Then program your chip using an AVR-ISP programmer or similar outside the Arduino IDE.

You can install the custom ATTiny board manager and export the compiled binary (HEX file). I have used the Arduino IDE to write the code, however, you donвЂ™t need to use an Arduino board for this purpose. So I recommend you to look for quality and donвЂ™t select cheapies just for saving a few dollars!ДЄssembled PCB board of the infrared remote control switcher I had no problem with soldering the components. The PCBs have been fabricated by the PCBWay company and I can say the quality is just fine. Selected component libraries in the SamacSys Altium pluginДЇigure 5 shows the assembled PCB board. Figure 4 shows the selected components in the SamacSys Altium plugin.

Another option is to download the component libraries from and import them manually. Specifically, I used the SamacSys libraries for IC1, IC2, REG1, Q1вЂ¦Q3, and Q4, which you can consider the links in the references.

Supported Electronic designing CAD software by the SamacSys plugins

Figure 3 shows the supported electronic designing CAD software. SamacSys has provided plugins for the majority of electronic designing CAD software, not just for the Altium Designer.

So instead of wasting my time designing the libraries from scratch and increase the risk of errors and component mismatches, I used the free and IPC-rated ScamacSys component libraries and imported them right into the Altium PCB project using the SamacSys Altium plugin.

I did not have the schematic symbol, PCB footprint, and the 3D model of several components in this project. It is a neat piece of software that offers a user-friendly design environment and tons of useful features. PCB layout of the infrared remote control switcher boardДЄs I mentioned in the abstract, I used the Altium Designer software to design the schematic and PCB. ItвЂ™s a two layers PCB board and the majority of the componentsвЂ™ packages are SMD. P1, P2, and P3 are 2-pins right angle phoenix connectors.ДЇigure 2 shows the PCB layout of the infrared remote control switcher device. ISP is a 5-pins male header that is used to program the IC1 using an AVR-ISP programmer. D4, D5, and D6 are relay activation indicator LEDs and C1, C2, and C3 are used to reduce the relaysвЂ™ inductorsвЂ™ noises. R4, R5, and R6 are pull-down resistors and D1, D2, and D3 are protective diodes. Q1, Q2, and Q3 are the SI2303 N-Channel Mosfets that are used to switch the K1, K2, and K3 relays. C7 is a bypass capacitor and it has been used to reduce the supply noise. In this project, I set the clock to 8MHz-internal. The ATTiny85 is a cute chip! that offers 8K flash memory and can run up to 20MHz with an external crystal oscillator. SW1 is an SMD tactile push button and C10 debounces the push-button mechanical contacts. D7 is an SMD LED that indicates the good reception of the infrared signals (blinks). Q1 is the FDN360P P-Channel logic-level Mosfet that has been used to supply the D7. The output of the U1 has been connected to the PB3 pin of the IC1 and the gate pin of the Q4 Mosfet. This module is sensitive to supply noises, so R7 and C6 build a low-pass RC filter to reduce the U1 supply noise even further. U1 is the VS1838 infrared receiver module. D8 indicates good supply provision and C8 and C9 have been used to reduce the regulatorвЂ™s output noises. IC2 is the TS2937CW-5.0 regulator that prepares a fixed +5V supply for the U1 and IC1. C4 and C5 have been used to reduce the noise. REG1 is the famous 7805 through-hole regulator chip that prepares fixed +5V for the relays. Schematic diagram of the infrared remote control decoder/switcher board As it is clear, both the decoding and switching tasks are done just by one 8-pins ATTiny85 microcontroller. So letвЂ™s get started and build this puppy!ДЇigure 1 shows the schematic diagram of the device. The device works stable and reacts well to the transmitted IR signals. I also used the Siglent SDS2102X Plus/SDS1104X-E to analyze the IR signals. I used Altium Designer 21.4.1 and the SamacSys component libraries (SamacSys Altium Plugin) to design the Schematic and PCB. The load switching mechanism (momentary ON/OFF, toggling. Each relay can handle the currents up to 10A. The device can record up to three IR codes in the EEPROM memory and switch 3 separate devices. I have used an ATTiny85 microcontroller as the heart of the circuit. So we can use this feature in a variety of applications without buying a new IR remote control and expensive hardware, such as turning ON/OFF the lights, opening/closing the curtains. In this article/video, we learn to build a device that can decode (almost) any IR remote control and use the instructions to switch the relays (loads). The majority of home appliances are controlled using infrared remote controls. Infrared remote controllers are everywhere around us.
