This app is a AVR tutorial based on ATMEGA16 C language. It is suitable for hobbyist or engineering students. Learning AVR mcu is difficult. The learning curve is steep. The process including reading datasheet, writing code, building prototypes and troubleshooting. The most possible errors are the setting wrong value of registers. Now, AVR tutorial is the solution. The code wizard allow you to set the timer, UART, ADC, interrupt and peripherals by just a few clicks in setting. The proven C source code is generated automatically. Though the code wizard is based on ATMEGA16 mcu, it is easy to port to other ATMEGA mcu since the source code is highly structured Features • AVR architecture review • AVR asm mnemonics & C language • 21 demo projects including LED, buzzer, key switch, lcm16x2, ADC, etc • Code wizard for UART, timer, interrupt, ADC and external peripherals Features in PRO only • Support I2C eeprom 24C01 (128B) ~ 24C512 (64kB) • Support SPI eeprom 25010 (128B) ~ 25M02 (256kB) • Extra demo projects including led matrix 16x16, I2C eeprom, SPI eeprom • Code wizard for I2C eeprom, SPI eeprom, LCM128x64, etc Atmel® and AVR® are registered trademarks or trademarks of Atmel Corporation or its subsidiaries, in the US and/or other countries.

Capacitor
Easily determine capacitor values from color codes or calculate color codes from values. Supports both standard and SMD capacitors, providing quick and accurate conversions for electronics projects.
- Capacitor color code to value conversion
- Value to capacitor color code conversion
- SMD capacitor code to value conversion
- SMD value to EIA code calculation
- Supports standard and SMD capacitors

The Capacitor Converter is the perfect tool for anyone working with electronics – from hobbyists and students to professional technicians. Simply select the color bands and instantly see the corresponding capacitor value. Or enter a value and let the app calculate the correct color bands automatically. SMD capacitors are fully supported as well: enter the capacitor code → the value is calculated. Enter the value → the matching EIA code is generated. The app works completely offline, is fast, intuitive, and requires no registration. Perfect for workshops, labs, education, and DIY electronics projects. Key Features: Select color bands → instantly get the capacitor value Enter a value → automatically get the correct color bands Supports SMD capacitor codes: EIA‑3, EIA‑4, and EIA‑96 Fully offline, no registration required Ideal for electronics hobbyists, students, and professionals Clean interface and fast workflow The Capacitor Converter makes working with capacitor values easier, faster, and more reliable.

Verdict
The clearest difference is in-app purchases: Capacitor at none against AVR Tutorial's 10. Capacitor also leads on review sentiment (100% vs 75%) and ratings volume (10 vs 2). AVR Tutorial's advantage is update cadence (every 3 months vs every 40 months) and rating (5.0 vs 4.8). On price, ads and device support there is nothing between them.

Both are free to download. AVR Tutorial sells 10 one-off in-app purchases. Capacitor asks for nothing beyond the download.
AVR Tutorial holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Capacitor has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of AVR Tutorial's written reviews are positive against 100% of Capacitor's, so the app with the better star average is not the one people write more warmly about.
AVR Tutorial ships an update every 3 months, Capacitor every 40 months. The most recent releases landed on September 26, 2026 and September 9, 2026 respectively.
