the heart of the Hand Gesture Controller is a low-power three-axis accelerometer ADXL335. It can measure the static acceleration due to gravity in tilt-sensing applications.

The Pro Mini does not have a built-in USB input, so a serial converter (FTDI) is used to upload the source code. It is an easy process. 📋 Prototype (Printed Circuit Board): A printed circuit board was designed to turn the project into a useful prototype. Printed circuit boards are plates with conductive paths on the surface for mounting electronic circuit components. To get the PCBs, simply upload the shared "Gerber file" to pcbway.com and create an order. High-quality PCBs will arrive in a few days depending on the shipping address.
