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.

Description This is the BEST app to learn about Resistors and Circuit Resistance (Equivalent Resistance). This virtual lab provides an excellent environment for anyone who is interested in understanding series and parallel resistors, learning how to measure voltages across resistors, current through series and parallel circuits and solving simple circuits. Features - VERY SIMPLE and EASY TO USE, with up to eight component sections. - Component sections can easily be configured from five different types. - VIRTUAL "Hands On" experience using volt and amp meters. - Resistor values can easily be changed with a picker, keypad or using randomize button. - Circuit voltage can easily be changed from 1 to 1000 volts with a picker or a keypad. - The "Basics" screen make this app unique for the simplicity and speed of seeing the effects of "Opens" (resistor component with infinite resistance) and "Shorts" (resistor component with zero resistance). - FREE and NO ADVERTISEMENTS. - The circuit is always "LIVE" and immediately shows voltage, current and circuit resistance with any changes made to the circuit.

Verdict
The clearest difference is rating: AVR Tutorial at 5.0 against Simple Circuit Builder's 4.0. AVR Tutorial also leads on review sentiment (75% vs 53%) and iOS requirement (9.0 vs 14.0). Simple Circuit Builder's advantage is in-app purchases (none vs 10) and update cadence (every 3 weeks vs every 3 months). On price, ads and device support there is nothing between them.
