IR Remote Tester

I play a lot with infrared remotes and Arduino using the IRemote library. Various remote controls use different codes, so I designed a device to read them easily. Print Settings Printer Brand: RepRap Printer: Prusa i3 Rafts: No Supports: No Resolution: 0.2 mm Infill: 20 % Notes: Prints easily without raft or support. The model is designed for ABS and accounts for ABS shrinkage. Steps to Manufacture Necessary Components Arduino compatible 5 V board which will fit this form factor. I used a BTE13-010A Pro Mini, which is cheap clone of Arduino Pro with ATMega168 5 V chip at 16 MHz, but you can use anything that runs on 5V. TSOP4838 IR sensor. 8x 7-segment display module based on MAX7219 to display result 30x70 mm prototyping PCB DC jack suitable for your power supply USB to serial converter for programming Electrical Connection The electrical connection is pretty straightforward, as there are just three modules to connect. Use the following pins of Arduino: 2 to LED display DIN or Data IN 3 to LED display CS or Load 4 to LED display CLK 5 to IR receiver DATA RAW to DC jack positive GND to ground on DC jack, IR sensor and LED display VCC to VCC on IR sensor and LED display Programming The code itself is also pretty simple. It reads the value and displays it as 8-digit hexadecimal number on the LED display. Mechanical Build The LED display and universal boards are held in place by M2.5 screws. The IR sensor is placed in the hole and sealed with hot glue. The parts of case are screwed together, again with M2.5 screws.
