IR remote control Reference Design 3c2m thumbnail
This is a schematic of an IR (infrared) remote control system. It's built around a Microchip ATTINY2313 microcontroller (U1) and boasts five push-button switches, an indicator RED LED and an electret buzzer for user interaction. An ISP header provides programming capabilities. The project is battery-powered and implements boost converter TPS613222AD (IC1) for stable power supply. #project #Template #projectTemplate #lock #keypad #arduino #attiny2313 #TPS613222A #ISP #buzzer #referenceDesign #simple-embedded #microchip #template #reference-design
